Thanks KAC for your very interesting reply. Smaller coils are expected to give better target separation, at the cost of depth; what is your experience in regard of this aspect (depth loss) ? I ask this because the Nokta Makro 5"x9.5" coil you used, is reported on Nokta Makro catalog as providing good depth. Regarding the usage of different coils, I had the opportunity to use the Mars Discovery (13") coil with my MMK: it got about 2" more depth for coin sized targets, in my soil (quite mild one). I would like to perform also a target separation comparison with respect to the standard coil, because it can be adversely affected by the usage of bigger coils. I wonder if a "standard setup" for target separation test has ever been defined; if so, separation test results could be comparable between different machines, coils etc. Is anybody aware of a "standard" separation test setup ? Any info would be appreciated...

Hi, it would be helpful to know in you experience if there are on the market coils with better peformance for specific applications (e.g park, field, nuggets...)
