Turn on your ProPointer. Wait for the two beeps.
Take a convenient piece of metal. Doesn't matter what type or shape... Some people use a washer, a coin, or a ring.
Use what ever you find most convenient.
Place it against the body of the ProPointer. Start between the battery cap and the speaker holes.
Slide it towards the tip slowly until the ProPointer starts to chirp, then pull it back a touch so it's silent again.
Hold it at that spot and scan for your target. Try not to move the piece of metal while searching.
That should give you an extra couple inches. A quarter that normally triggers it at about 1.5" now triggers at about 3.5".
The way it works is you bring the ProPointer right to it's threshold. Then it takes much less to trip it.
Another thing you can do is 'detune'... Basically the opposite. You can set the threshold back from the edge, making it harder to trip.
By detuning you can make it so the ProPointer won't trip until you're right on top of your target.
Reduce the sensitivity by placing the convenient piece of metal against the side of the ProPointer between the
power button and the shaft. Then turn it on and wait for the two beeps. Remove the piece of metal. Test the
sensitivity with the piece of metal to be sure it's not TOO detuned.
If it is, start over... But place the metal a little further back. Turn it on, remove the metal, and test again.
Once you find your sweet spot, try and memorize where to place the metal, or better yet, mark it with a dot of paint.
I actually detune more often than supertune.
