I'm a bit puzzled on timings, I've pretty much left mine in sensitive extra since getting it and it seems the go-to timing for around here. I only use mono coils and I'm basically chasing tiny gold in soils with very low mineralisation, 1 gram is huge for me so we are talking 0.0X to 0.3 gram bits on average that I am chasing. I was looking at timings charts on this site here and found the two best options for me below, I think. Sharp appears to be best if using a DD, does that mean I'd be best off sticking with my sensitive extra seeing I use a mono coil or is a DD coil worth considering?
I'm trying to see if there is a way I can scratch out a bit more depth on these little nuggets.
This chart is the one that throws me out the most, basically no timings are "Excellent" for mono coils except Fine Gold, Enhance and Sens Smooth which are more for mineralised soils, only DD coils seem to have Excellent for the timings I'm trying to use for the small gold in mild soils..... 😕
And this chart below describes the two timings I think might be best for me.
As many GPX owners may know the GPX has toggle switches, they're quick and easy to use, but they're also quick and easy to bump... you can spend half a day detecting in a mode you didn't mean to by accident unless you check them regularly. It's happened to me all too often.
I have a Steelphase SP01 audio enhancer for my GPX and on it's toggle switch is a handy little guard that stops you bumping it's on/off switch.
I've decided I want to add something like this to my GPX to prevent me screwing up bumping the switches but I can't find where to buy them, I'll have to keep hunting around online and see, and also check electronics shops next time I'm in town.
Has anyone done something like this to their GPX or am I the only clumsy one bumping the switches all the time? If so what switch guards were best? There appears to be a lot of different designs.
GPX 4500. Been detecting for a while in the hills in California (Sierras) where I got started in 1970 ish with my White 5000 D I purchased from Jimmy Sierra at his shop in San Rafael. We’re still in touch although he says he doesn’t get out anymore but loves to read about others adventures.
then moved to New Mexico. I decided recently I needed to try my hand with Minelab and purchased the GPX 4500. I’m finding it difficult to find reading material on settings or proper videos. I have a friend that suggested a setting for the area I prospect in. I got a mono Commander and a GP Series coil with it. Hopefully I’ll find good info on this site. 😎
I’ve been hunting a good site using the Deus and Equinox which has nails and small iron mixed in with good targets, some good targets being deep, but near or in the iron. My question is, will a GPX with Iron Discrimination turned up and the smallest DD coil pull out the deeper, non-ferrous items amongst heavy iron? Has anyone had any experience with this? I think for shallow targets the Equinox or Deus works better for shallow targets in this “machine gun iron”, but would like to see what others may have insight on for using the GPX. I’m assuming the fast setting and special soil timing may need to be adjusted as well. Thank you in advance.
I bought this GPX 5000 second-hand and when I first had it it worked fine, but now when I turn it on it doesn't seem to be able to detect any signals. If I wand it over a large piece of metal it just about detects it and if I turned the unit on and off it seems to improve it. Could it be the coil?
I've made a video :
