A good way to set the filter for your particular soil conditions: First find a good isolated mid-depth target, 4-6" with a solid repeatable tone and ID. It doesn't matter what it is as long as it's non-ferrous, a pulltab works great for this, or a mid-depth penny. Then lower the RX gain waaay down to like 1-3, down the lowest you can go and still barely get a signal on the target. Then start trying the different filters and you will soon find a filter or two that works much better than the others. It doesn't so much matter between band pass and high pass, but the kHz matters a lot. I usually find that 5 works the best in my soil which is mild overall but high in iron.

In fact, using this method of finding a good solid mid-depth target, lowering your sensitivity way down, and then making adjustments is a good method for testing many adjustments on the V3i, like recovery speed, adn AC/DC sens, S.A.T. etc. You can learn a lot about your V3i by experimenting on "fringe" targets...that are only "fringe" because you've turned the gain way to down to make them fringe. The added benefit is, of course, that on normal gain settings you know exactly what the target is and how deep, and that the target is in undisturbed soil.

" Then lower the RX gain waaay down to like 1-3, down the lowest you can go and still barely get a signal on the target."

Question. What do you set the DS and AM values when you change RX drastically low? If it's different than a factory prog setting, then how is this values calculated for this test? Nobody has explained about this when they say drop the RX way low. Hopefully I will learn the answer here.

It doesn't matter. Once you lower the RX gain, you can leave the DS and AM sens at the factory settings. Works for me. All you really need to do is simulate a weak target, and reducing RX gain accomplishes that.

I did what you said to do during lunch today. I used the Ground Filter of 5.0Hz after lowering the Gain. I tested this on a 5" deep quarter. After doing this, I went to the coin garden and hit my 9+ inch deep penny and dime EASILY! And in fact, I was able to lift the stock coil above the ground at least 3 inches and still hit them with a digable signal! Wow!

My only problem is getting silver-like hits off of bent square cut iron nails or getting silver-like hits near other square cut iron nails.

I have found more gold jewelry with my V3i than all the detectors I've owned,learned and used in the last 20 plus years.
Once you learn the sounds it produces you'll up your gold finds dramatically.

Hey badlandsbilly, do you mostly detect in 22kHz for the gold?

Your soil in mich. Shouldnt be too bad so try running 5 band filter, run your rx gain 10 to 13 and bump your disc up to 83 to 87 and your AM sens up to about 70 and see how that works. Go much hotter and you might get a lot of ground noise or interference with that big a coil. Go to the whites forum and read up on how to do a ground probe. This will help you determine your settings.

This is virtually exactly what I run with a U13, and in my test garden an 8 inch Merc, is without question an 7-8 dime, consistently!

I did as you said to do today but was using the 10" D2 coil today. I was able to run sense at 90 but ran rx gain around 10.
Two targets were about 8 inches deep, The token and silver cufflink. But the sounds and spectragraph looked horrible. I dug them out of curiosity
just to see what could be looking and hearing so bad. I guess I'll have to do this more often.

That's good to know.
I have a 9"+ buried penny and dime in the back yard. I can not only get my V3i to hit them well with the 10" D2 coil, I can even raise the coil about 3 inches
off the ground and still get a VDI on the coins. Not perfect but a digable VDI!

As you continue to learn all the functions of your V3i you will continue to be able to clean your spectragrah' right now it tinker with just the sensetivity and try the 5htz band pass. Winter will be on you soon enough to read. And i suggest read multiple times. I have a 3 ring binder of printed material and notes, it truly is a never ending process. However you will have a tool, not only capable of depth but the most accurate ID I've had. I feel I dig more trash with the Etrac, than the V

Big Treble or anyone who knows,
Once I do a Ground Probe, how do I know what settings to make for a near perfectly tuned detector?
