Summary: I'm sure this is a really nice unit, but it was too cumbersome for me to use it (I'm pretty technical savy, but not an electronics geek). I wanted a unit that was intuitive to use, and could basically route my hiking tracks to tell me how far I hiked and where the car is at.
Summary: I wanted this unit to perform but was let down. For it's stated features and capabilities it didn't appear accurate for a dedicated GPS. My iPhone feels like it has better accuracy (no back up data for this statement, just my opinion.). Maps slow to refresh and the unit eats batteries.
Summary: I bought this to replace a Garmin Montana that I have several issues with, but I was not able to see the screen in most outdoor light. I use it mostly for geocaching and I have to be able to see the screen in most light and that was not possible with this unit.
Summary: It has not that precision that it is advertised for. It gives coordinates the same way that a cheap GPS does. It uses a lot of battery (batteries gone in one hour use). It is not worth for the price.
Summary: Edit Feb 6, 2013 : I've used this now for a few days outside on my RZR riding the dirt roads around Sedona Arizona and find it very difficult and use especially in the sun or even shade for that matter. My Garmin 76 was not a problem reading while riding the trails.
Summary: I am very disappointed in the Magellan eXplorist 710 and returning it for a refund. Took it with me on Nov 4, 2012 for a hike in the Grand Canyon. I had the unit secured in a soft carry pouch on the front strap of my backpack.
Summary: Even after firmware update 6.33 the electronic compass still freezes up. I sent the unit back for a refund and ordered a Garmin Oregon 550T. I liked all of the other features mentioned on the other reviews of the 710 but there should be no glaring bugs in their top of the line unit and the customer...
Summary: It was a toss up between the 710 and the Garmin Quest. Took the Magellan because of the higher resolution maps. Unfortunately had to have it replaced under warranty. Unit would shut down without warning while navigating in the car. No amount of fiddling with the settings helped.
Summary: Nothing jumps out as outstanding. System is slow, touch screen is quirky, and not all that intuitive. GeoCaching downloading is awkward but that may be Geocaching.com - my found caches don't show up as found. My Iphone works better (when I can triangulate with cell coverage).
