[QUOTE="XLOOX, post: 631220, member: 16174"] As Adrian says - you can only use a PI with the ground balance off when the ground lets you. Turn the GB on, start at GB=1 & adjust it up until detector is just silent when bobbed up & down from a foot to an inch over the ground ( do not touch ground with coil). Note the GB reading then start at GB=10 & bob coil & turn GB down until just silent & note that reading too. If the 2 numbers are close together then you have no chance of turning GB off. In really hot ground the window can be 0.1. In really mild ground it doesnt matter where you set the GB it will still be stable. Before you get carried away with concern of with the loss in depth with GB on, first get her working [u]with [/u]GB on and see what depth you get. 5ft is more than I ever got with my TDI SL on anything - except maybe a car body. How big a meteorite are you looking for ? [/QUOTE]
