Re: coils hammerhead

Most people make circular for simplicity. Squaring it up does not change the inductance much, but I believe it will reduce depth. A good all-purpose coil size is 10-12 inches (25-30 cm).

I´m building the HH and need to know from you guys....which coil is best for beach hunting mainly wet sand(wading)..., i´m thinking about a mono coil...but using one from the Sand Shark or Hunter Mark II, at the same time would like to try a DD from a Infinium.
Could you post here some picts. for a real good one for the HH...thanks in advance !
