Slim-Line Speaker to work with all DOC’s Goldscreamer Power Pack Battery systems or Coiltek Pocket Rocket systems. Can be used on all Minelab Pulse Induction metal detectors from the SD, GP and new GPX series.
This Slim-Line external speaker does require an external amplifier (such as the Goldscreamer Signal Enhancer) if you’re using it on the SD, GP or GPX series.
The Slim-Line works great on the GPX 4500, GPX 4800 and newest GPX5000. These detectors have a built in signal enhance with the stock Minelab battery and do not require an external signal enhancer.
The Slim-Line speaker has a heavy duty clip on the back, which allows the user to mount the speaker to the detectors control box cover, arm cover, backpack, harness or even a belt.
