I am making an attempt to build my own Sunray X-1 probe for my Minelab Explorer XS. I don't have one to compare to so I'm working off of images and data I scrounged from the internet.
Here is a video of my first test after winding and nulling. Not in an enclosure yet.

Newbie question: pinpointer coil for surf pi?
Wanted to get the inductance right, and know I can make a simple wound coil of magnet wire for a search coil using the coil calculators, but I want to wrap around a soft iron ferrite rod. Is there a different calculation for that? Could I just use a couple fixed inductors at the right total inductance...
