DigsAlot Posted March 21, 2018 Author Share Posted March 21, 2018 I think the 14 x 9 and the Sadie are going to be my coils that I use the most. Thanks for the info gents. 3 Link to comment Share on other sites More sharing options...
schiara Posted March 23, 2018 Share Posted March 23, 2018 I would highly recommend Doc’s Gold Screamer Power Pack, Li-Ion Battery System for Minelab PI’s, Although they are pricey, its worth it. https://www.robsdetectors.com/docs-gold-screamer-power-pack/ 3 Link to comment Share on other sites More sharing options...

DigsAlot Posted March 30, 2018 Author Share Posted March 30, 2018 So I plan to go out with the GP 3500 this weekend, wondering if anyone had some good settings for small shallow gold in the northern nv type soil? Perhaps Steve lol Link to comment Share on other sites More sharing options...
PhaseTech Posted April 2, 2018 Share Posted April 2, 2018 Here's what worked for me when I was swinging a 3500. These settings will work equally well with small - medium mono coils and the stock DD coil. Set your controls to the following settings: Signal control - just off maximum (in noisy environments you may need to turn it down to 2 o'clock) Tone - the highest setting you are comfortable with. My preference was 3-4 o'clock Volume - 4 o'clock Threshold - just audible, but smooth - if it is breaking up it is too low Coil - Mono Soil - Sensitive Ground - Fixed If the ground allows it you can use Deep boost, but if it upsets the stability of the threshold, use Normal. Ground Balance as often as practical, and avoid running in Tracking if at all possible. Perform an Auto Tune as often as necessary. The most important aspect to the tuning process is to ensure the coil is held motionless. The easiest method I find is to turn the coil at 90 deg. and find the loudest direction of interference, and then place the whole detector on the ground, with the coil still vertical. With the GP 3500, you can keep the detector tuned by using the Manual Tune control. When you get a faint signal that you suspect may be a small nugget, play with the audio controls and see if a few small tweaks improve the signal response. 2 1 Link to comment Share on other sites More sharing options...
Northeast Posted April 2, 2018 Share Posted April 2, 2018 Hi Nenad. I don't have a 3500 and am unlikely to ever but one thing stood out in the bit I read above. 13 minutes ago, PhaseTech said: Ground Balance as often as practical, and avoid running in Tracking if at all possible. I often see that Minelab tracking has been heralded as being pretty awesome. Not so with the earlier models such as the 3500? About when did tracking really step up to the plate?

PhaseTech Posted April 10, 2018 Share Posted April 10, 2018 The tracking has always been good, it is just the danger of tracking out a target is always greater when using a mono coil. Small low conductive targets, and the higher the mineralisation, the greater the risk! On the SD2200 series, the tracking was a slower rate, and as the 2200 hates mono coils (except for really mild ground) most people never took it out of tracking. On the GP extreme and 3000 it was a faster rate, I guess it had to be because the machines were more sensitive. The Level adjust allowed the user to control the tracking to some extent, but most found this confusing, so 3 x speeds were introduced on the 3500 (with the Level Adjust being pre-set). Using a DD coil, I have never had a nugget track out (that I've noticed), but have noticed several times using a Mono. Not instantaneous, maybe 5-7 sweeps and the target was totally gone. Re-balance off to the side, check again, and yep target still there. Dig it up, and sure enough it's gold. This is reduced with the slower tracking speeds, but the only way to remove the risk all-together is to use Fixed and re-balance as often as you can remember. 2 Link to comment Share on other sites More sharing options...
Northeast Posted April 10, 2018 Share Posted April 10, 2018 Thanks for the response Nenad. I'll probably never own anything from that line up of detectors but interesting to know and hopefully helps somebody who does/is looking to use them. Thanks again.
