Coil Testing at the beach

Thought this info may be helpful,a variety of coils in dry sand using ball sinkers as targets.Results are in INCHES!


A couple of notes regarding these tests
The tests were done using a GP3000 in normal mode.The * is in deep mode.**means signal was difficult to discern.
The monos gave a notably sharper response
The quietest coil was the 10x5DD,next the 14DD and the 14x9.
The NF 14x9 was tested on a GPX4500
Smaller coils exhibited less EMI
The 10x5DD may perform well in mono on very small targets however my smallest was 1 gram,results were poor on the larger targets.

Excellent work, all very interesting.
Thanks

I just brought the NF 14x9 elliptical , interesting to see it performed well in your tests.... good stuff

well done, nice test bit of food for thought . Thanks for sharing!
