This kind of a GPS receiver is a good compromise for vehicle use as well as hiking/paddling/biking, etc. For this particular mount, I used the Magellan swivel cradle mounted on a custom sheet metal platform, which also serves as the mounting location for one of the clinometers. (The other clinometer is located HERE) I used a circular rubber gasket from the hardware store between the rotating cradle and the fixed base to eliminate any rattling from the mount.
