Sov GT Depth ? or Broke machine?

Morning Folks
About a year ago the GT went back to be repaired and the coil was replaced. I never thought since the machine was there it was quite rite and finally got able to do some serious test this week. Would like some input on the outcome.
First when I got it back the speaker on the machine when you unplug the headphones "does nothing" nope no sound no mater what I do. Think that is wrong.
Second I buried 4 quarters at 4" and 6 " 8" 10 " at that time now that is about a y ear they have been buried in my yard (plain dry dirt no grass up here in the colo mountains) Ground is dry at this time about 6 inches down to moisture.
I tested the machine again this morning in various modes . Went to IM On and Sens on Max manual and Sens on Auto. Tried the same thing on All Metal mode. Then back to Im on and Im off with the sens both ways .
I can get "NO" signal on any of my coins. NONE l NADA ! I think the machine is better than tha if it is working right?????????
I Know the gophers got my quarters ? Nope dug them up just to make darn sure I was not going nutier than already am. There there.
Is this normal . I started the whole operation because all I was finding before I sent it in the last time which was the second time I sent in the thing . All I was finding was the 0 to 3 inch clad.
I dont feel like sending it back for another long wait but really would like to know is it me or has the ML went to lunch and not came back???
Thanks for any input

Grumpy,unless you are using a five inch coil your Sovereign should respond to the 8 and 10 inch deep quarters.With your description also including no speaker audio without the headphones I would send the GT in for repairs.You may want to try an air test.HH Ron
 
do you get a signal on the quarter after you dig it out. i got no signal on a nickle 1 pitched on the ground once. turns out that there was a large horseshoe in the ground under it. wave the coin over the coil, if you get no signal the speaker probably got disconnected.
 
Thanks Ron;
Im using a stock 10 " coil. The speaker problem dont bother me the headphones are required with my hearing anyway. but the depth of performance I thought was a bit Lacking?
Thanks
Grumpy
 
Something is wrong Grumpy. The sov loves quarters, I have gotten them at a foot and I would consider myself a novice with the gt. If mine lab did not fix it right the first time let them know. If they do not expedite your fix copy the forum. In the past they have been known for great customer service
 
The coil is a 10 inch factory coil; We air tested the machine to ch eck and fount 6 inch max? ????? Ant that kinda lame??? I would think it should air test at a foot or so?????
I would like to know what a normal Sov GT will do and of course we are in a high mineralized area but air test should still tell what to expect. There not to much smog in the air here in the rocies to effect :confused:
Thanks to all for all the help as always its great
Grumpy
 
Art;
Used the clad quater flat ; the one before the states with the eagle;
Used IM On and IM Off other knob in pinpoint dont think I tried all metal
Used sens on max and in auto very slight hum in threshold
Used the factory 10 coil
Used 180 meter reading of 180 when it picked up the quater was accurate.
Max I could get a good signal air testing was @ 6 inches.
Thanks for any help
Grumpy
 
OK so far...or maybe not........
Disc and notch all the way down.
Air test for ANY response no matter how low it drops. Don't just look for a 180 reading. Keep going until any more distance does not give you a response of any kind.
At max sensitivity you should get a quarter to give some kind of response at around 11-12 inches. it will sound like foil.

Air tests do this....target ID drops like a rock with distance. Ignore the ID and just listen for a response.

Do this with the coil off the ground. Test in IM on and freq 2 selected.

Art ;
Have DIsc off nothing disc out; I hunt that way
Same with notch I dont use it either;
Use Headphones to make sure of sounds and checking for sounds only just check the meter to make sure it is ok
Get good sound about 4 or 5 inches
Get good enough to check it out at 5 or 6 inches
Dont know you passed it by the coil at 6 to 7 inches ; no foil sound nada
Machine stays on Band 2 ; dont know why just never had a need to move it I guess.
I will repeat all this this afternoon and check things by your instructions to double check ;
Thanks for the help
Grumpy
 
Just in case.....some overlook this....
Max sensitivity is fully counterclockwise, but not clicked into auto.
If you had the sensitivity fully clockwise I would expect 6"

Make sure headphones on, volume max, threshold a faint hum.

HH
 
Ok Art;
I got the sens right and with me and my crud I have I could forget anything but that is right.
Never hurts to check me.
Did a few things and am getting better results. Droped the brain on the cement (really) about five foot is all.
New results. The external speaker works now. Very good actually .
Just got through with new test. Had wife oversee to make sure I did it right.
Put the machine in all the positions ; sens mx manual. IM On. Band 2 volume at just under max ; threshold audioable just enough to tell tone change.
Got plastic ruller for checking distance: (metal one not to good ) :)
Machine all set up like you said tone change ID drops fast after about 6 " I passed a quater past at 6 " and got good tone (AIR TEST)
Past the same at 7 inches still can tell it is a coin
Past at 7.5 losing some of the good sound
all the way out to 9 inches still get some hit to the quater laid flat but not real good as I would expect
Out to apx 10 then just run iron over it to get the threshold to change and the quater changes the threshold back to a high pitch.
Nothing past 10 or 11 inches except th change no foil sound or anything I could tell but seems the th change up around 10 would indicate the machine is working as it is supposed to???
One thing I did dif (wife rules) I went much slower with the quarter than I had. Fast works ok at 6 but you have to go reeeal slow at 9 and 10 inches??

Thanks
Grumpy
 
Sounds a little on the weak side but not as bad as some I have heard of.

I only have my own detectors to go by . If someone else can verify that this sounds a little weak, then you might want to send it in.

Just checked mine again just in case I was thinking about the wrong coil.
Was still picking up a quarter at 11".

HH
 
Art ;
One thing I noticed and was wondering if you think is right , normal or ? When sens is on auto or on manual max air testing I could not tell hardly any difference in distance ?????
Grumpy
 
with 2 of the GT's iv had would hit a dime at 12" air test and 15" in sand thats with a S12 coil.my Elite is about the same.but i did have a GT and S12 that 12" was max depth no matter what i did,so there is a diff in detectors for sure.my Excal ll with stock 10" coil about 12" is max on a dime in sand.and on all these detectors Gold was about 1/2 the depth!
 
You should normally see less depth in auto than manual max. Auto is looking at noise levels and trying to adjust sensitivity to a best level for smooth operation. This usually results in a sensitivity level a little lower than you could get away with in manual.
The transformer in front of my house is usually hideously noisy and drives auto sensitivity way down. Because you can't see or hear all the noise beating the detector, it makes results unpredictable. Different locations will have different results in auto.
There will also be some differences in manual between quiet and noisy places...the detector has to see enough target through the noise to pick it out.

I generally expect manual at minimum to do about 6".

Keep in mind that straight air tests are only good for reference under a fixed set of conditions....not counting noise. In the dirt things change a whole bunch and do not tend to give repeatable results over time.

I get different max "depths" on air tests with different coils. My 12.5" Detech is the hottest of the ones I have now and will get another inch or two over the others. In the dirt, it depends on time and place which is best.

HH
 
should be deeper in the ground than air, so doesn't sound too bad, maybe worth sending in in the off season just to check
