I will be in Colorado in October, and I am looking for a GPS unit. I already have an 5700 elite, I need something with top graphical maps. I want to be in the 300-500 very max range.
Garmin GPSMAP® 66i is a handheld GPS satellite communicator with features that include TOPO mapping, two-way messaging, direct to device BirdsEye Satellite Imagery & more.
If you do the garmin do the inreach. It is awesome. I carry one all hunting season.
That being said, I now use my phone with OnX MAPS and carry a standalone Inreach that pairs with my phone to text. I highly recommend, unless you are hunting in my zone...
I've ran the montana with onX for years but lately I have been just using onX on my phone (Samsung) . Using the phone is a lot smoother, better battery life, better visibility and is less bulky. The montana is rugged but I feel it's quite outdated. Whatever you choose onX is an absolute must.
