[QUOTE="the duck, post: 2090, member: 138"] Getting extra depth out of a VLF, multifrequency, or PI machine is very difficult, because these machines follow an inverse 6th power law relationship between signal voltage and depth. If everything else is maintained equal, doubling the depth requires 64 times as much signal. If this is done by increasing transmitter power, doubling depth requires 4,096 times as much battery drain. Thats the basic reason why depth increases come so slowly in this industry. from the engineers that build detectors, this must have good batteries [/QUOTE]
