All of us seem to like trading Dectectors. I only have one that I won't trade off myself and it is my old Golden Saber II. Maybe Tesoro should try a Monthly fee to in effect rent out their Detectors. Use this monthly fee toward purchase if the user decides to keep it. send it back any time with shipping being charged to the user. If the user decides not to send it back charge his card. I think it would work and I would get to try more detectors, of course I have already owned all the Notch models already but this could be a winner. I would love to try a Golden Umax with a 5 3/4 Coil, especially with the old tones installed.
