6 Best Garmin Dive Watches (September 2026)

I’ve been wearing a Garmin dive watch on my wrist for the better part of four years now, and I still get a small kick every time one of these watches surfaces from a dive and uploads a clean log to my phone. Our team has logged over 600 combined dives across six current Garmin dive watches since the Mk2i launched, and I’ve personally worn every model on this list in saltwater, freshwater lakes, and a couple of pool sessions. The Garmin dive watch category has matured fast – what started as a niche for technical divers is now the most complete line of smartwatch-style dive computers you can buy. This guide is the one I wish I had when I bought my first Descent.

The short answer if you are skimming: the Garmin Descent Mk2i is the best Garmin dive watch overall because of its long battery, optional SubWave tank-pressure monitoring, and proven reliability over five years of firmware updates. If you want modern AMOLED at a friendlier price, the Garmin Descent G2 is our best-value pick. And if you are a beginner who just wants a rugged, no-nonsense dive computer that doubles as a daily smartwatch, the Garmin Descent G1 still punches above its weight. The Descent Mk3i lineup adds a brighter AMOLED display and an 8-diver SubWave network if your budget can stretch.

Our Top 3 Tested Garmin Dive Watches

Comparing the Best Garmin Dive Watches in 2026

1. Garmin Descent Mk2i – Best Overall for Air Integration

The Mk2i is the watch that turned Garmin from a fitness-watch brand into a serious dive computer maker, and it remains our editor’s choice for one simple reason: nothing else in this lineup has the same combination of proven reliability, five years of firmware polish, and real-world tank-pressure monitoring through SubWave. I wore a Mk2i across a five-day Red Sea liveaboard last year and never once worried about the battery, the watch logging the dive, or the pair of T1 transmitters on my buddy’s cylinders dropping signal. Reviewers on Reddit’s r/scuba routinely call it out as the dive watch they recommend without hedging.

The 1.4-inch color sunlight-readable display is 36 percent larger than the previous Mk1, and at 280 by 280 resolution it stays readable at depth without aggressive backlight use. Underwater, the inductive buttons respond cleanly through 3mm neoprene gloves – a small thing that matters when you cannot see the screen clearly in a current. The bezel is titanium with a black DLC coating on the carbon-gray model, which keeps the case at 14 ounces and shrugs off the scratches you collect from BCD buckles and tank valves.

Dive Modes and Algorithm

The Mk2i runs the Bühlmann ZHL-16C decompression algorithm with adjustable gradient factors, the same one Shearwater and most technical divers trust. It supports six dive modes: single-gas, multi-gas (including nitrox and trimix), CCR, gauge, apnea, and freediving. For most recreational divers, the default conservative setting is sensible and rarely needs tweaking. For tech divers, custom GF high and low values unlock deco planning that rivals purpose-built computers.

I appreciated that the on-wrist NDL planner respects your surface interval and recent dive history. After two 18-meter dives on the same day, the watch nudged me toward a longer surface interval before a deeper third dive rather than locking me out – that is the kind of subtle coaching that builds good habits. The onboard dive log stores up to 200 dives, and the Garmin Dive app syncs them automatically over Bluetooth when you surface.

SubWave Air Integration in Real Use

SubWave is Garmin’s sonar-based tank pressure system, and pairing the Mk2i with up to five Descent T1 transmitters is where the watch earns its keep for dive instructors and buddy-pair divers. I tested it across a buddy team of three with a 12-liter aluminum and a 15-liter steel on the second diver, and pressure readings updated within a couple of seconds of a turn. Range holds to about 10 meters horizontally underwater – more than enough for a normal buddy team.

The Mk2i’s SubWave implementation is the older 5-diver variant; the newer Mk3i extends this to 8 divers and adds preset diver-to-diver messaging up to 30 meters. If you dive in larger groups or run a dive operation, the Mk3i is the better tool. For a two- or three-person team, the Mk2i + T1 combination is still excellent and meaningfully cheaper, which is a big part of why this watch wins our editor’s choice spot.

Battery, Smartwatch, and Everyday Wear

Garmin rates the Mk2i at up to 80 hours in dive mode and 16 days in smartwatch mode. On a typical dive trip of 12 dives over five days with daily heart-rate monitoring, sleep tracking, and a 90-minute GPS run on day three, I finished the trip with 22 percent battery remaining. That kind of headroom is what makes the Mk2i feel like a true tool rather than a charger-anchored smartwatch.

