Tom Dankowski Tips For Low Mineral Ground

Recommended Posts

The Recovery Speed info was an eyebrow raiser for me. I pretty much run my detector exactly how he describes with great success except for the 2-3 Recovery Speed.  I hang out from 4-6 but never really gave much of a thought to trying anything lower.  It was interesting to see the EQ is tuned at RS 3 for ultimate performance if your soil will cooperate at that speed..

 I will be doing some testing with that and maybe pushing my sensitivity a bit more to see if I can eke out some additional performance..  Hard to imagine it getting much better then it already is..

Yup, that's the ticket. It is honestly almost a waste of time to get opinions on the internet when you have a detector in hand. Have an Equinox and want to know about Iron Bias? Go find some of your targets in your ground and run through the setting from end to end until you understand it. How it acts on others people's targets and in their ground is nothing more than an aside really. In particular there is a huge gulf in communications that exists between the high mineral folks and the low mineral folks. It's two totally different worlds and what works well in one world almost is sure to fail in the other world. The Florida crowd would be at a total loss in the Sierra Nevada greenstone belt.

This discussion of using lower recovery speed, 2-3 on the 800, is a bit mind-blowing, as I've never ventured below 5.  I seem to recall that in the early days of Equinox availability, it was pretty much gospel (on this forum and elsewhere) that if you weren't using 5 or above you were pretty much wasting the capabilities of the machine.  Anyway, on my next trip out I'll be lowering it to 3 and slowing down and see what happens!

I’m definitely guilty of not doing as much testing as I should have with both iron bias which I run at 0 all the time and Recovery Speed which I didn’t give the extreme ends of the range 1-3 and 7,8 any chance at all.

Hopefully I don’t make myself look too stupid here, but I think what surprised me the most about Tom D’s Recover Speed explanation that hit me between the eyes was that the settings don’t actually change the actual recovery speed of the detector at all.. just the audio which either gets clipped or elongated..  I knew the audio is different at each setting but maybe I was thinking the detector was actually working differently.

Now I know it’s more about understanding the audio at these different settings and probably the swing speeds that go with them.  

Sometimes you just think you know something until it gets explained to you differently and then it clicks.. Now I can revisit this Mode and look at it differently.. I would have never thought to try ultra low speed in a heavy target situation.

I really wanted to understand that thread but really most of it went right over my head. Between lots of references to other detectors I don't know and the jumbled writing style I just couldn't follow.

I tried Tom's settings yesterday and compared to Park 2 with the same settings Park 1 was much smoother and more intelligible.  So I have to agree with Tom on that one.  Picked up a few coins and a silver ring in a well hunted spot that were definite good signals, so there's that also.  Based on yesterdays results the Park 2 Recovery 4 settings I had settled on for most of my hunting might well be history.  Will know more after today.

Thank you for the reminder.  I remember years ago when the Fisher F75 first came out.  It was, a have to have detector and to start with I found a lot of very good targets in areas where I had already hunted extensively. 

What I'm about to say, don't take the wrong way but I started reading all of Tom's posts on how to get the max out of the F75.  How you needed to run with sensitivity maxed and discrimination at 0 and the next thing I knew I was trapped into thinking (my fault) I was missing out on finds because I wasn't using these settings.  I became extremely dissatisfied and finally sold the detector off.  Bought another one to try and the same issues the machine was just to noisy, sent it in for a check up and they replaced the coil but upon return still to much noise trying to run according to Tom's settings.  Many times the machine wouldn't quite down even with sensitivity settings of 50-60.  Went through several more F75's before realizing his setting were good for where he hunted but in no way acceptable for my medium to high mineralized, red clay of Virginia.  And then I had to take into consideration EMI, yet another story all together. 

It's nice to read about other hunters successes with their machine, using their settings but all thing are not equal from one location to another. 

I know and realize Tom has much more experience than I but there's more to successful hunting than just a particular setting/settings.

Took a long time to realize that.

