The locator can be used in flooded areas – just keep the electronic unit (“can”) out of the water.
Snow poses no problem. Thrust the locator into the snow as deep as necessary to locate the target, up to the base of the “can”.
You can often trace barbed wire (from old fence lines) buried just beneath the surface. Even if the wire is only a trail of rust it can still be detected near the surface. Tip the locator a little lower than usual – but not parallel with the ground.
First, examine trees for benchmarks and bits of embedded barbed wire. Then hold the locator parallel with the direction of the wire.
