Easy to learn

I was pleasantly surprised at how easy it is to customize my Garmin Mk3i. The Dive Master (Dan) at First Coast Divers here in Jacksonville Fl, is very knowledgeable and provided perfect instructions on how to use.

great everyday watch that you can use for divin a

Got the Descent MK3i 51mm as a replacement for my FR945 as it was showing it's age. Note, I didn't get the transmitter, so can't comment about the integration. As an everyday watch, it's great. I really like the new features such as dive & training readiness from the glances. As a dive watch, I am still getting used to it, and I will be comparing it to the larger Shearwater models (Peregrin & Perdix). I also dive normally in cold water, with drygloves and lose a good amount of dexterity. Screen is great & bright. The large number model is a really nice feature. I really like the pool move feature as well. The customization of fields is nice. Battery life is great as well. With the drygloves, I do find the larger buttons on the perdix / peregrin easier to trigger, but I suspect it will take time to get used to. I do love how since it's paired with my phone, I don't need to manually sync my dives.

This watch is everything I need

I had an Epix for a few years and loved it. Also a diver so had a separate lower level dive computer to take on trips. Super excited to have a great dive computer in the same package of an otherwise amazing Garmin watch.

Worth The Upgrade

Upgraded from the Mk2i, which I felt was a solid performing dive/adventure watch. The Mk3i takes it to another level, most notably the AMOLED display. Several dives on this watch have proven it to be as solid, if not slightly more so, as the Mk2i.

love love love

I recently purchased the Garmin MK3i, primarily because I was looking for a device that could track my sleep and heart rate, and also serve as an upgrade for my dive computer. After using it for a while, I can confidently say that it has exceeded my expectations in many ways. First and foremost, I love how the Garmin MK3i looks on my wrist. The sleek and modern design not only makes it a functional piece of technology but also a stylish accessory. It feels sturdy and well-made, which is exactly what you want from a high-end smartwatch. The MK3i is packed with features. The sleep tracking is incredibly detailed, providing insights into the quality of my rest, including the different sleep stages. The heart rate monitor is accurate and helps me keep an eye on my cardiovascular health throughout the day. One of the standout features for me is the workout tracking. Whether I'm running, cycling, or doing a gym session, the MK3i tracks all my activities with impressive accuracy. The data it provides is comprehensive and helps me understand my performance and progress over time. As someone who enjoys diving, the upgrade on the dive computer is a significant benefit. The dive mode is intuitive and provides all the critical information needed underwater, making my dives safer and more enjoyable. Although I'm thrilled with my purchase, I must admit that there is still a lot to learn. The sheer number of features can be overwhelming at first, and it takes time to explore and understand everything the watch offers. However, the effort is well worth it, as each feature adds significant value to the overall experience. Overall, the Garmin MK3i is an excellent investment for anyone looking for a multifunctional smartwatch that excels in fitness tracking and diving capabilities. Its elegant design, robust build, and extensive feature set make it a standout device. While there is a learning curve, the rewards are worth it. I highly recommend the Garmin MK3i to anyone in the market for a high-quality smartwatch.

Best everyday dive computer and watch

I've had the Apple Watch, the Garmin Descent mk1 and other speciality watches. Got the mk3 prior to a cruise and dive trip and this by far the best everyday device and dive comp combination ever. I've also used it for golf and workouts and at work. Very flexible and customizable. The best thing is the battery life. It's been days since I charged it and still have days left. Took it to Bonaire and it had me ahead of everything on the dive. Best watch I've ever had. Ever going to the Apple Watch again.

Love diving and living with my Mk3i

I previously owned a 51mm Epix Pro Gen 2 sapphire and loved it. I do karate, swimming, walking, and other outdoor activities. I was a previous Apple Watch Ultra user but made the switch and never went back. I got my OW certification and found out the Epix is not dive-certified so I sold it, pretty much for what I paid for it, and got the Mk3i. It's amazing!!! I have the air integration which is nice, the dive maps show me where I enter and exit, and all the underwater stats have replaced a paper log. I am glad I made this purchase and my other watch pretty much paid for half of this one.

Lack of Firections

Upon receiving the watch and looking at the enclosed instruction books, I'm glad we had an electron microscope to read the fine print. I did find many videos of eventually that are YouTube videos that you have to go on the web to get in order to try to understand what the Watch can and can't do?..!!!! It's a great watch but again it's overwhelming to try to figure all of it out upon yourself. I would suggest that Garmin set up three levels of training for the watch with videos. One level is the beginning level. The second level is intermediate and getting around and moving and adding apps and other instructions, and the third level would be advance level, which could be used in depth directions, and analysis of the operates

An amazing dive computer and daily wearable

I had the original Apple Watch and quickly returned it as I felt it was very half-baked and unnecessary. Wow has a lot changed. I love the Descent Mk3i, I enjoy all the health metrics and usefulness out of the water, but it really shines when diving. I had a Shearwater Perdix around 8 years ago and the Garmin does everything I used the Perdix for and then some. I'm very pleased with the watch and highly recommend it.

