Some have complanied that the no motion goes nuts, and is like riding a bull at the rodeo , well Iam still learning thigs I would not recomend it for pinpointing but for relick hunting , But it needs to be properly ground balanced from what i can tell , if its ground balanced in the negitive and you switch from threshold to NO MO with the coil on the ground and then lift it it will sound off, it must be responding to the negitive ground balance you can press retune or just make shure the coil is off the ground when you switch it over I had no probem going form disc to no - motion but only from threshold to no motion.. if it is positive and you switch over to no motion with the coil on the ground its de tuned and you will not get any depth if you lift it in air and put it in no motion and lower it to the ground it sounds off so it need to be netral or slightly negitive in my experiance so far hope this video helps [video]http://www.youtube.com/watch?v=0lVrjcWQe40&list=UUjtTA1ZSEXhfWtQ12CPzXnA&index=1[/video]
