Having large hands and long fingers, they get sore and sometimes cramp after a fairly long session of detecting. For a stopgap measure, I wrapped a layer of 1/8" weather stripping around the grip on my at pro. I also removed the Velcro strap from the armrest. (can't understand strapping it on unless under water maybe) and added a layer there. I took it out for a 3 hour hunt, returned with no pain or cramping in my hand. The weather stripping can easily be replaced if it gets soiled, etc... Hope this helps someone else...HH! I would like to adjust the electronics unit up and to the left so I could see the display easier. This would help greatly when pinpointing! Anyone out there tried this?