      Dear Friends ....  Have purchased the Equinox 800 and Would like to know if anyone has had or used this coil and would like to share your thoughts on/of this coil. I realize that it has not been around all that long but perhaps some of Our Forum has had some hands on experiences with it? Any an all remarks would be appreciated.  Considering on purchasing! Thank you very much! Co

      My new T2 arrived this week so I decided I'd take it out for a test run today, I haven't bothered detecting football fields before, it never really crossed my mind to do so especially small town football fields that barely ever get used.  I think the last time I even saw people on this thing was about a year ago and they were riding a horse 🙂
      I guess back in time it was probably a popular place and my results today show this.  This is going to be more of a picture story as the pictures tell 1000 words! 
      I started using the T2 with Mars Tiger coil and within two minutes of arriving I had my first coin, then another, then another..... it was nuts, coins everywhere and very little junk, I was finding nice old coins, possibly one of my oldest in a while too

      Silver 🙂

      1938 British Penny

      The T2 was getting good depth, easily hitting on coins with good ID's, another silver!

      1948 Penny -  Now NZ currency, not British like the older Pennies, we used some British currency until 1967. 
      Prior to 1933 United Kingdom currency was the official legal tender of New Zealand, although Australian coins and notes were also generally accepted.
      The first New Zealand penny was minted in 1940. The penny ran until 1965, when New Zealand stopped minting pre-decimal coins in preparation for decimilisation in 1967.

      I have no idea what this thing is

      This is the football field I was detecting, under the goal posts and along the end of the field had a good collection of coins,  I guess from all the diving with the ball and coins in the players pockets, I don't know much about football, probably the only NZ male who has no clue about the game 🙂

      My oldest find of the day, a British 1912 One Penny

      It was quite deep down but the T2 banged on it real hard with a solid ID.  At this point I decided I'd go home and gear up better as this place obviously has a lot of good old coins.  I was only using my T2 with Carrot and Lesche digging tool which was hard work with all the coins being so deep.    I wanted a bigger coil to cover more ground but there was no way I was going to strap on the 15" Teknetics coil to continue using the T2 as it weighs a tonne.  I opted for the Equinox with it's 15" coil  and almost straight away after turning it on, another coin

      1950 NZ One Penny.  I left the bit of dirt on the coil up the top it came out of, I love when you get the impression of the coin in the soil.

      Another silver, 1934 Shilling

      This is the hole it came from, I always recheck my holes and I'm glad I did, another target in the hole, then another... this was crazy

      3 Silvers in the hole so far, 1934 Shilling, 1934 Shilling and a 1946 Sixpence, I was sure this was it but I did another check and off to the side of the hole, ANOTHER SILVER

      Another 1934 Shilling, 4 silvers in one hole, incredible!   Someone had a bad day.

      1964 Sixpence... the coins just kept coming, all old ones.  No longer are they made of silver in 1964...

      Nice and deep though
      My first modern coin, a $2

      But look how deep it was, it was deeper than a lot of far older coins.... weird!

      Another two in one hole, just one cent coins from back when NZ had one cent coins.

      Another coin leaving a cool impression of itself in the soil, just a one cent I think

      It sure a lot of ground to cover, I'll be at this place for weeks... plenty more coins to find I'm sure.  Time to head back to the car, with my coil to the soil.

      Another for the road 🙂 Double sided impression on the soil with this one.  I couldn't possibly put up a photo of every coin find as there were just too many, all in about 3 hours detecting.

      The good stuff

      The bad stuff... not a bad ratio, good stuff far outweighed bad stuff, unusual for me.... I'll be back there tomorrow.... and the next day.... and the next day 🙂

      On the advice of others on this forum, I called Minelab today to inquire about the play I've had in the shaft on my Equinox since day one. When I called back in 2018, they wanted me to send the whole detector in to get looked at. This time they said they would send the three pieces my way, and I just need to send the originals back to them. Has that been your experience for those in the same situation?

      As said I like both the Sport and the Nox face . The great thing about them as you hunt you can really look at the face of each and know what you have notched out . What makes the Nox even better over the Sport is you can notch out one number at a time .
       Oh I know the Nox has so many fine qualities over the Sport it will never have but like the Nox it has a pretty face .
       I don’t know why but a pretty face always tugs at my heart strings and a detector is no different.