Initial Thought, WOW

Bought the 3i as my primary computer and moved my 2i to second computer status. Screen, battery life and light in the 53 mm are fantastic. Won't be able to evaluate the dive computer function fully until June in the South Pacific. Golf and all my other activity functions are still great.

Great all around watch. Horrible sleep tracker

This thing is incredible with how much it can do. However, I don't think it really does any one thing all that great. The dive features are fantastic. I feel like it's a dive watch first and a smart watch second. But for the price, this thing should blow the Apple Watch away plus be a fantastic dive watch. My biggest complaint is the sleep tracking. It's useless which throws off your dive readiness and your training readiness. Having come from the Apple Watch Ultra. I will certainly miss the accuracy of the sleep tracking.

I bought my first mk3i and it stopped working. They were very good in replacing it quickly. It often will not read my tank pressure then it will. I give it a solid good but not great

Could be better.

I bought this watch for the dive computer and functions. It is also a smart watch. GPS could be better and have a stronger signal. Maps take a while to update to current location. Watch is loaded with sports features, but they all have the same data. All these sports and the only features they have are timers, heart rate, it's all the same, over and over. Watch needs more layout, more clock appearances, more color choices. Flashlight is bright and gets the job done. Tac light was a very good choice. Only complaints are the GPS positioning takes too long to update and all the different sports have the same features and data.

Great, needs software updates to be perfect.

???? The Garmin Mk3i watch is almost perfect for my active lifestyle. Whether I'm pounding the pavement on a run, gliding through the water in my kayak, or exploring the depths while scuba diving, this watch has me covered. One of the standout benefits of Garmin ecosystem for me is how seamlessly the Garmin Connect software integrates all my activities, making it easy to track and analyze my performance. The training programs available are a bonus, helping me stay on top of my fitness goals. The built-in flashlight was a nice surprise. It was an unexpected addition that's proven to be useful on many occasions. When I'm diving in the ocean, the in-reach communication feature provides invaluable peace of mind. However, it's important to note that in-reach communication requires a separate device and subscription. The GPS, compass, and maps functionalities are spot-on, enhancing my outdoor adventures. And I must mention, the new bright screen is a great improvement, ensuring visibility even in bright sunlight. However, the data screens for diving have limited customization. If you want to see your gas pressure, there is basically one data field that can be changed on that screen. Hopefully, this will be fixed through software updates in the future. Despite this minor hiccup, the watch excels in all other areas. Overall, the Garmin Mk3i is a great companion for any activity, with just a few tweaks to Scuba Diving screens needed to reach perfection.

Keeps Getting Better!

I started out years ago to buy a smart waterproof smartwatch. No one had a watch that had sustained battery power or reserves. Settled on the fenix series. It was great, but lacking in a few features I would like to have. Then the MK series came out - wow, excellent replacement for my fenix. The MK 2i was my travel/outdoors and health buddy. Always wished for an amoled display that the iWatches had but I was not a 1 day battery life. Then the MK 3i was unveiled - with all my hopes and dreams in a computer dive/smartwatch. I am in heaven. Garmin is always on the cutting edge of delivering what we are looking for. An excellent addition to the MK series. Way to go!!!!

Looks Great - Battery Life is Amazing

I give it a 3 not because of the watch itself but because there is no way to transfer my dive logs to the Garmin Dive app from the Current Dive app I use and my Current Dive app will not connect with the watch. to have to enter every one of my dives manually into the Garmin Dive app is EXTREMELY INCONVENIENT, BUT the watch is Gorgeous and I Love it.

Amazing Watch

I LOVE this watch. Have had a Fenix 5 for many years, but as I do like to dive, have been waiting for the new version of the dive watch to upgrade. This thing is a beast! All the amazing features of the Fenix/Epix series I've been wanting in an upgrade, but add on completely insane diving capability as well. Only 7 dives so far with the new watch and T2 transmitter, but works flawless! So glad I waited for this one!

MK3i Superstar

I upgraded from the Garmin Epix 2 in order to add the dive features. I've done a couple of dives and have the T1 transmitter as well and LOVE the set up! It gives me all the vital info I need and works perfectly. I love having all the same features for my daily work outs and activities plus having the ability to dive with this computer! Super happy!

Great features! However still having some issues

I bought this watch because I am an active scuba diver and active sailor. There are many things I like about the Mk 3i (43mm) and many things I do not like. I wish the watch would automatically going into sleep mode, the battery life is not as good as advertised. Watch seems glitchy at times and when on do not disturb mode at night it will still buzz with notifications. I am not sure if I have a defective unit or not.
