This is the just a test i did just to show the difference changing frequencies makes

On the Minelab Manticore, i will be doing something similar for all the detectors i test in the future.

Below are 82 targets, 3 different coils, all on the same settings i use.

 

It's all based on what i would i dig or not dig, most detectorists would not dig some of the signals i get, that's where the video will come in useful.

The 'criteria' is just what i am basing the Yes (1) No (0) results on. 

 

just the 9'' coil tested up until now (See below)
