"Deep" Setting Question

[jimmyk]

My question as a newbie is why wouldn't you want the "Deep" setting "On" all the time? When wouldn't you want to enhance the signal on a deep coin? What's the downside of having it on all the time?

Thanks,

If the only targets in the area are deep, and things you want to dig, then Deep ON should work well. However, Deep ON requires additional signal processing in the CTX 3030, which slows down both the audio and visual response of the target. HH Randy

What's considered deep? In my area 4-8" is where I find most of my 1800 coins. I've been using deep on all the time, would turning it off benefit me? Thanks

If you've been having success with Deep ON and not noticed any "delay", I'd keep hunting that way. But it would be interesting for you do some experimenting and let us know what you observe.......next time you are detecting with Deep ON, before you dig the targets, switch to Deep OFF and see if you can tell any difference. Did the audio or visual display seem "quicker"? Did you notice any difference in the audio response from the targets? I look forward to reading what you think. JMHO HH Randy

I've noticed that if i'm in a super trashy area that deep on can slightly alter the speed of the machine when two or more targets being detected simultaneously. I believe it's a sort of "proximity" effect. The machine is trying to amplify a deeper signal while trying to reject or process another signal. if it's a fairly trash free site I prefer to leave it on. in heavy trash I leave it off with fast ON and then clear the spot as best I can, then I switch to deep on, fast off. Options, options options... It's just site dependent. I love them options though!

You might try raising the gain just a little. This will maintain the same processor speed along with the TID response while enhancing the deeper targets. If I go to deep on I drop my gain down to around 20 which works very well at the beach. High gain along with deep on seems counter productive for me in my ground. You may want to try like digger reccommended on some deeper targets in your area. HH

From everything I have read from Andy's Etrac/Explorer book and understood from trying it DEEP ON just enhances the target ID better of really deep targets so it's not jumpy and locks in better. Digger may know something I don't but haven't noticed the IDing/processing being slower from my experience though.

It's the VOLUME GAIN being turned up that makes the deep targets sound loud or louder depending on where you set it at so you won't miss them.

Also using SOUNDS LONG instead of NORMAL in a trashy area makes the clad and silver not be missed amongst all the trash and also if it's deep and a very small or very short signal it can make it so you don't miss it while sweeping the coil.

I saw this in a video from a guy from down under in the Etrac forum and so I tried it with my Etrac with the small 6x8 SEF coil I just happened to have on it at that time and I pulled a mercury dime out of trash and fairly deep, it was a good situation to try LONG sounds out in and it payed off. The signal was so so small and short it was just a quick chirp then I used LONG sounds and it was almost a normal signal response. I almost missed it.
