Garmin's home page has a comparison chart for all their models; some specifically are for: on foot, water, road and air. I am considering GPSV(foot, road), upgrade from your GPS III(air)(current model is GPSIII Plus, $364). The GPS V has these additional features; 500 way points w/15 character for name and 50 characters for comments and 50/254 automatically calculated turn-by-turn route or manual point-to-point route, better screen resolution(4 level gray scale 256 x 160; GPSIII, B&W 100x64), 3000 tracklog points, WAAS(wide area augmentation system) capability points; hunting/fishing calculator, celestial info page, proximity waypoints and built-in calculator, audible alarms and 25hr battery life(GPSIII, 36hr) Retail $536, 11/25/01.
Garmin also has three models with color LCD screens. GPS12CX, 3 color, $386; Street Pilot Color Map, 16 color LCD(battery life 2.5hr ?) $890. Street PilotIII, 16 color LCD(battery life 2- 20hr) $1272. Color models appear a bit pricy and are more than I would like to spent unless they are worth the difference. K-Mart on line has the Street Pilots @ $700 and $1,000.
As an experienced hands-on user of GPS and its applicable application to finding your subject/comps, would appreciate any additional comments/info you may have, or a particular feature you desire or one you can live without.
Thanks,
