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. My biggest complaints about this unit are: 1) when searching for an address to set as a destination, the unit will auto fill fields (which is nice for city names etc, but it will only allow 4 number...
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. I would have to stop and find the perfect angle to see it. I wish Magellan would improve that feature because I'm not too happy with Garmin at all and I would go back to Magellan.
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. Backtracking especially is impossible to use in this way. This may be improved somewhat if one would turn off all display options and use the most basic display which I'll have to try. Stay tuned.
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. I descended the South Kaibab Trail to the Colorado River and ascended the Bright Angel Trail back to the South Rim.
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 shouldn't have to be part of the product development team.
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. Unit was also overheating during this time. The jury is still out on the replacement.
Summary: Pros: Camera: Picture quality of the 3.2 megapixel autofocus camera is remarkably good (up to 1600x1200 pixels), the low resolution video camera not so much (video resolution is only 320x240 pixels and playback is rough and jerky) . Photographs are automatically geotagged and can be attached to your notes for the geocache. The photographs and videos can also be viewed on the internal picture viewer.
