As an owner of the original D2 Delta PX aviator watch, I was skeptical whether there would be any significant improvement to this version. I am here to tell you the answer is a BIG YES! It is better in every way other than battery life (which was already excellent). Large display, bright, touch controls, METAR at a glance, runway crosswinds, one press switch to TAF, quick airfield lookups, plus all the other Garmin Fitness, Running, & Golf apps! What is the most surprising feature? The built-in flashlight. Yep, it's actually very usable! Leaving your watch on at night to track sleep & heart behaviors? Great metrics!! If you are an active aviator looking for some useful tech on your wrist, this watch is well worth the price! If you are not an aviator, I would look to other Garmin devices and save a few bucks and still have many of the health & activity features. Read more

The Garmin D2 Mach1 Pro is exceeding my expectations. It performs all the functions I was interested in and more. I found most of the functions very intuitive. If I have any trouble finding what I'm looking for, I just google The Garmin D2 Mach1 pro With my question and Google will walk me through the steps required to get what I'm looking for. Yes it is pricey but it's the best out there. I really like the automatic airplane flight logging feature. Read more

My husband is a pilot, he’s loving his new watch! He hasn’t even had to charge it yet! The features are insane and it truly gives me peace of mind to know he has all he needs on his wrist to be safe in the air and on the ground. Worth every penny and it was shipped overnight and arrived on time for Father’s Day! Very pleased and wouldn’t hesitate to buy another one! Read more

I am not a pilot, I just like aviation. I had a Fenix 7X Pro solar and got this for the screen. Its brighter, the battery life is roughly 2 weeks. On a commercial airplane its kinda hard to get a signal though. I thought I would be tracking my flights but unless you wanna hold to the glass the entire flight it wont do it. Overall though great watch! Heart rate and ECG are spot on in my opinion. Read more

I was super excited to get this watch and for $1400. It wasn’t cheap. But it has a ton of functionality and a lot of very pilot friendly capabilities. I was pumped that the battery life is up to 25 days when fully charged after having a Samsung sport watch that I would have to charge every night. Unfortunately, this watch seems to have a glitch and after I did some research on some forms, it seems to be kind of common that when it gets to around 40% the battery dies completely. So the 25 day battery life is not accurate. There are comments on the forms that if you do a software update, it will resolve it, but a lot of people still complain that they have the same problem even after software Updates. I updated everything when I took it out of the box and I had it happen to me as well, so there seems to be some glitch with Garmin. I’m considering returning it, it does last several days without a charge so it is still better than what I had before but don’t trust it when it says it’s at 40%. You might wake up the next morning to a completely black watch. And then when you plug it back in, it’ll tell you it has 40% and come back online but unless you plug it to charge, you can’t get it to work. Buyer beware, Garmin you screwed this one up. Or let’s just call it false advertising. Read more
