Garmin is far and away the best GPS product out there. I have used Garmin for many years starting with a 12XL that even though it way out dated still has some features I like that the new ones don't have. I have a MAP 76CS which has the TOPO maps on a micro SD card that I trade out with an Inland waterways card in the summer for boating.
You can't go wrong with Garmin.
If your to busy to go hunting, your just to busy.
