How much depth are you getting with the 6" coil?

[beachdude]

I have an iron nail filled trashy area that is under 5 feet of lake and it would be ideal for the 6" coil, but every time I use it I don't seem to get depths beyond 4" (as shown on the display). Most of the good targets in this area I have found with the standard coil at over 6 inches deep but it is not the ideal coil to use in this area because I am probably getting a lot of masking from all the iron. I am wondering if my small coil can even reach the good stuff....

I find it I crank up the sensitivity to high with either of my coils in this area I get too much falsing so I leave it on auto.

How much depth can I really expect to get (best case scenario) with the small CTX coil when set on auto sensitivity?

I myself have votten targets as deep as 7 inches so far.

 

[beachdude]

hmmm. Maybe I will give it another shot.

I haven't used mine a lot but when I have most of my target have been in the 4 to 5 inch range. I've had some targets read 6 or 7 inches deep but were not that deep when I dug them out. It does very well in high trash.

I hit a quarter at 8" with 2 nails in the hole. It will go deep enough. Crank up the VOLUME and listen for squeaks. The VDI numbers are off though by a couple.

Mike, just so that new users don't get confused, it's TID, not VDI.

 

[Detecting History]

fair enough. TID. What the heck is that?

I think target I.D

 

[Detecting History]

ah. I just know what those numbers mean in the ground

I suppose the real answer is "It depends" on soil condition, water, iron, trash, emf, wind blowing or not blowing, acne or no acne, sweaty palms, whatever! I use the 6" coil on really trashy demo lots, manual sens in the 24-27 range all the time, open screen, and I have dug dimes at 7-8 Inches and even today got a 49 rosie at about 7 inches. I found that if I run in auto +3, I 'think' I am not getting the depth needed, so I run in manual.

Last Saturday I used the stock big coil, not the 17", with sens at 30 and was getting a penny signal on a plastic gallon jug of coins at about 2 feet down in sand. It was reading 12" and on pin point it was showing 5-6".

I've gotten up to 8"

You cant put a hard # on deoth as way to many things effect it. Average 7-8 inches, sometimes 4. All depends.