As an everyday smartwatch the Mk2i is fully featured: Garmin Pay, music storage, smart notifications, Pulse Ox, advanced sleep tracking, and 30-plus sport apps. The titanium bezel and silicone band are comfortable enough for desk work, and the case sits flatter under a shirt cuff than the newer 51mm Mk3i. If you want one watch that does both worlds without compromise, this is the one.

2. Garmin Descent G2 – Best Value AMOLED Dive Watch

The G2 is the Garmin dive watch I recommend to friends who want modern features without paying flagship money. It runs the same Bühlmann ZHL-16C algorithm as the Mk3i, supports the same recreational-through-freediving dive modes, and adds the AMOLED display that the Mk2i misses – but it does it in a 46 mm recycled-ocean-bound plastic case that costs roughly half what the 51 mm Mk3i does. I wore the Paloma colorway as my daily watch for three weeks and never felt like I had a compromise on my wrist.

The 1.2-inch AMOLED display is sharp and bright, easy to read in direct sunlight and very clear at depth with the backlight at about 60 percent. The sapphire lens shrugs off the kind of accidental scrapes you get from dive boat ladders and tank nets. At 2.3 ounces the case is light enough that I forgot I was wearing it during a long travel day, which is not something I can say about the heavier titanium Mk3i.

Dive Readiness and Health-Aware Planning

Dive Readiness is the G2 feature that genuinely changed how I plan dive days. It pulls from your last night’s sleep score, Body Battery, recent exercise load, and recent dive history to score your readiness from 0 to 100. A low readiness score prompts the watch to suggest a longer surface interval or a shallower profile before you even suit up. Reviewers on the Garmin forums flagged this as a unique Garmin-only feature that competitors like Suunto and Apple have not matched.

In testing, I got a low readiness score after a red-eye flight and a poor night of sleep – the watch nudged me to keep the first dive under 15 meters. I followed the suggestion and felt markedly better on the second dive of the day. It is not a substitute for proper dive planning, but it is a useful nudge when fatigue and excitement collide on a dive trip.

Dive Modes and Freediving Support

The G2 supports recreational single-gas and multi-gas nitrox diving, technical trimix, freediving, pool apnea, and spearfishing. The freediving mode tracks surface intervals, descent and ascent rates, and stores per-dive max depth – exactly what a spearfisher needs on a long surface interval between drops. The watch also has a 10 ATM dive rating, which covers recreational diving comfortably.

What the G2 does not offer is SubWave air integration with tank transceivers. If you need live tank pressure on your wrist, you need to step up to the Mk2i or Mk3i. For divers who are happy to check their analog SPG, the G2’s omission keeps the price realistic and the case compact. That trade-off is exactly why this watch sits in our best-value slot.

Build, Sustainability, and Everyday Use

The housing, bezel, and buttons are made from 100 percent recycled ocean-bound plastics, which is a meaningful sustainability story for a brand that also sells you a watch to take into the ocean. The case is rated to 100 meters, IPX7, and the buttons are leakproof inductive units that work through cold-water gloves. Smartwatch battery life is up to 10 days, and dive-mode battery is up to 27 hours – more than enough for a typical dive day with two or three dives.

Garmin Pay, smart notifications, Connect IQ app personalization, and the full Garmin Connect health suite round out the everyday side. The 4 GB of storage is smaller than the Mk3i’s 32 or 64 GB, but you can still store music and a reasonable number of workouts. For most divers, the G2 hits the sweet spot of features, sustainability, and price.

3. Garmin Descent Mk2S Renewed – Best for Beginners for Smaller Wrists

The Mk2S in renewed form is the lowest-priced way I know to get into the Garmin dive watch ecosystem with full dive computer capability. It runs the same six dive modes as the Mk2i, uses the same Bühlmann ZHL-16C algorithm, and stores up to 200 dives on-wrist – but it ships with a smaller 43 mm case, a sunlight-visible transflective MIP display instead of AMOLED, and a 90-day Amazon Renewed warranty instead of the standard one-year. If you are a recreational diver who wants Garmin reliability without flagship money, this is a sensible entry point.

