oBuy and install an Invisible Shield screen protector ASAP.

oCarry spare batteries.

oCarry a compass with adjustable declination and a good paper topo map of the area - and know how to use them and the GPS together.

oCarry a UTM grid and know how to use it with your paper map to convert a GPS coordinate to a location on your paper map, and vise vera. See http://www.maptools.com for details.

oPre-load as many waypoints in your GPS as possible before heading out. I use geobuddy from http://www.geobuddy.com.

oMake sure you set the GPS datum to match your map. Common mistake!

oCarry a small notepad or folded paper, and a pen to take notes (see next suggestion).

oDon't bother creating waypoint names while traveling - just use the default codes and jot down a note defining the respective codes. Change the waypoint names later when you have more time at home or in camp. Use the same notepad to take notes on your trail.

oDon't leave your GPS on all the time unless you specifically want to capture a track for your travel route - instead stop frequently to turn on the GPS and capture key waypoints or to get bearings.

oCapture waypoints often - no such thing as too often. Make sure you create a waypoint for your car location and campsites.

oThe #1 rule of navigation is to never lose track of where you are - Ever. Always keep track of your current location on your paper map.

oCarry your GPS & compass with you when wondering away from camp. Lots of stories of folks who have problems finding their camp in dim evening light.

oAssume your GPS is water resistant, but NOT waterproof - lots of stories of leaking cases. Consider getting an Aquapac case if on water.

oLots of folks add an external antenna and then put the anetnna on top of hats or packpacks if leaving GPS on. A top shirt pocket may work for some. I myself don't leave it on.

oBe prepared!
