Quest STP20 Waterproof Search Coil for Scuba Tector Pro

The Quest STP20 search coil gives your Scuba Tector Pro a bigger appetite. Swapping the standard open face head for this 8 inch round waterproof coil widens every sweep and extends your reach into the bottom, so you cover more of the swim zone, the surf line, or the wreck site in the same amount of air and daylight. It is the wide scanning option in the Scuba Tector Pro system: same 95 kHz pulse induction brains, same 200 ft (60 m) capability, more ground covered per pass.

More Coverage Where It Counts

The Scuba Tector Pro's standard head is built for controlled, precise work in tight spaces. The STP20 answers a different question: how do you search a swimming area, a mooring field, or a stretch of beach before your dive time runs out? A 8 inch round footprint sweeps a wider path and reaches deeper into sand and silt, which is exactly what you want when the target is a lost ring somewhere in fifty square meters of bottom rather than a coin in a crevice. The swap is a one time, few minute job: open the battery compartment, loosen the electronics screw, and slide the Scuba Tector Pro's electronics module into the STP20's handle. Add the Quest Rod Extension Kit and the combination becomes a full length beach and shallow water detector with a serious coil at the end of it.