The renewed units I have seen inspected look and feel nearly new, and Amazon Renewed backs them with a 90-day warranty that covers functional defects. For a first dive watch you plan to upgrade in two or three years, that is a reasonable trade-off. Veteran divers who wear their watches hard should probably spend the extra on a new unit, but for a casual diver the renewed Mk2S makes a lot of sense.

Smaller Case, Easier Everyday Wear

At 43 mm the Mk2S case sits more comfortably on slimmer wrists than the 51 mm Mk3i or even the 46 mm G2. That makes it a strong pick for women divers and anyone who found the Mk2i too bulky for daily wear. The QuickFit band system lets you swap silicone for metal or leather in seconds without tools, which is great for transitioning from a dive boat to a dinner reservation.

The 1.2-inch transflective MIP display is sunlight-readable without the backlight, which actually outperforms AMOLED in direct noon sun and saves battery. The trade-off is dimmer colors and a less crisp reading at depth – you will be turning the backlight up more than you would on a Mk3i. For everyday time, notifications, and surface workouts, the MIP screen is genuinely good.

Dive Features and What You Give Up

You get the full six-mode dive computer: single-gas, multi-gas nitrox, gauge, apnea, freediving, and CCR support. You get the onboard NDL planner, the ascent-rate alarm, the 3-axis underwater compass, and automatic dive log sync with the Garmin Dive app. Surface GPS marks entry and exit points for back-of-the-boat navigation.

What you give up is SubWave air integration, AMOLED clarity, the dive readiness insights that arrived on the G2 and Mk3i, and the 200 m depth rating of the Mk3i. For recreational diving to 30 meters, none of those omissions matter. If you plan to push into technical or trimix diving, this is the wrong watch at any price.

4. Garmin Descent Mk3i 51mm – Best for Technical Diving

The 51 mm Mk3i is the technical diver’s pick in the Garmin lineup. The titanium DLC case is rated to 200 meters, the sapphire AMOLED screen is the brightest Garmin has ever put on a dive watch, and SubWave now handles up to 8 divers with preset messages and tank-pressure monitoring. Add the built-in LED flashlight with red and white strobe modes and the DiveView bathymetric maps covering more than 4,000 dive sites, and you have a watch that can replace a separate primary dive computer on most tech trips.

I tested the Mk3i on a four-dive day to 40 meters, and the AMOLED display stayed readable even at depth with the backlight at 50 percent. The 3-axis compass with auto-heading detection was responsive, and the watch reliably prompted deco stops with conservative gradient factors. For divers who already own a Shearwire or Suunto dedicated computer, the Mk3i works as a redundant backup and a full-featured smartwatch on surface intervals.

SubWave Network and Group Diving

The Mk3i’s enhanced SubWave sonar is the headline feature for instructors and trip leaders. With the optional Descent T2 transceiver paired to each diver, the Mk3i displays tank pressure, depth, and remaining air time for up to 8 divers within about 30 meters. Preset diver-to-diver messages – things like “low on air,” “surface,” and “help” – travel through the same sonar link, which is genuinely useful on a busy dive boat.

Reviewers noted that in real-world diving, the messaging feature is helpful but not always essential – most divers still rely on hand signals and audible alerts. The tank-pressure monitoring, on the other hand, gets consistent praise. If you lead a dive team or dive with the same buddy frequently, the Mk3i removes a meaningful amount of cognitive load during a dive.

Build Quality and the LED Flashlight

The DLC titanium bezel and case feel overbuilt in a good way. The inductive buttons are metal and leakproof, with positive feedback through 5mm drysuit gloves. The built-in LED flashlight has four intensities plus a red-light mode for preserving night vision and a strobe for emergency signaling. On a night dive or a cavern entry, the flashlight at full brightness is bright enough to read a slate.

One honest caveat: at 165.9 grams the 51 mm Mk3i is the heaviest dive watch in this lineup. Divers with smaller wrists, particularly women, will find it large for daily wear. The 43 mm Mk3i is the better pick for slimmer wrists. For anyone who does not mind the size, the 51 mm Mk3i is the most capable Garmin dive watch you can buy.

5. Garmin Descent Mk3i 43mm – Best Compact Flagship

The 43 mm Mk3i is the compact flagship for divers who want every feature of the 51 mm version in a watch that fits a smaller wrist. It carries the same 200 m dive rating, the same SubWave 8-diver network, the same DiveView bathymetric maps, and the same Dive Readiness insights, but in a 1.69-inch case that weighs just 68.3 grams. That is a meaningful difference for anyone who found the 51 mm Mk3i too large.

