Garmin D2 Mach 2 Review - BIG Upgrade?

Detailed review of all the new features of the D2 Mach 2 Aviator Smartwatch from Garmin. What's different to the Mach 1, what does the watch do, and who is this watch for? If you're interested in a more budget-friendly option, check out the video I made about the Garmin D2 Air X15 here: This watch was sent to me to review by Garmin but I was not paid for this review, nor do they get to see what I say about this watch before this video goes live. But thank you to Garmin for letting me review this and share the features of this new watch with you here.
