SATisfied ? (For Eric)

A

Anonymous

Guest
Eric,
I'm not completely satisfied with my understanding off the SAT control function.
I currently set it at the MIN position as this gives me the strongest/deepest target response.
With REJECT set at about 16uS and the SAT speed at MIN, the unit is nice and quiet in the water up to a few feet deep.
I understand the SAT relates to the retune speed, which is necessary in conductive/mineralised ground, but may also aid in target identification.
With a slow sweep speed in the water (and on the ground), is it still preferable to increase the SAT speed before making any REJECT increases? I understand that an increased SAT setting can help overcome audio fluctuations generated by waves and rushing salt water.
Hope this makes sense to you. A quick overview of the Goldquest's SAT speed control would be appreciated. Apologies if this has been covered by you before.
All the best for the New Year
Tony.
 
Not Eric, maybe this will help ???
Run with the SAT at the lowest setting you can, and still maintain stability, regardless of the delay/reject setting you choose.
Slower is deeper, and easier to pin point with also.
Best results when running slow SAT speed is to run slow sweep speed. Increasing the SAT speed "May" allow you to operate with a faster sweep speed.

This is an interesting question. Whilst agreeing with Mr.Bill re sweep speed and SAT I find pinpointing far better with increased SAT speed. Both Deepstar and Goldquest suggest a mid (12 o'clock point) for an inital setting. I tend towards the one o'clock position as I feel I get better pinpointing and its easier to tell iron by the double note in one direction method.
In air minimum seems the deeper (compared to 12 o'clock) and maximum does sacrifice depth but the loss at the mid/mid plus seems little especially if the threshold is also increased a tad. If your trying to locate a small ring in water would it not be best to improve the pinpointing if possible?
My comments are based on wet sand, not being right in the water so this might alter things.
With the order of adjustment I run through the adjustments finishing up with the SAT (which doesn't get moved much anyway). I then return to the reject knob and see if I can tweak it down a fraction more.
Lets hope some more people can come in with their views/settings.

Tony, I have read your post and the returns to always pick up new information, learn something new everyday...
Personally I use a very large scoop when dry sand or wet sand hunting and don't care if the loop is a few inches off pinpointing...I am going to take a full scoop worth of material and if the target is not there I will take another. If I was in someone's well manicured yard I would insist on better pinpointing and be using a pin pointer to really get close...but I have no problems with the Goldquest SS pinpointing on the slowest SAT and runing at the lowest number uS I can for most sensitivity and depth combo for gold...Our real advantages is being about to detect in Level 2 and 3 substrate below VLF's....I guess I do not want personally give up any of that advantage...
This is my personal opinion and you ask for others to respond..
 
Frank/Brian/Mr.Bill,
Thanks for the feedback. I'll certainly be playing around with the SAT to see what works for me the best.
I suspect that SAT at MIN and REJECT at about 15uS will be my mainstay setting as this has the detector running almost silent on all wet and dry sand and in water to about a metre deep. It's interesting to hear what other people have to say on the matter and it surely is a matter of personal preference.
Frank, I think your settings are very close to how I set my Goldquest up.......I'm still astounded at how deep I have to dig though !
I got a nice rolled up tube of toothpaste the other day (the old style of metal tube) at no less than 2 feet. I don't think it had seen the light of day for some years.

I used Calrad earphones as I did not believe there was that much difference in el-cheapo's and higher quality earphones...Wrong! I got an inch to inch and a half better air test on a US. Nickle with the Grey Ghost. Now on top of that I was setting them up wrong, I was setting the threshold and then the earphones level...Due to a post below I started turning up the earphones all the way and then setting the threshold...got more depth.
I find the sweep speed much faster than the other pi's I have owned, White's PI, CS7, HH PI. I can move along a a fairly fast clip and still get a half bleep of the audio...go back and home in on the target...even the very small, deep targets give up their presents with the Goldquest SS at a faily fast sweep speed normal for a PI machine, I can't really qualify it as a very slow sweep machine...
I post earlier with photo how to stabilize the coil wire for water use at 10uS.
I find the Audio is very descriptive, noy as descriptive as the old Tesoro detectors before microprocessors but I can generally be a better 'guesser' with the Goldquest... Soon as your ear develops its fine tuning on the audio, a penny is generally clear, silver is less a hit than iron and gold has a 'very soft' hit but solid hit on both ends of the sweep, the pennies will be a brash hit, loud and clear...
Just because it double beeps on most longated iron...I found a gold "getto" medallion that double beeped...it is 3" long... I almost did not dig it thinking it was iron but it was a soft double beep..Frank