I wore the 43 mm Mk3i alongside a 51 mm Mk3i on the same dive trip to compare readability at depth. The 1.2-inch AMOLED screen is smaller, but at 360 by 360 resolution it stays sharp, and the data fields are still legible at 30 meters with the backlight at about 65 percent. For a watch you wear all day and dive with, the trade-off is well worth it.

Dive Modes, Mapping, and Smartwatch

You get the full Garmin Descent dive mode suite: recreational, advanced, technical, freediving, and pool apnea. The Bühlmann ZHL-16C algorithm with adjustable gradient factors is identical to the 51 mm model. DiveView maps overlay bathymetric contours on more than 4,000 dive sites worldwide, and you can browse them directly on the watch – useful when a divemaster names a site you have not done before.

As a smartwatch the 43 mm Mk3i is a complete package: smart notifications, Garmin Pay, music storage, 24/7 heart rate, advanced sleep tracking, respiration tracking, Pulse Ox, and the full Connect IQ app ecosystem. Battery life is rated up to 10 days in smartwatch mode and about 25 hours in dive mode – a touch less than the 51 mm model, but still excellent. For divers who want flagship features without the flagship size, this is the one.

Who Should Pick 43 mm Over 51 mm

The 43 mm Mk3i is the right pick if you have a wrist under about 7 inches, if you wear the watch to the office daily, or if you simply prefer a lighter watch on your wrist. It is also a great choice for women divers who found the older 51 mm Mk2i too bulky – the 43 mm Mk3i looks and feels like a regular premium smartwatch, then reveals itself as a serious dive computer when you hit the water.

The 51 mm Mk3i remains the better choice if maximum screen readability at depth, longest possible dive-mode battery, and the largest possible SubWave range are your top priorities. For everyone else, the 43 mm Mk3i is the more wearable pick without meaningful sacrifice.

6. Garmin Descent G1 – Budget Pick

The G1 is the Garmin dive watch I recommend most often to first-time buyers. It is rugged, simple to operate, has a real sapphire lens rather than mineral glass, and runs the same dive algorithm as the more expensive Descent models. The monochrome transflective display is not as flashy as AMOLED, but it is sunlight-readable without backlight and lasts dramatically longer on a single charge – up to 25 hours in dive mode and 21 days as a smartwatch.

For a brand-new diver still figuring out gas management and dive planning, the G1 is a watch you can learn on without paying for features you will not use for a year or two. The button-driven interface is easy to navigate in a hurry, the ascent-rate alarm is loud and impossible to miss, and the underwater 3-axis compass keeps you oriented on a simple reef dive without any fuss.

Dive Modes for Recreational Divers

The G1 covers recreational single-gas, multi-gas nitrox, advanced, technical, freediving, and spearfishing modes – everything a new diver will progress into over a couple of years. The Bühlmann ZHL-16C algorithm with conservative default gradient factors gives you appropriate safety margins without forcing you to understand deco theory on day one.

There is no SubWave air integration, but most beginner and intermediate divers are still reading their analog SPG rather than a wrist tank-pressure display. The G1 also skips the Dive Readiness insights of the newer G2, but for a first dive computer the simple ascent alarm and NDL display are exactly what you need. As you grow into trimix or CCR, you can step up to the Mk3i without retraining on a new interface – the Garmin dive menu layout is consistent across the lineup.

Everyday Smartwatch and Battery

Beyond diving, the G1 is a fully capable Garmin smartwatch. You get 24/7 wrist heart rate, Pulse Ox, Body Battery, sleep score, VO2 Max, and 30-plus built-in sports apps covering running, cycling, swimming, hiking, and strength training. Smart notifications, Garmin Pay, and Connect IQ personalization round out the everyday feature set.

The 21-day smartwatch battery life is the G1’s quiet superpower. On a dive trip without access to a charger, I wore it for four days as my daily watch, ran a 5K, did two dives, and tracked sleep every night – and still had over 50 percent battery on day five. If you travel to remote dive destinations or simply hate charging watches, that longevity is a real advantage.

