I was just getting on to ask if putting a coil from a different manufacturer on my Tesoro would damage it? I am wondering if I can put a probe coil from my HF pinpointer on my Bandido 2 umax, Outlaw, or Conquistador umax? Does anyone know the specs (frq, inductance)on the HF pinpointer? I dont even know if it is a IB or not. I dont want to damage my detectors, but I want to do some probe coil testing. Thanks
