In my truck, I have a Garmin Street Pilot - it talks if you want it to. That can be handy; "In-1/4-Mile, Turn-Left ... In-300-Feet-Turn-Left....Turn-Left ... Drive-2.5-Miles-South-on-State-Highway-6-then-keep-left-at-exit". It'll also announce if it loses or picks up satellites, changing the accuracy, it announces if you're off-track, and can be set to announce a given distance, waypoint, or time mark. With WAS enabled, its accurate to within about 3 meters/10 feet. The display is pretty good-sized, VGA resolution, and the onboard mapset can be whatever size you wanna buy the memory and the mapset CDs for. It will interface with a 'puter, which I sometimes do. I have a Garmin E-Trex Legend handheld, and an add-on module for my handheld PC. Of the 3, the E-Trex is the most accurate - within a meter/yard, tighter still if WAS-enabled, and though it has only built-in memory, a large enough topographic mapset can be loaded into it for a good week's worth of hiking/hunting, or, with the appropriate "Fishing Hotspots" mapset, for a week's worth of fishing right where you wanna be. It too will interface with a 'puter, though I've really only done that a couple times, and then just 'cause I could
Somethin' I really use the E-Tex for a lot is markin' where I've parked my truck - whether in the deepwoods or at a shopping center ... real handy to know exactly where you left your transportation, and how to get right back to it :wink:
Now there are combination GMRS Radios/GPS units, Cellphone/GPS units, and combination Fish Finders/GPS Units, but I'm satisfied with the setup I've already got; if I drop one item into the lake, I still have the others