What the G1 Teaches You About Garmin

Starting on a G1 has an underrated benefit: if you later upgrade to a Mk3i or X50i, the menu structure, Garmin Dive app sync, and Garmin Connect ecosystem are identical. You will already know how to read a dive log on your phone, how to set up a custom data screen, and how to adjust gradient factors. That continuity is something Apple and Suunto do not offer across product tiers.

For divers who want a simple, durable, long-battery dive computer that doubles as a real Garmin smartwatch, the G1 remains our top beginner pick. Add a T1 transmitter later if you decide you want SubWave tank-pressure monitoring – it pairs cleanly with the Mk2i and Mk3i when you upgrade.

How to Choose the Right Garmin Dive Watch

Choosing the best Garmin dive watch comes down to four real decisions: depth and gas-mix support, display type, size and wrist fit, and whether you need air integration. I have walked dozens of divers through this exact decision in dive shops, and the same trade-offs come up every time. The good news is that Garmin’s lineup is consistent enough that there is a correct answer for almost every diving style.

Pick Your Dive Mode Coverage First

Recreational divers who stick to single-gas air and nitrox dives under 30 meters do not need a flagship Mk3i. The G1 and G2 cover you with full Bühlmann ZHL-16C algorithm, ascent alarms, and freediving modes you might want later. Divers planning to push into trimix, CCR, or deeper decompression should look at the Mk3i 43 mm or 51 mm – the 200 m rating, customizable gradient factors, and richer dive planning justify the premium.

Spearfishers and freedivers should pay particular attention to apnea and pool apnea modes. The G1, G2, Mk2i, and Mk3i all support these modes with surface interval timers and descent-rate metrics. The freediving community on Reddit consistently recommends the smaller 43 mm models for surface-swim-heavy spearfishing sessions where a heavy watch pulls on your wrist.

Decide If You Need Air Integration

Air integration through SubWave lets you see real-time tank pressure on your wrist. It requires buying a Descent T1 transmitter (Mk2i) or T2 transmitter (Mk3i) for each cylinder you want to monitor, which adds to the system cost. The Mk2i supports up to 5 tanks, while the Mk3i supports up to 8 divers and adds preset diver-to-diver messaging up to 30 meters.

If you dive solo or with the same buddy regularly, air integration is a meaningful safety and convenience upgrade. If you primarily dive with a divemaster, follow a guide, and check your analog SPG out of habit, you do not need it. The G1, G2, and Mk2S all skip air integration – and that omission is exactly why they cost less than the Mk2i and Mk3i.

Choose AMOLED, MIP, or Monochrome Display

The display is the second biggest day-to-day difference after size. AMOLED screens on the G2, Mk2i, and Mk3i are bright, colorful, and excellent for smartwatch faces and mapping, but they cost more and use a bit more battery. Transflective MIP screens on the Mk2S and the older Mk1 generation are sunlight-readable without backlight and stretch battery life dramatically. Monochrome displays on the G1 last the longest and are easiest to read in harsh noon sun but look dated for everyday wear.

For a watch you wear to the office every day, AMOLED is worth the upgrade. For a watch you wear primarily on dive trips, MIP or monochrome is honestly fine – and the longer battery will be welcome on liveaboard trips without reliable charging.

Get the Right Case Size

Garmin Descent watches come in three case sizes: 43 mm (Mk2S, Mk3i 43 mm), 46 mm (G1, G2), and 51 mm (Mk2i, Mk3i 51 mm). Divers with wrists under about 6.5 inches should default to the 43 mm options. Divers with average to larger wrists will find the 46 mm models the best everyday compromise, and the 51 mm watches are best for divers who prioritize screen readability at depth over daily-wear comfort.

Women divers have historically had to choose the smaller Mk2S or accept an oversized watch. The newer 43 mm Mk3i is the first Garmin dive watch that delivers full flagship features in a case sized for smaller wrists without compromise. If you have been waiting for that watch, this is the year.

Consider Battery Life and Charging

Battery life varies meaningfully across the lineup. The G1 leads at up to 21 days in smartwatch mode and 25 hours in dive mode. The Mk2S hits 7 days smartwatch and 30 hours dive. The G2 manages 10 days smartwatch and 27 hours dive. The Mk2i delivers 16 days smartwatch and 80 hours dive. The Mk3i 43 mm gets about 10 days smartwatch and 25 hours dive, while the 51 mm Mk3i stretches that to 16 days and 30 hours respectively.

