Ask a Question
  • Are u an Australian company

    Hi, We proudly are. We are based in Adelaide.

  • Hi.. Is the technetics delta 4000 waterproof? Does it cone with wireless headset?


    Yes the coil and shaft are waterproof,  only the control box isn't. But for shallow water detecting it works a treat.

    As for headphones, Teknetics don't make wireless headphones at this stage but we do jave their wired headphones available which are very comfy and make hearing ultra faint signals so much easier.

    If you have any questions just let us know.
