From Manufacturer - Truly a small wonder, the eTrex takes the best features of a 12 parallel channel GPS receiver and put them into a six ounce package that is only four inches high and two inches wide. The result is a unit that will literally fit in the palm of your hand.
Garmin part number: 010-00190-00 has been discontinued by the manufacturer and replaced by high sensitivity one 010-00631-00.
