Received my first PID from Hatch this weekend. Waited until todays warm 38 degrees to go out in the garage and set up the auto tune. Hatch’s instruction are to the point and easy to follow. It took about 2 hours for the PID to get with ONE DEGREE and set it. This device is terrific. Now I have to wait another 3-4 days for the “last” snow storm of the season to pass so I can cast a bunch of 45-270SAA. I can’t speak highly enough of the quality of this device and Hatch’s patience with my poor ordering skills. Thanks, Hatch!
