  • Detector Housing

    Just finished my detector a Bandido II µMAX

    Thoughts now turn to the housing. Can't find one I like so will be fabricating one out of fiberglass along the lines of the original. Seems sensible as making a rain cover is then easy.


    My Bandido seems very susceptible to interference

    Would I be better lining the case with foil or would conductive graphite paint work just as well (400-500 ohms per square)

    Is it a good idea to have some kind of ventilation holes so any condensation can escape or keep it as water tight as possible

    Potentiometers and switches. Should they all be tied to a common ground. (the multi turn ground balance I can't do as its a plastic case).

    Hi Koala, I like the low resistance of foil and have used .001" copper foil and durability is good. Some of the spray-on metallics may be good too but I have not used them and durability may be an issue. However I see equipment that uses spray-on for the same purposes and it appears to do the job.

    I think graphite will not be as effective as a full metallic shield and particularly at the higher resistances will be less effective. Also it is more difficult to get good durable connections to graphite.

    My Chance PI definitely performs much better with its aluminum case closed up tight. When open it is noticeably more unstable with some random audio/VDI responses to interference.

    Good Luck,

    Dan

      Thanks for the input Dan. I was edging towards the foil have seen the spray on stuff used an a Delta Pulse.


      SGS it was the control box housing I am after. Looked through the rest of the Mikron Website. The control box on the NRG-150 looks familiar think there were some knocking around a few years ago. Looks ideal if the size is right. Wounder where I could buy one. There was some in the buy and sell on here but no longer sold.
