How high does the depth counter go

I don't have my CTX with me but I'm thinking 12 inches? And I was wondering if you get a target that is 14 inches will it say 12?
 
It has been awhile but pretty sure I saw mine hit 13.
 
I think it maxes out at 12.
I was playing around with an air test yesterday breaking in my replacement 11" coil over a pulltab.
It would give a tone at each inch increment I raised it, all the way to 12".
Once past about 10" the tones were getting weaker and VDI's were crap, but still had a blip of a hit up to an easy 14".
The displayed depth stayed at 12".
 
INSAYN did your stock 11" coil go bad?

I don't think it "went" bad, rather it was defective from the get go.
It never acted right compared to my 6" coil. The 6" is stable and has really good depth in Auto or Manual, in bad ground and under power lines.
The 11" freaked out in places that my 6" never would in Manual. Not sure what was causing it, but the screen would look like a firework show with numbers going all wacky all without ever swinging the coil. Switch to Auto and it would mostly clear up, but be single digit numbers. The 6" coil in the same area, same day would run smooth in Manual up to 26-27 and just be chirpy while sweeping any higher. In Auto it would be 18-20, and hit deep 6" targets.

The other odd things the stock coil did was miss on targets I knew was there. For example, it hit a Canadian dime at 8" just fine. I dug it and was putting it in my pouch.
A kid was watching me and wanted to hear what the detector sounded like, so I put the dime on the ground and pulled my audio plug out. Sweeped the coil over the coin at different inches above....NOTHING. No tones, no VDI's. Checked at different directions with no response. Stopped to swat a Skeeter on the back of my leg and then turned back to try seeing that damn dime. Now it works, loud and clear at all angles. ???

The final issue convinced me get an RMA and send it in.
My buddy and I were in our heavily hunted out park when he found a war nickel, and then I found a V nickel. He later found a Merc at 4" right where I had kneeled down to dig the V nickel. He was excited because his V3i was screaming silver at him, and before he cleared the dirt from the hole I wanted to check it as I just went over that area. Nada! Nothing!
Thought he was nutz and was going to be digging a nail, although I wasn't even detecting a nail. He moved a bit of soil and at the bottom of a 4" hole was the '42 Merc in great shape. I had him leave it there so I could sweep over it again while it was down there. Nope! Nada! Nothing! From any angle, any machine setting/mode etc. Damn thing was pissing me off. Stood there scratching my head with the coil on the ground, while he admired his Merc. I had him sweep it over the coil and hit. Nice and loud! What?
Had him put it back in the hole, and it detecting it just fine in the same exact spot it would not just minutes ago.

I am convinced there was something funky going on with that coil, and some moments it was fine and detect deep targets, then switch over and act like it was sleeping and not even detecting.

So far the new coil is acting completely different than the previous. More like my 6" coil's stability, so I'm hoping I won't miss any good targets that I go over.

Enough about my coil issues, lets get back to the original question here.
12" is about it for displayed depth.
 
At anything past12 inches the ctx would not sound off on a target anyway not on coins or coin size targets. I can't get deeper than 8 inches with mine.
 
Your CTX has a serious issue, or some sort of settings problem. What is your sensitivity at?
 
GKMan, it doesn't matter. That is all I can get out of a air test using a quarter. Reading air testing doesn't mean a thing I just assumed this was normal. I've recovered some 5-7" targets. But sometimes think I'm not getting the depth that others get?
 
There are WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY too many factors involved with arguing/comparing depth. Your best bet is to meet someone in YOUR area, with the SAME or SIMILAR detector, and compare depth that way. If you question it, send it in. People on these forms do not know YOUR exact issue or condition. Don't get me wrong, some of these people offer great advice, but with issues, it is all speculation.

Whoa dude! Absolutely it does matter. With an attitude like that you aren't going to find much help on this forum..
Again, either some part of your CTX has a problem, or possibly a sensitivity issue. If you care to fix your problem you will give us more details about your set up. Besides that if you really think your CTX has a problem then this should be a new thread.
 
As far as the original question about the depth gauge, I have never seen anything greater than 12 which is most likely the limit. In testing I have had objects way beyond 12 and don't recall seeing anything greater than that number.
 
Insayn, if you read the response correctly, he was saying it doesn't matter what sensitivity he trys, no matter what he only gets 3-4" in an air test. Not "it doesn't matter" like he doesn't care.
 
He minced words in his description of what he was experiencing. So, if that is what digs a lot has going on and it is regardless of sensitivity, and this is after a hard reset has been completed I would lean more towards it being a faulty unit.

Nolan, I wasn't persuing Sir Digs A Lot's issue. I think you mean GKman.

I apologies for my controversial question
Click to expand...

I don't think it's a controversial question at all myself. Some detectorist believe that all air test results are set in stone and detector performance is weighed by these results. The only air test I've done is when I first purchase a new, which isn't too often, I run a few items under the coil to see how they sound and how they come up on the VDI or TID. That's it. Minelab has stated that air test, especially with the CTX will not give an accurate reading because it depends on the FBS2 technology to read the ground conditions. Most all detectors are going to have different air test results than ground results. As far as depth indication on the CTX, I believe what I read was 12 inches max on the digital readout when when it comes to target depth. And, any way you think you add it upthe CTX can pull some deep stuff to the surface. Anyway. That's my2cents.

Thanks and HH
 
My 6 inch coil seems to have been out performing my 11 inch coil.... :nerd: Way less EMI involved when I am using my 6 inch coil too. The 6 incher seems to hit 7-8 inches down on penny sized objects and the 11 incher hits like 7 inches max on penny sized objects. Sometimes I feel as if I should be getting better depth too, but due to me trying every combination and experiment I have seen on this forum, the depth does not improve in this area. I was having similar issues with my AT Pro before switching the CTX 3030. It seems the problem either lies within the soil here or within the detectors I have used. For these reasons it is good to have someone with another machine to meet up with you and compare results. So far there is not many people close by my area and the ones who are nearby are scared of the competition! :poke: I can't win for losing.
