Fairly new to the tesoro world. My golden has arrived but the hardware to connect the coil was missing, so I wait. Anyway, I always keep a detector in each vehicle. We just bought a new camper so I would like to keep one in there as well. The screens on the ace250, and the f2 aren't the happiest being stored in vehicles in the mn winter (never know when someone will lose something in all that snow). So I thought I would replace them with tesoros. Found a used silver sabre umax for sale locally. Can not find much about them....what is a good price used? He says excellent condition, but I haven't seen it yet ...... ( many times someone else's definition on excellent seems to differ from my own)!
