Using Tarsacci’s Salinity Balance To Disc Out Small Foil & Find Small Gold

Recommended Posts

This is a awesome feature especially for the park and beach hunter, check it out!

Thanks!

I tried this on the CTX open screen and it worked. I used 4 pieces of aluminum foil a little bigger than 1 inch  and stacked the on top of the nickel.  I didn’t test to see if it will hit on real small gold.  It even worked  on the ATX when I bumped up the discrimination to max.  Loss sensitivity to tiny gold though.

The purpose of the test was to show the Tarsacci could show the difference between 2 targets at the same VDI range, (foil/gold), which it does. The nickel is obviously a higher conductor.

Can you appropriately balance for salinity for a wet salt beach AND adequately cancel small aluminum simultaneously?

Chase, in my opinion the answer would be NO. Some small foil will be eliminated but there is an endless supply of various sizes and shapes of aluminum trash at a beach. I have noticed that 18kHz "seems" to be a better frequency for hunting in the small aluminum but if your beaches are anything like mine, you will find there is still aluminum to dig....especially in the dry. 

I haven't tried it yet but would like to see if you take one of those small pieces of flattened foil and just bend it up a bit (not in a ball)....I'll bet it doesn't get eliminated as easy.

I live in Michigan and cannot answer that question. However checkout my latest video where I have tuned the Salinity to disc out both coke and aluminum foil at the same time while still excepting a extremely small hammered coin.

To answer that Chase......ill say it depends on whats and acceptable loss gold wise.  The machine wasnt designed to hit micro gold..... but does well on fairly small gold and excellent on gold rings.   Id have to agree with Cliff.....if your salt balance is correct.... raising it much like over GBing for raw gold hunting you are going to loose some gold that just makes sense.  Ive had to run a high salt balance when playing around with 12khz in the salt water..... that balance being around 44.   It may well balance out very small foil but it does seem to affect the target response.   I tested a good many found targets using both 9 and 12khz.   Over a deep pull tab you get a pretty clear obvious target tone.  When using 12khz with the high SB.....it sounds weaker and shorter something you might miss especially a near target.   Keep in mind im in AM running a very hot machine.   But ..... fresh water just like park hunting is a different beast.   Not enough dissolving of targets or water movement to move a lot of that small foil out of the water.  I assume Aaron is hunting in disc..... and his disc is -30 which keeps targets like iron from wrapping around to high digits in the 28 range.   Hes looking for gold rings and silver to include coins..... and thats a lot of trash......... thus there is an acceptable loss of some targets that may not have a lot of value.

The salinity control is a filter. Increasing it helps reduce or eliminate some salt or ground signals. It can also act to reduce or eliminate some false signals from ferrous targets. It can also reduce or eliminate some low conductor signals. Lead, aluminum, gold. Eliminating a lot of aluminum signals may be an acceptable trade for the possibility of some lost gold items. It is a trade off based on your experience and basically a little bit of a gamble. It’s really not possible to tune out gold of large size with the salinity control, just more like what people would call micro jewelry. Losing some micro jewelry not to dig pounds of aluminum might be acceptable trade, with size you will still be getting the rings and other desirable and weightier objects.

You could certainly get a good salinity balance for the beach while eliminating some aluminum. You really don’t get a choice. Eliminating the salt signal will take some aluminum with it, along with some gold. The gold/aluminum/salt range overlap, and affecting one will affect the others. What you can not do is tune out the salt entirely without affecting gold or aluminum in any way.

Is this what you ment to say?   As a filter.....anything near that small gold/salt level can be filtered out.   Me and Demitar spoke about small.... which some call micro gold that may not be picked up by the MDT.   He said it wasnt designed for micro gold hunting because speaking to hunters that wasnt what they wanted.  However, i can tell you air testing a lot of tiny gold there was only a couple items the MDT didnt get the Nox did......tiny tiny cross and a small hollow earring ..... but neither did the Xcal or CTX.  So .....like any machine we are working with acceptable loss.   But i believe the depth of this machine .... in the water surely makes up for that loss.

No, and thanks for the catch. What I meant to say is “What you can not do is tune out the salt entirely without affecting gold or aluminum in any way.”

The salinity control directly affects some gold (and aluminum, lead, etc.) items, either reducing or eliminating the signal from them. Not all gold, just the weakest signals.

      The MDT 8000 has an IP68 rating - up to 1.5 meters for up to 30 minutes. I’d call that more a wading detector than a mask & snorkel detector. On the other hand, I’d bet the MDT is at least as waterproof as an Equinox, if not more so.  I don’t think any of these so-called 10 foot detectors have a genuine waterproof rating exceeding IP68, simply based on the coil and headphone connectors being employed
      The question being, how deep for how long? Who, if anyone, has had the MDT submerged for more than a few hours? I’d assume that simply wading using the supplied headphones, with controls submerged nor more than a foot or two, would be good almost indefinitely? Though technically that’s not what the rating says. Up to 1.5 meters for up to 30 minutes.
      Anyone doing fully submersible? I just missed on a used set of Tony Eisenhower phones for the MDT, so I know that they at least are being made for the MDT. Is anyone else making underwater phones for the unit? I’ve got a set of Minelab yellow Koss I’ve considered converting, but need to prove I’d actually be sticking my head in the water more than I’m doing now before I’d go that route.
      The machine appears tight enough. The only thing I’d wish for off hand is that Dimitar double the number of threads on the battery cap. They seem sufficient, but just barely, and a few more turns would add some psychological safety at least.

      Tomorrow, 30th July...........
      im using the Tarsacci MDT on its first Roman site tomorrow,, 
      The field has only the headland cut,, (wholecrop silage),, but I can't wait to experiment with the Tarsacci, I will only have a few hours to spare here but really looking forward to this opportunity!
      ive been detecting this site since the early nineties,, (Fisher 1265X)  was the first detector I ever used here....(loved that machine),, and numerous other detectors since!
      Site has been detected heavily throughout, not just by me , but numerous of other people, so,,, should be an excellent place to see what the Tarsacci can unearth,,,, .. For the record, I detected this site last year and only found about  half a dozen coins,,, in a whole days hunt,, so it will be a great test!
      Hopefully some photos of Finds to follow, and a brief summary of how it went!
      regards
      Dave. H
