Hello, I'm getting back into caching since busyness took me away for a few years... A couple years back I sold my gps (garmin map60cs) and bought a emprum utilimate GPS plugin for my iphone. I read nothing but amazing reviews on it, so I purchased it! I love it, combined with the Gaia GPS app it has been amazing for my deep backcountry backpacking/snowshoeing trips... I used it last weekend to find some caches and it preformed great. I was just curious if anyone in the caching world uses this, or what peoples opinion is on this, or just a general discussion on plug in GPS devices for iPhones.
