Vallon vmh3cs audio question

Post by RobD » Thu Jul 26, 2018 11:36 am

I used to detect about 40 yrs ago with a self-made detector, and am re-engaging with the hobby. I shall be in an area in South Africa with iron-rich soil and rocks and I am attracted to a 2nd-hand Vallon vmh3cs ex-Army detector, partly for their rugged construction and the fact that they can be quickly adjusted to mineral rich soil. However: I am worried about the earphone output which is a 6-pin socket to a military-type head piece; so perhaps I'd like to adapt it to a simple ear piece.
Vallon will sell me an adapter for 134 Euros, but that is roughly what I hope to pay for the whole kit - so my question to the forum is this:
Would I be able to source or make up an ear-piece adapter myself? I have an avometer to test which of the 6 pins is live.
many thanks

Hi Rob

Interesting question... I know that some of the units sold to the civilian sector are supplied with a single earphone set. The operator must have one ear free to communicate. The 6 pin connector/adapter could likely be made up for you by a competent shop or individual.

Personally, I would just try the earset supplied & take it from there. Mods on that set would be my first choice. Let us know how you find the Pulse machine mate.

I have sent you a Private Message with some info that is likely to be useful.

For everyone else:
There's a website called "Geotech1 dot com", which has some interesting articles about understanding/building metal detectors, and there's also a discussion forum, which I'm not allowed to link to. On the forum, there is a long thread about the Vallon, it's operation, modifying it, making new coils for it, with significant input from Eric Foster.
