This is the original coil that the XP deus came out with when it was launched.
The 9 Inch coil is the one that is mostly widely used in the field. It is a coin and relic coil and with frequencies between 4 and 18khz. It is a superb all round coil if you are mainly a coin shooter and relic hunter.
The coil is FAST and separates trash from treasure Better than any other Detector. It excels in trashy sites whether they modern high conductive trash or the older iron infested sites.
With Practice this coil will allow you to cherry pick the trashiest park with ease and is so light you can swing it all day long with literally no fatigue.
RECOMMENDATION: This is the coil to choose if your a coinshooter that likes to hunt the very trashy areas, It is what I would call the SPECIALIST Coin and relic coil for the XP deus.
Go this way if you are looking for a specialist coin and relic Killer that will cover you in 99.9% of cases, Including the beach. Not the most effective Saltwater wet sand hunter but nowhere near the worst either.
