Depends on the context of essential. Essential for survival, no. Essential to have a good time, probably not.
I have the Garmin 6S Fenix ProSolar, I wear it everyday. I love it. I take it everywhere. Can I go without it, yes. Do I want to leave it at home, heck no. But I use it to track way points, keep me on track for the day depending on how much I have to hike, I’m also a female and it tracks all those pesky female things. It is a great fitness monitor, it has all sorts of fun gadgets to use, and it’s water proof.
one or more gifts or other benefits from the co-op.
