so you are hunting in pin point mode with the pin point hit and locked on ?

amberjack,
I'll share my experience/technique, and we'll see if sube can chime in to add anything to it...
Short answer to your question: yes.
Long answer: Here's what you need to do:
Mikes' Secret Sauce:
1. Make sure you've turned on pinpoint trace and pinpoint lock.
2. Find an area where the audio (in normal hunting mode) becomes 'unintelligent' and overwhelming.
3. Switch into the all-metal pinpoint mode with the pinpoint trigger.
Now here's a little tricky part...the CTX 'ground grabs' when you click the pinpoint button.
That means you just switched to a non-ground-tracking mode, and that affects the threshold tone...and ultimately depth.
So either:
a. If you ground minerals aren't TOO bad...just hold the coil over some clean ground...either directly on the ground or a couple inches above it...BEFORE you switch to pinpoint mode.
This will ensure that you can still clearly hear the threshold tone. (More about that later...)
b. If your ground minerals are bad...I've found the easiest way to deal with it is to hunt with ground balance enabled (and carefully balanced)...this will prevent your threshold from disappearing in pinpoint trace.
Again, this wil ensure you can still clearly hear the all-metal/pinpoint threshold tone...but spend a little time balancing to get it as 'right' as you can.
You should be able to lock the pinpoint with either your coil up in the air...or on the ground...and hear no threshold change when you raise and/or lower it.
4. SLOW DOWN. You're now in a non-motion (visually) discriminating mode. Move the coil SLOWLY and in small amounts, while carefully listening to the 'quality' of the signal.
If you look at the screen, it can look like a radar screen...filled with multiple targets being painted in. (When the screen gets too full, just quickly click pinpoint off, then right back on to clear the screen.)
5. When you hear some promising audio (small/tight signal among the rest), watch the screen and cursor as it paints in whats under the coil.
The display will (usually) continue to display the changing conductivity numbers and depth...(this is so cool)
Only move the coil back and forth enough to see where the cursor wants to jump/paint.
It can sometimes help if you mentally visualize you're actually painting the screen with your coil as a brush. (yes...that slowly)
6. When you think you've got a good one, make sure you're over the 'goodie', and dig.
The benefits of this include being able to tell a lot more from the quality of the sounds in pinpoint...which gives you indication of all the targets...no matter how close.
(Of course you lose the different tones and audio disc, but it's a true non-motion (visually) discriminating detector in pinpoint.)
Extra bonus tips:
When you're hunting like this in pinpoint mode, listen VERY carefully to the threshold tone.
It can indicate a very deep coin (at the maximum 'fringe' range) by an extremely subtle threshold tone shift. If you're not listening for it, you won't notice it.
You'll want to practice lifting the coil over a buried good target to hear that extremely subtle shift.
Once you've heard it, you'll know what to listen for...to get the deep ones.
Since you're operating in a non-motion mode, you can increase sensitivity a little more without falsing...non-motion doesn't 'false' like motion mode.
Have fun,
mike
