Number one ... those are great detectors 2. You must learn to set the threshold with the little pod on front , 3 do not run 6 a whole lot of dis because it has a bunch sorta built in 4 Tune the detector in All metal , set your threshold to a light hum , 5 Ground Balance ...you can find that on youtube , all Tesoros grounnd balamce about the same no matter what year or model , I hunt in All metal until I fimd a target then I switch to DISC ...to check it ....The detector is old but they work grear , I own a whole bumch of Tesors and like these Bandido machines ...... remember set thresshold , set ground balance . set DISC low , hunt in all metal , switch to disc when you get a target
