Break out some of your kid's inheritance and get you a Terrova I-pilot and HB GPS/Down Image unit AND A FLASHLIGHT. I'm hearing good things about the Helix.

Your luck sounds like mine, Russ. I learned some time back to take a can of red spray paint and liberally paint the positive end of my batteries as soon as I buy them. I had too many snow goose electronic call boxes go up in smoke when folks hooked the polarities up backwards.
