Got permission to hit a spot I wanted to hunt for 45 years. Clay, ground a rock...Jabbo saying use the C/S coil and surface hunt, come back with the deeper brown coil after it rains. I have until cold weather. A very active private property used since 1922.... Going to get new batteries for the Vaquero, these, while still good , have been in for three years. Might as well get a new battery for the Pro pointer.. I hope it is a knee walking site....
