GPS is great, remember the basics
Hi there,
I was resistant for a long time to the gadgetry of GPS/Computers, but have since found a use for them and now encourage others to get into the field as well. Here are some things that may be helpful;
1.) the color models are awesome and help in distinguishing national park lands, etc. Also 'sunlight readable LCD' screen (very cool, saves battery)
2.) I use an eTrex legend C (c for color) and it is GREAT. I chose it over the vista c (built in compass) because mine gets 36 hours battery life over the vista's 12 to 18.
3.) I have used mine on lakes and rivers, deep mountain valleys, in the rain, at night, and on road trips. Rarely does it fail to gain a signal, although it does take a minute if its been off for awhile.
4.) When letting it access signal stand still and give it open air, then you can move or get inside or whatever.
5.) BUY THE HANDHELD solar chargers on Ebay and get AA NiMh batteries. This way you can stay in the field indefinitely and never run out of battery power!
6.) Always keep back up navigation aids; map and compass, knowledge of terrain, etc. EQ failure is always possible, loss, damage (although they are tough), or EMP blast
7.) I love the rhino units that beam positions to other friendlies with same unit, but battery power is less....the transmitter GPS (walkie talkie) also seem cool, but that's a bummer if something happens to it, now you lost comm and nav
8.) Using in tandem with computer is great too. I recommend the National Geographic Backwoods Explorer topo software. For about $50 you have the whole US in detailed topo format, AND you can convert the screen easily into a 3D flyover for scouting terrain via virtual 'helicopter' or re-ride your motorcycle trip
9.) Radio comms to friend can allow for great lightless, night rendezvous even without fancy rhino 'beaming technology', just transmit coordinates on semisecure channel, or use a scrambled code of some sort.
Well I hope that helps some. It does take time and practice to learn to use, and buying the software from the company to download maps into the unit itself is really imperative! That's an expense I didnt consider at first. The raw basemap is pretty lame.
Good luck!
