Summary: This is a good unit. The problems it has, is it eats batteries and it is almost impossible to read in the sun. All the features on it are good, accuracy is outstand except for elevation (It can be anywhere from 25 t0 500ft off). Batteries last only about 4 hrs, if your lucky. Make sure you carry a bunch if your going for the day. It does almost all that it advertises it does. The only problems I found are the ones I mentioned.
Summary: What I like: accuracy, screen brightness, touchscreen, camera, quick-disconnect battery door, mini-SD capability. What I don't like: difficult to enter text for a log, touchscreen get wonky sometimes, the weight...very heavy, when synced with Magellan Vantagepoint 1000 random caches from around the world are automatically loaded.
Summary: The firmware that came with it did not work as advertised, it did not keep tracking when it went to sleep. I upgraded the firmware to the latest from the Magellan site and it now works as advertised. My last GPS was a Delorme PN-60. Unfortunately it got crushed when it fell in front of a Jeep. Compared to the PN-60, this has a much larger screen.
Summary: I am writing this as a retired test engineer with a GPS background, so I have time to mess around with my GPS and the experience to understand what I am doing with it. I have owned a Explorist 610 and a 710. My recommendation is that if you are on the fence concerning a outdoor handheld GPS unit you should go with Garmin.
Summary: I purchased this unit as an upgrade to our trusty Explorist GC. Was very disappointed as soon as it booted. The directional arrow is so huge on this thing, it practically covers 1/3 of the viewing area! I inquired at Magellan if there was a way to adjust the size of the arrow and they responded with "no". You have to geocache in the compass mode. The arrow covers all the caches on the screen. I have since returned this unit and purchased a Garmin product.
Summary: I bought this back in Jan of 2011. I like the features but it has some bugs even with firmware updates. Things like random crashes & resets are somewhat common but only to a mild annoyance level. Camera quality is so, so probably a bit less than what you are used to on your cell phone but the geo tagging feature is nice.
Summary: US base map version reviewed. Good points: Base Map US version has most roads & Railroads & RR stations EVEN IN EUROPE! This is a product sweet spot and may be the best for your use. Data base is HUGE and searchable by name for Geographic features in the US. (US version) so you can find the Mt peak or other (waterfall, valley...) by name. (UNLIKE Garmin 76CSx). Waypoints and Tracks are stored in GPX files Native on the machine.
Summary: I've now ordered this 610 three times. Unit 1 arrived and I familiarized myself with the menus and was happy with the operation. I then loaded the software onto my PC (Windows 7 Ultimate 64 bit) and connected the device. Windows immediately warned that it had errors in the file system and offered to "scan and fix (recommended)".
Summary: I thought I did thorough research before buying my Explorist 610. After registering it online, I used it for a couple of weeks before trying to download updates and VantagePoint. I was very sorry to find out that those programs are not Apple compatible and I cannot use my iMac with the Explorist 610. This is my first handheld GPS device and I am impressed with it although still learning how to use it's various functions. Very disappointed about the incompatibility issue.
Summary: i bought gps for when i go walking in the bush,i have not been able to use it because the unit willnot turn on,it will not turn on with bye battery power,it only turn when i pulled into cord on usb on computer,thanks garry.
