Today I had the chance to test out the new Detech Ultimate 13 coil, manufactured for White's Electronics. Yes, there is already a Detech 13" coil on the market, but this one is new & improved and was made in a collaboration with White's.
Now you may be thinking exactly what I was... that 13 inches is a big coil.
My concern was that the footprint was going to be too large for the small, private yards that I hunt.
With the new technology, referred to as DD or SEF, these coils are supposed to have great separation and still maintain significant depth.
So I returned to one of my old sites, where I'd already pulled out about 50 old coins using various coils and worked it pretty hard. At the end of last season, it was hard to squeeze out another target at this site, so I figured it would be a great spot to test out this coil.
