..does anyone here have any experience w/this combo ? I recently recieved an Excelerator II Pro in a trade but I'm afraid it is bad. I tried it out for the first time but I couldn't get any solid signals so I tried to test a quarter sitting on a piece of clean ground and could barely get it to give a decent signal and inaccurate ID at 6". I tried different modes, sensitivities etc. Ground in the low 60's. The audio was stable and there was no serious EMI in the area so I can't think of any outside factors influencing the coils performance. I do know that they respond best to medium and large deep targets but even so I can't believe that my test results are even close to normal. I also realize that manufacturers claims have to be taken w/a grain of salt but it's nowhere near what they say it's capable of either. Any shared experiences would be greatly appreciated...
