Summary: Three hundred something dollars. This was my first GPS, so I wanted a good one. I thought it would be out-of-the-box great GPS-ing for my Scouts and me. I thought I could track my route from home to work. I thought I could at least get it to tell me how fast I was walking or driving. Nope. So before you run out an buy one of these, let me go through my learning curve for you.
Summary: I bought this one after using my Explorist 110 for over a year. I have purposely held off on writing this up so I can get some time with it. The unit is larger and heavier than the 110. The screen is much larger, but since you mainly focus on where you are and the immediate surroundings, it doesn't seem to matter. Just like the 110, the full manual is on line and you are a fool if you don't download it.
Summary: It is a great GPSr, although complex. it takes some time to learn how it all operates. It interfaces with a PC much easier than my old Maridian Gold, dounloading Geocaches is a snap. Battery life with regular alkaline's is not real good.
Summary: Best GPS receiver in this price range. Comes with 24K-scale topo maps for all of USA as part of purchase price. Don't need to buy maps on SC card as in Garmin eTrex 20 or 30. Touchscreen is a little fussy -- not quite as smooth as iPhone's.
Summary: The 610 being oval shaped does not fit well in the pocket. It fails to aquire a satalite location as quickly as the three other Magellan devices that I own. However the 610 is loaded with features and fits well in the hand.
Summary: Finally got the opportunity to take this unit out on a real hike. I have had this gps since August 2011. One of the things I paid particular attention to was battery life. A pair of alkaline batteries (generic brand) lasted about 10 hours. I frequently checked it, took a few photos with it, one voice memo. I would say 1/3 the functioning time (3 hours) was in suspend mode. The performance of the unit was flawless.
