washgravel said:Here is something to think about when I tested my Minelab Pro Find Pinpointer.
After switching on the PP and setting it to its highest 5 sensitivity setting I can get 50mm on a 5c coin from the tip of the PP in an air test.
Then I try to lay the PP horizontally on mineralised ground but it sounds off and reacts to the ground making it impossible to do another test.
So I switch the PP off and with it still at its highest 5 setting and still lying on the ground I restart the PP and now there is no more reaction to the ground.
I then test the 5c coin from the tip of the PP and I again get 50mm however when I lift the PP off the ground and do the another test on the 5c coin I only get 25mm.
Okay AngerManagement by placing my ML PP against the ground before switching it on I am doing a Ground Balance.
I always thought you get less depth once a detector (Pinpointer in this case) is Ground Balanced to what it achieved in an Air Test.
