I carry the little Garmin Geko 301 GPS unit mainly as a backup to the map and compass and partly to allow me to note any tricky-to-find wild camp sites. It’s very light at 87gms so I don’t begrudge the weight too much.
However the screen looks like it would be very easy to break and the on/off button very easy to accidentally press. Especially since I keep it in a silnylon stuffsac on the outside of the pack along with other things that I want to-hand like sunglasses and torch.
|So I’ve constructed a very simple and very light “GPS cozy” from some duck tape, a little bit of foam sleeping mat and the side of a plastic bottle. It only weighs 14gms.|
The plastic bottle is one of those square-sided Finish Dishwasher Cleaner containers. It’s purpose is partly to add more protection for the screen but mainly it’s to stop the foam being compressed into the on/off button thereby accidentally switching the unit on. Without the hard plastic to protect that button, it doesn’t take a great deal of pressure on the outside of the cozy to activate the switch.
There’s also a chamfer cut along the front edge of the foam where the buttons first contact it as the Geko is slid inside. It’s the same principle as used on any door catch, a chamfer on the catch lets it slide back inside the door, only to pop back out once the door is closed.
It might not be the slickest design ever but it’s very functional and has been shaken around in the pack for nearly two years now and is still in one piece. I’ve used the same technique to make a camera lens cozy that’s also worked rather well. Especially when I managed to drop the lens…
