We use the Montana 600 now for 3 months, mainly for geocaching. Moving from eTrex Legend and eTrex Vista was at the beginning a little bumpy, especially after we unpacked the unit and there was an absolute "force Grumpy" in front of us. How should such a huge part of keeping permanently in his hand, was a little mystery to us. After about a week the Montana had convinced us. For Oregon and Dakota owners old hat, the query processing has been a revelation for us. Always having cache information and spoilers on the device case, which was new territory for us. After we had bought no Oregon us a few years ago (the display was not suitable for us), the Montana could absolutely points right there. You can see everything on the big screen, even in low visibility conditions. The battery lasts for intensive use in any case more than a day. In normal use, the part comes once a week to the electrical outlet, usually for prophylactic charging. The touch screen is simply amazing. Even with thick gloves still operable, both in the snow and in freezing -20 degrees, and in the rain. This would not create a capacitive display - and quite broad-fingered ones can also use input pins (the toothpick to the pen - without the extended mine of course - everything is possible). We have the equipment granted a screen protector and has already proven itself. As AutoNavi we are not yet used. What annoys some and a point deduction brings (although one could argue, however, system software and device belong together for us), is the software that could be a bit more comfortable in some areas. Deleting found geocaches somehow not so easy. Perhaps this is also simply not as long as the GPX file of the query on the device. And that it once acknowledged a memory overload by too many queries with a reset to default, was not so very funny. Since we had an error message and an expected termination of the charging experiment. That's it then but also already. We are currently satisfied with the Montana and would no longer exist at the moment out of my hand.
