Nice update, improvements over Mach 1

My perspective is based on I sold my Mach 1 and bought the Mach 2 as I am a nerd that way.
Unless you buy the pro with the LTE and satellite communications, this is a point upgrade not a dramatic change over the Mach 1. I did not buy the Pro because my iPhone has the same satellite emergency message send, and my wife has an Apple watch with LTE and has never used it for a call or a message...plus why only a gross leather band Garmin? The premium watch doesn't get the premium band?
I do love how multi functional this is from flying to golfing to running, fishing, and on and on. I use so many of the tools and functions on this watch it is worth every penny as I don't need a separate golf GPS, I don't need a separate running tracker, I love the consolidated aviation weather and the amazing screen and colors, and the best part is the crazy 25+ days without needing to recharge. Garmin addresses the biggest pain point all other watch manufacturers on the planet can't solve for which is battery life.
Another solid device I recommend to anyone.

Flight upgrade

It’s been almost three months since I bought this amazing watch, and I have no regrets. It’s the perfect supplement for pre-flight, flight, and post-flight activities. The synchronization with the G1000 is amazing.
