Hello I just acquired a new ace 250 and went to a friends back yard to try it out.Did what the manual told me but with the senstivity set at 4 or 5 all the machine did bas bong bong bong steadilly as I passed it along the ground.Now I know there is plenty of junk in his yard but how in the world will I find coins and jewelery. So I then decided to lower the sensitivity to 2 and that was better.Do I have an over sensitive machine or are they all like this?
