to be complete I use sea hunter markii coil.
It has two coils inside I use one for tx and the other one for rx it is an excellent coil.

The Garrett Sea Hunter MkII coils have very low inductance values. I measured the TX and RX loops in the 8" coil as being around 110uH, and 120uH for the 14" x 10" coil.

no matter of the low inductance it is working very good

14" x 10" this one I am using
