on foot, though, you should consider a higher end Garmen ETrex or equivalent. the models with the microSD card are nice, and you can use the SD card to install the OSM Garmin maps that Dave Hansen derives from the Lambertus maps. the ETrex takes conventional batteries, so you can use rechargeable NiMH batteries and just swap if they run down. richard
