GQ GMC-320 Geiger counter UPGRADE mod. Detached PROBE! [CAPTIONS ENABLED]

Ever wish you could have a nice DETACHED probe like on all them fancy-schmancy snobby Geigers like the LUDLUM 3 and others without spending all that cash?
Well heck, YOU CAN!

This video shows how I modified my common "starter" Geiger counter model GMC-320 to have a versatile, sensitive, and easy to use EXTERNAL PROBE.

Here I show how I used a regular telephone cord and jack (an RJ9 jack) to easily and conveniently set this mod up!
