Better than Enduro 1 and a lot more expensive
The Garmin Enduro 2 is a multisport GPS watch designed for outdoor athletes and adventurers. It features a battery life of up to 150 hours in GPS mode with solar charging and up to 550 days in battery saver mode with solar charging. When not on the trail there's smartwatch mode, which can last up to 46 days with solar charging.
It also has SatIQ technology to maximize battery life without compromising positional accuracy. Overall, the Enduro 2 has about 40% more battery life than the Enduro 1. With multi-band GNSS that allows the Enduro 2 to utilize multiple satellite systems at the same time, it also has a better positional accuracy.
Another thing that's more accurate on the Enduro 2 compared to the 1 is the heart rate sensor due to better design and hardware.
The Enduro 2 uses traditional button controls in addition to the responsive new touchscreen interface to make sure you can access critical functions in any weather condition. There is no touchscreen feature on the Enduro 1.
An important feature of the Enduro 2 absent in the Enduro 1 is internal storage, which can be used for downloading maps for offline mapping and navigation and for storing media.
The newer generation Enduro is better in almost every way than the old one. But it's also a lot more expensive. The Enduro 2 retails for $1,099.99 while the Enduro 1 can be had for as low as $419.99.
