GPSMAP 76CSx Portable Navigator is one of Garmin's most popular models for outdoor and marine use. It features a new, highly sensitive GPS receiver that acquires satellites faster and lets users track their location in challenging conditions, such as heavy foliage or deep canyons and a removable microSD card for detailed mapping memory. It also incorporates a barometric altimeter for extremely accurate elevation data and an electronic compass that displays an accurate heading while standing still. It floats when dropped in the water.

Comments about Garmin Garmin GPSMAP 76CSx Portable Navigator:
I use this primarily for boating and kayaking. I have Nuvis for the autos and the software mixes well with the Garmin line. Its good for recording speed over water when sailing or riding a PWC.
