I headed out today to search a house I was given permission to hunt and when I arrived my Eagle II SL wouldn't power on.I tried both battery packs to no avail.Took it apart and checked for a possible plug that came loose but nothing.I must note...before I left I tapped on the detector where the battery pack goes to get the coil shaft to go up farther.This machine has worked fine up till now.PLEASE PLEASE PLEASE HELP!!!!
