[BC] GPS

[Alan Alsobrook]

Mike you totally lost me on this one. It sounds like you are saying that 
you go out to the end of the radial to determine where it is. What I 
think you are really trying to say is that you can plot a "off road" 
route back to the center of the array from the end point. While that is 
true it's a bit cumbersome in most situations.

If that's what you are saying I am able to do the same thing before I 
leave the shop by laying out the array and defining an "Off Road" route 
and loading it into the GPS, with the start point at the far end of the 
radial and the destination being the center of the array. Then you can 
call up the route for the radial you are running and have the route line 
on the screen as you are working your way out, or back in, on each radial.

With the proper data fields displayed you can have your distance to 
final, (the array center) current location, current time, you can throw 
bearing up (it should be exactly 180 deg out from your radial), and 
anything else you like.

Now I might add that I use a GPS-V portable, and I also use a Garmin 
2610 in the vehicle attached to the laptop for navigation and mapping, 
via topo quads.
