Garmin GPSMAP
Another plug for Garmin. Disclaimer, I’ve never used any but Garmin for trail riding.
I trail ride a lot where there isn’t any cell coverage and I don’t have a smart phone yet anyway. Not sure an app would work well in deep cover. The Garmin can lock onto up to 24 satellites. According to the boss, it hasn’t failed him yet.
My boss began letting me use his older Garmin GPSMAP 60 a few years ago. It’s one tough GPS. My boss said he has ran it over with his 4-wheeler, dropped it in water puddles a few times, it’s been rained on, he’s spilled gas on it and hasn’t been able to kill it yet.
I recently bought the newest version, Garmin GSPMAP 64st. Has lots of the features you are looking for. It is kind of old school, with buttons instead of a touch screen but it’s also very easy to read the screen in bright sunlight. From what I have read, the touch screen GPS’s can be hard to read outside and hard to use while wearing gloves on those cold days.
My only regret is I do wish I would have waited a bit to purchase it as the old version, GPSMAP 62, is now on clearance! I’ve seen some really great prices out there.
If you haven’t already purchased something, check these out.
