CTX 3030 is it defective or do I need more training.

Thanks Jersey! Down in SC. funny enough I went to Myrtle Beach (about an hour from here) seen someone with a CTX 3030 unloading it from 74th Ave North. Got to talking to him, turned out he was a book author 'Gold Beneath The Waves' he checked my settings and said my disc pattern looked very close to his and the settings were spot on. His theory was that I need to be wearing my headphones, which to be honest I really don't do, It's been so hot lately and those Koss headphones make for quite a sweat. They guy seemed very fluent with the 3030, actually I watched him go over an area I had covered the night before and he found a gold tooth I guess I need to find a decent pair of headphones that don't sweat me to death. My best 3030 find so far was a 1916 merc dime at an old school yard, and I could see a blip of 12:47 on the screen but absolutely no tones being emitted, just decided I mine as well see what was making my machine show what I assumed was a quarter at 10 inches show something without tone. Dug, dug and dug and found a near mint dime.

The CTX3030 Instruction manual (p41) notes that in Ferrous-Coin setting there may not always be audio for targets on the screen.

LawerencetheMDer. I had no idea. I have target separation set to Ferrous-Coin. Is there a different Target-Separation I should try? Good eye man!

The only thing I would love to learn or get a better example of how to use is sizing.

I run into the concessional crushed can that gives excellent tones. From what the book says you can use sizing to sort of eliminate the need for digging this kind of junk but didn't give a clear idea of what to look for on the screen (never used sizing yet personally)

Is there a simple way to explain how to use this to determine if I am digging a quarter vs a crushed can that does not show overload. Can't seem to find much on Youtube, think once I learn it I'll post a video up to help others figure this one out.

sitedude,
Sorry, I didn't see this question until just now...

Yes, it's actually a very simple technique...
It's actually part of the old school mindset of listening to the sound, size, shape of a targets audio before even letting your eyes focus on any screen.
HOWEVER...it requires a detector with a fixed all-metal pinpoint threshold...IE no auto tune threshold...(thus the reason the sizing option doesn't auto adjust threshold)

Here's a link to one of the previous posts I made explaining it's operation in detail...read carefully about halfway through for the sizing 'specifics'...where the line starts "And one last thing..."

You can actually do the same thing with DD coils using a 'wiggle' method front-to-back (as opposed to side-to-side)...same rules apply...
Find where the sound starts at the leading edge, and goes quite on the trailing edge...the difference is the size.
(It might help better for really shallow, multiple blip targets.)

Good Luck, and hh,

mike

And here I have been training myself to be a tone hunter :/... wonder how many good targets I have passed over by not watching the screen??
