If your new to the hobby, you never experienced the VLF/TR disc detectors we has back in the 70-80's.
You learned to GB your detector, once you learned it, it never left you. I grew up using the Garrett Master Hunter
Deepseeker and Groundhog series. The Scorpion is basically a old circuit design based on the Groundhog with an updated PC
board and smaller housing. When we went prospecting for silver in Northern Canada, we hunted the mine tailings which
were loaded with silver nuggets. Many were pretty small, BB size or smaller. The 15khz Groundhog was the better Garrett to use,
it would pick up those small nuggets.....I believe the problems people are having tuning the Scorp is caused by the
mineralization in the ground. In mild ground the Scorp should be a super detector, in bad ground could be a challenge.
I think the last Groundhog I had air tested a small 1/8" gold nugget at about 3".
One thing you'll notice that all the older VLF/TR Groundhog units get snapped up pretty fast when up for sale.
From what I understand they still use them in Australia.
The older VLF/TR machines were non-motion, so you could sweep the coil as slow as you wanted to fully analyze
the signal before digging. You can slow down and smell the roses....The smaller sniper coil works very well for prospecting.
I have the Eldorado myself, it's a great detector finds really small stuff. But, I prefer a non-motion machine with normal,
automatic and slow auto modes. So I naturally gravitate back to the oldies.
Now TR disc. mode, you need to keep the coil a constant height off the ground and tune it for that height. Or every height change will
result in a tone increase. Not good for rough uneven grounds. Switching to auto mode helps out as well as slow auto. In a nutshell
turns it into a super slow motion machine, no fast sweeping needed. And when you place the detector down to dig, the auto feature will
retune the threshold to where it was set to.
This tip is for you using the Eldo, it does not have a pinpoint button with a detuning feature, to narrow the signal. But, it can be done
by stopping the coil center over the target for a second, let the Eldo retune on it's own, Move the coil off the ctr just a tad, then move it
back over the target. You will find the target narrows after several passes to pinpoint it precisely. This method works well using the stock
coil when there are multiple targets that sound like one. This way of detuning takes about the same amount of time as detuning on
older machines using the toggle or push buttons.
It's amazing how an older designed detectors can still keep up with modern ones.
I will shortly revise my website that will include Garrett detectors from 1973 thru the 1980's.
