single frequency deep?

[josyaguilar]

I have a colonial place, where a lot of silver coind came out, from the 1700s, I think there are still pieces but they are more deep, the equinox always use it in multi frequency. it is true if I put it in 5 or 10 khz I will have better depth. this place is very mineralized and I tried once to put it in frequency 10 khz I get false marks .... for the experts people, what I am doing wrong .... thanks

You can lower your recovery speed I always hunt in multi but use no discrimination and run my sensitivity as high as I can I’ve been using field 2 also I like that setting in my area ..

Ideally, single freq is deeper but in mineralized soil it may not be. Try each freq and also reduce your sensitivity.
High sensitivity (in single or multi) will cause the detector respond to mineralization (falsing). By reducing the sensitivity it will respond to the "good" objects hopefully ignoring the mineralization.
If the soil is really bad there’s not much you can do but dig everything, or use a pulse machine and dig everything.
Increasing the recovery speed (if there is a lot of falsing the detector "speed" needs to be increase to see things in between) and slowing down may also help pick out a good object.

I like 50 tone, may drive people crazy, but I listen for a tone that "pops" up (above the clutter/falsing) and then see if it can be somewhat repeated and isolated.

The single freqs have all been tested against the multi-modes and found to be failures. Multi out-performs singles over 90% of the time, ESPECIALLY if you have bad ground. There are only a few situations where a single freq can be the best choice, typically when dealing with EMI.

If you have the 800 you can hunt in Gold 1 or Gold 2 multi. I know it is just one tone audio but if you are looking for silver just dig the upper 20s to mid 30s signals and lower your recovery speed if you can according to trash levels.
Also, manually ground balance. Gold 1 and 2 with manual ground balance theoretically uses the least amount of filtering and processing of the return signal and should be able to detect deeper than the other modes.

In theory you should be able to go deeper on high conductor coins in single freq at 5khz because when running multi the lowest freq used is 7khz, but in reality multi always wins.
1700's silver is going to be high conductor milled coins so you could do as Jeff says and run prospecting mode and only dig the high numbers, where i hunt some of my silver coinage comes in as low as 6, so your lucky you have this option.

One of the very first things I tested with my Nox was general depth ability, using 5khz versus Multi, and I personally found that in my dedicated coin garden, there was so little difference running 5khz, Multi frequency with all of it's glory, is still the sanest and easiest mode to use. My Whites V3i had 3-frequencies, 5 being the lowest, ant 5khz on the V3i really did get measurably deeper than 3-freqs. I saved myself time and distraction by just realizing that Multi "had it all", so I've not gone to 5khz on the Equinox in many, many months.

I suppose that 5 kilohertz could perform very well in very sweet soil conditions. I don't call my soil sweet, yet it is not high minerals by description either. I say, "Just stick with Multi" and try and resist getting into a lot of tweaking. Jm2c
