ID numbers problem/question???

[unearth]

I was at the beach today hunting, dry sand, manual, 30, seawater enabled, beach program and what do I see as a F/C number...0.0! What is that all about, 0.0? This didn't happen all the time, but enough to make me wonder what's going on. This has happened before and I can't figure why it's happening. It seemed to happen when I was having a hard time pinpointing a target. Anyone with an idea, please let me know. Thanks in advance.

I have never saw 0-0. But If I do I will dig it. I have gotten a few deep targets at the beach that just popped up on the screen with no tone until a couple of scoops of sand was removed. Someone said " When in doubt dig it out " especially on the beach. Interesting thread. HH

I am a regular beach hunter with the 3030 since they have come out. My first thought is manual 30 I rarely use mine above 24 dry sand and run mostly around 18 in the water wet sand. The only clue to too much is lack of targets! When it come to more less is always better!
This was my take for 5hrs yesterday both wet and dry hunting.

To understand you correctly, you're saying that my sensitivity may be set to high? Some targets may be missed if the sensitivity is to high? My understanding is that, run the sensitivity as high as you can, without the ctx becoming unstable, to get the ctx to it's optimum detecting condition. Is my understanding flawed?

Agreed! That is pushing it pretty hard.

So, if that is the case, how do you tell when you've hit optimum detecting capabilities of the ctx? Do you stay with auto sensitivity and let the machine decide?

The really only way to tell if your pushing any machine sensitivity too much is lack of targets. There isn't a gage to say hey too much! Too much sensitivity and the signal will bounce off the ground and many of the 24 frqs. won't penetrate.This is so true of multi freq. machines like Minelab's BBS FBS units. Rarely can I run a Excalibur over 12 o'clock without it cutting out. The same would be true of the 3030. Start off at a lower setting and gradually move up. Let your targets tell you if you penetrating the sand/dirt. Hunters forget that an 11 coil is huge and requires very careful tuning, it would be by accident you tune it correct when you walk on the beach. Then as you move the sand will change and you should be adjusting as you go. The threshold should not be haulting or changing as you swing. These machines are very powerful tools and too much will ruin your day. Next time you hunt find a deep target and change the setting and see what it does. If your running your gain at 30 you won't know if its deep as it sets all targets at the same response regardless of depth. I am a slow methodical hunter and want to know the depth by low response sound, note the gain doesn't determine the depth but how you hear the target at different depths. Now the manual says not to use the auto setting on the beach but I do with great success, its wild to see the swings in different sand in just a 50 foot area. Sometimes it reading a 15 with a recommended 18 and a few feet its a 20 with a recommended 22 and I went 10 feet. To test this just walk back and see it change again. What an eye opener! I will make a special note here that the Excalibur works so well at a slow controlled sweep speed, the 3030 likes it even slower. The Sovereign wiggle works so good to bring up deep targets, you haven't see nothing till you wiggle the 3030 over iron and trash and pull silver from 12 plus inches. You just stand there and giggle!

Wow, great info Buried craps NJ. Way over my head
But I will try lower sensitivity. Only been doing metal detecting a few months, started with ace 250 then got a ctx3030. Both nice machines but I like digging less trash with 3030. I do miss the light weight of the ace.Can you tell if the signal is bouncing off the ground by listing for to much nulling? I was very pleased that my ground lets me run very high sensitivity and now I'm not sure that's good. Please elaborate even more if you get time. Thanks Coondog.

Can you elaborate on that? I was under impression that most if not all VLF detectors put out the same strength signal regardless of the sensitivity setting and the sensitivity adjustment affects only the sensitivity to the incoming (reflected or induced) signal. Did I get it wrong or is CTX different than most VLF detectors?

Andrew while that may be true bottom line is conditions dictate sensitivity and other settings of any giving hunt. There isn't anything telling you your settings could be wrong. Far too many hunters are pushing the detectors to the max and the return is missing targets. More isn't always better.

I had that happen to me today. I was in Ground coin and had a target hit at 01/50 at 12" tried pinpointing and the TID went to 35/50 at 12" then I got a 0/0 at 10" and the sound nulled completely. I remembered reading this post on the 18th so I tried the 3 other modes, Ferrous Low Trash and High Trash.The 0/0 did not repeat until I switched back to Ground Coin. I was in auto+3. I did not dig as I was in the front yard of a high school. I run wide open as our modern clad up here is over 92% steel.

Ah, I think I know what you are getting at. With the sensitivity set to high, there will be so much return from the ground that returns from the deeper targets will not penetrate through the noise.
To me, the best indication of the sensitivity set too high is excessive falsing and (in fully open screen) constant chatter with every sweep.

When I started this thread I didn't include this statement. While I was at the beach, with the manual sensitivity at 30, I wasn't getting any chatter in the dry or wet sand. So, if the sensitivity is set to high and there is so much return signal, to block good signals, from the ground, then wouldn't the machine be very chattery? Or will the return signal, bouncing off the ground, not give off any sound or be chattery?

Not knowing where everyone hales from I am quite obvious. Here where I am at we have a very steep beach from crashing waves I rarely hear the threshold or nulling with a good pair of Blackwidows headphones on. The sea noise is too great to overcome anything other than a target. Add the wind and I sometimes have to walk sideways to the wind to hear targets! I am guessing I should add 22 years flying KC-135 A and E's didn't help either. My ears are shot for certain tones.
