Many know I like to tinker with metal detectors and customize them to my personal tastes......So that is what I did to my Simplex. Since it is not the version with the wireless headphones and need to use the supplied wired headphone adapter, a mod was made. The supplied wired headphone adapter is too short, the wire kind of whimpy. Also, did not place the headphone wires in a position that wasn't cumbersome. A much longer adapter was made up, so the headphones can be plugged in by the arm cuff. Now the headphone wire will run up the side of the body. Out of the way. Less chance of snag ups or pulling your headphones off the top off your head when you lay the detector down. Not pictured, when the headphones are plugged in, the wires is secured with a cable tie thru the arm cuff strap slots. I can also go wireless using an aftermarket wireless headphone. I can plug in the transmitter into the adapter jack and place the transmitter in the convenient holder under the armcuff. Very nice set-up. As you can now water hunt, a bit deeper.
