What settings should I use to get the absolute best depth.............
- Thread starter big-ears
- Start date
There are so many variables that what works best in my soil may not in yours.Your best bet is to plant some coins both silver and copper at depth up to 10" and then put it in manual sensitivity and crank every thing close to max except disc. which as you stated should be a bare minium in iron mask.Then proceed to test targets and tweek for best depth according to signal quality.If you are hunting where the trash is not to bad you can run the man. sens. way up till it gets to noisy for you and becomes unstable.However if you are at a trashy sight you may get better depth with sens backed off to near the auto plus 3 reading.You can even start your preliminary testing in the air and learn quite a bit about best depth adjustments.
One of the most important things to learn and remember is what good targets sound like at the very last inch of depth at any given sight and combination of settings.When you learn the softer less solid sounds you get at max depth it will help a lot as they are not near as solid and clear as a mid-depth signal.Also the ID numbers will change a lot at extreme depths but once you here and dig a few coins at max depth you start to get a feel for them.
If you have a old sight that is private and not a problem to dig several big deep holes it will be a great help on learning deep target responses as you can use a bigger shovel and dig a bunch of so called deep "iffy" targets and gain some very valuable knowledge.
I first learned this at such a sight and was amazed as I started digging those deep sometimes broken up signals.Silver will not loose it's solid quality tone and signal nearly as much as deeper green colored or corroded Indian Head pennies.I think some are having a hard time finding Indians with the E-Trac for that very reason.They will ID at Fer. 3-12 and con. 27-34 at my sights depending on depth,mineral and the amount they are oxidized.
I hope this will help some a little as it is hard to explain in detail but can be learned quite easy by experience once you know what to look and listen for.One more thing that will help is to find some good sounding and or IDed targets at moderate depth and then proceed to back your sensitivity way off and or raise your coil and learn how the signal tone and sound changes,Ray.

What Dan says is true. I have hit iffy targets running in auto+3, toggled over to manual sens and it improved the signal. HOWEVER, as Ray says, "if you are at a trashy site you may get better depth with sens backed off to near the auto plus 3 reading."
I have found auto+3 to be working very satisfactorily, and there are few sites that I am on that are clean enough to run high manual sens. (Just FYI, I ran high manual sens on my Explorer, so I'm not afraid of high sens).
But, at least for me there is another part to this equation which I think is that depth is not everything! Accurate ID (or good sounds from good targets) is more important than raw depth. Ideally you want depth and accurate ID. I feel most higher end machines with similar sized coils will get the same depth on a hunk-o-metal. The question is when you hear the signal, will you dig? If you have a big shovel and dig everything, this is not an issue, but if you're in a manicured park that dates back to the 1870s with a Lesche and a park maintenance person hovering, choosing which deep signals to dig is of great importance.
I spend too much time by myself.