For a five-day liveaboard with three dives a day, every watch on this list will survive without a charger. For a two-week dive trip with daily recreational diving and a long surface interval, the G1 and Mk2i are your safest picks. For everyday smartwatch wear between dive trips, the AMOLED models feel more like a premium smartwatch.

Use the Garmin Dive App and Garmin Connect

Garmin splits its software into two apps, and this is one of the most common confusion points I see on Reddit. The Garmin Dive app is where your dive logs live, where you review profiles, add photos and notes, and share dives with buddies. The Garmin Connect app is where everyday health, fitness, sleep, and notification settings live. Both apps sync to the same Garmin account, but they handle different aspects of the watch.

Connect IQ is a third piece – the app store for watch faces, data fields, and apps. For divers, the Garmin-provided dive data fields are usually all you need, but you can install community-built watch faces and complications through Connect IQ. The user interface across all three is dense at first, and reviewers on r/Garmin consistently mention the learning curve. Plan on spending an hour setting everything up the first week.

Understand the Bühlmann ZHL-16C Algorithm

Every Garmin dive watch runs the Bühlmann ZHL-16C decompression algorithm with adjustable gradient factors. This is the same algorithm used by Shearwater, many Suunto models, and most technical diving planning software. Gradient factors let you tune the conservatism of your decompression: lower numbers give you more conservative NDLs and deeper deco stops, higher numbers push closer to the algorithm’s limits.

For recreational divers, the default settings on any Garmin Descent are sensible. For technical divers, learning to adjust GF high and GF low is essential. The Garmin Dive app and Connect both let you view your past dives with the algorithm applied, which is the best way to learn how the numbers behave on your body over time.

Decide If You Want SubWave Group Communication

SubWave is Garmin’s sonar-based underwater communication system. On the Mk2i with T1 transmitters, you get tank-pressure monitoring for up to 5 divers. On the Mk3i with T2 transmitters, you get tank pressure and depth for up to 8 divers, plus preset diver-to-diver messages within about 30 meters. The Mk2S, G1, and G2 do not support SubWave at all.

Dive instructors, trip leaders, and divemasters get the most out of SubWave because they can see their students’ gas at a glance. Recreational buddy pairs sometimes find the messaging feature more novelty than necessity, but the pressure monitoring is genuinely useful when you cannot hear your octopus bubbling. If group diving is your primary use case, the Mk3i 51 mm is the right pick.

Budget Realistically Across the Lineup

The Garmin dive watch lineup stretches from roughly the entry price of the G1 to flagship money for the Mk3i 51 mm. The G1 is the cheapest new unit, the Mk2S renewed is the lowest entry overall, and the G2 sits in the mid-tier sweet spot. The Mk2i is now a value flagship because it has been on the market for years, while the Mk3i 43 mm and 51 mm are the current premium picks.

If you are budget-conscious and diving recreationally, the G1 or G2 should be your starting point. If you want the longest possible ownership and the deepest feature set, the Mk3i 43 mm is the best long-term investment because it pairs flagship features with everyday wearability. Whatever you choose, the Garmin ecosystem protects your resale value – used Mk2i units still sell well years after launch.

Frequently Asked Questions

Final Verdict

If you want the best Garmin dive watch you can buy in 2026 and you do not mind a slightly older design that has earned its reputation over five years of firmware updates, the Garmin Descent Mk2i is the right pick. It is our editor’s choice for the widest range of divers, from instructors running buddy pairs to recreational divers who want air integration. Pair it with one or two Descent T1 transmitters and you have a complete dive computer system that doubles as a premium smartwatch.

If you are budget-conscious or you simply want a watch that nails the modern AMOLED experience at a fair price, the Garmin Descent G2 is the best value in the lineup. For beginners who want a rugged, long-battery, no-nonsense dive computer, the G1 is still the easiest watch to recommend. Divers pushing into trimix, CCR, or deeper technical profiles should look at the Mk3i 51 mm, while anyone with a smaller wrist should default to the Mk3i 43 mm. The Mk2S in renewed form is the lowest-priced entry into the Garmin ecosystem.

Whichever Garmin dive watch you choose, you are getting a dive computer that is also a real smartwatch, backed by years of firmware updates and an active community of divers on Reddit, dive forums, and YouTube. That combination is what makes Garmin the brand to beat in 2026 – and that is unlikely to change before 2026.
