$1 GPX 6000 Twisting Shaft Solution - O-rings


Recommended Posts

Here’s a simple fix for the 6000 twisting shaft issue- just put a 1/8th inch thick dry O-Ring inside each of the locking rings. When you twist the locking rings, the o-rings compresses and tightens up between the shaft locking ring and collet keeping  the shaft sections from spinning as easily.

I used these two sized o-rings (in inches):

13/16 x 1-1/16 x 1/8

3/4 x 1 x 1/8

Fully unscrew each plastic locking ring and separate each rod, leaving the plastic locking rings in place on them and put the o-rings on. Be sure the o-rings fit snuggly but not too tight around each rod as shown below. Then insert the rods back in place and reconnect the threaded locking rings with the o-rings between the two parts. The o-rings will slip between the plastic collets and the ring wall as you screw on the locking ring. When the locking ring gets hand-tight, the o-rings will provide more locking force between the rod sections so they can’t spin as easily.

Thanks, great simple solution, maybe the Minelab engineers could learn a thing or two from this, they could hand out free little packs of O-rings to GPX customers via their dealers 🙂

Bang up some photos if you can, it gives a better idea of what you've done for everyone.

Or maybe instead of handing out O rings and ferrites after the fact they could properly test their machines prior to release so we’re not band aiding our detectors as unpaid beta testers 🤔

Have lots of O rings will give it a try. Was wondering if the testers mentioned the twisting shafts to Minelab and they just ignored?

No idea if the testers mentioned it or even if they thought it was a reportable issue, I’m sure they would have noticed it though.

As far as getting the O-rings to work, you have to tighten up the lock ring pretty much hand tight to get the o-rings to engage between the two parts to work. It’s a simple fix to try…
