Well I picked up my new Ace250 from Kelly-co and have been able to use it for several days. I must say Kellyco really treated me right and was really helpful. I bought this for my wife but I really like it. I find that it is very accurate on depth, and what kind of coin it is. It is easy to learn and the pinpointing is on the button. The only problem I find is that after a rain, the depth and type of coin get a little unclear. Has anybody else run into this problem. I recently bought a $1000 machine and this runs pretty close to this one. I think the big difference is with the pricey one I can make adjustments after a rain or in mineralized ground. Does rain or ground moisture make a difference in readings? Tell me what you think.
