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. Pictures below.

Some have asked if I make them for sale. Sorry to say, cost wise for parts is expensive here in Canada when shipping, Customs fees from the supplier is factored in. Then add labor. For what they would have to sell for that people would pay. There's really no profit. Then shipping from Canada is also expensive.   You can make one yourself.  Pin out is the same for the Kruzer, Anfibio and Simplex.

Hi Seven, you think this would work on the Vanquish? I just got one today and it has rained all day. I would like to try this on it. Mine is the 440, not with wireless headphones. I may not like it, if not, it will go down the road. Thanks  Dean

Will only work if you know the pinout of the Vanquish and wire it accordingly.

      Testing all three on some deep targets...

      I have loved my simplex, and been using it almost every day since I got it. Also finaly finding gold ( now that I know what I'm watching for. I'll post pictures eventually).
      Anyway I was thinking to myself, how could they make a second generation simplex better? I know it's a ways off, but I bet nokta has already been thinking about this. So I wanted to start a thread about features you'd like to see on the next one?
      I'll start. When night hunting, the light on the back seems to be either not quite bright enough, or it's at the wrong angle, and can't use it well to dig. No problem, I've got a headlight. 
      What if on the next one, they had a sensor that felt the detector be laid down, and switched on a brighter higher angle set of lights to illuminate your digging when in night mode?
      Also multi frequency would be killer, even if it had to be a super simple featureless dumbed down machine, at least around here.
