I dont know about other V3 owners but i wish there were a detail manual,,,Dont get me wrong it points you in the wright direction...Now the manual for the DFX i find is more detail in information on each adjustment....Is there a book out on the V3 yet ??????Dont get wrong i love my V3 but i want to get the best performance i can and the only was to do that is by adjusting the detector to the spot your hunting or the type of targets your looking for....
