Great for clearing a flat area after initially getting a signal. Good for hooking dirt out of a hole and also helps in quickly filling in a hole. Really useful when skidding with a large coil - makes it easy to clear a large flat area quickly to get the skid into. I was surprised at its weight. Still effective in most circumstances in spite of its light weight.
Magnet works well.
Glued into drilled hole in end of handle, so won't come out. Rounded end of magnet makes it easy to pull ironstone pebbles and trash off it. Able to easily stand the pick upright while putting it aside and detecting a hole. Saves bending down to pick it up off the ground each time. The Estwing hoepick is good, but too bloody heavy, and too narrow on the blade end, as you say.
