When turned on they'll pretty much all interfere with the GPX. That shouldn't be an issue really as your coil should be away from the hole anyway unless you like digging to the sound of your pick being detectedHarryHoudini said:Umm very interesting vids.
It should not be this hard to buy a pin pointer that plays well with the GPX and does what it is built for : pin point gold.
I would like to have something that does not false frequently. It should not be this hard
The problem lies with the ones that interfere while turned off. I was out with a fairly new to detecting mate & went to check how he was going. He complained that he thought the coil was playing up & he couldn't settle the detector down no matter what he tried. I spotted the pinpointer on his belt & said show me that. He laughed & said it won't be that they said it won't react with the GPX. I put it behind my back & his detector immediately quieted down. I then moved it around in front of me & you could hear it react again with the GPX immediately. It was turned off! I can't remember now if it was a Garrett original type or the Minelab one but it was one of the two.
I never bothered with a pinpointer with the GPX after that but the choices were limited compared to now. I do use one with the GPZ but wear it on the back of my harness belt & it doesn't seem to have any effect except when turned on. It was the cheapest one I could find (Mars) but like other more expensive ones I've owned (Garrett & Minelab) is prone to falsing on some ground. Other than that it seems to work ok for what I want but I rarely use it.
