    Tarsacci Punches Hot Brick To Small Low Conductors

    in Tarsacci Metal Detectors

    Posted

    Chuck, I didn’t notice till after I did the videos I forgot to scan both gold coins. Regarding the before and after numbers, ,hmmm good question. If you saw my latest VDI US Coin video, I noted the $1 gold is 6, same as the clad nickel, and the $5 gold is 12. However I had to go back down and re-test both coins under the Keith’s hot brick for those numbers which varies. Whenever your trying to detect through heavy minerals your generally not concerned w VDI so much as “sound” and hot ground is always going to mess up the VDI numbers. So that being said the $1 gold coin jumps around but averages in the lows 20’s under the hot brick and the $5 gold coin averages in the single digits around 8 under the hot brick.

    Thanks,

    Chuck,

    There are no presets on the TARSACCI, however its not difficult to set up. I provide free training to all my customers if that’s a issue w you. Regarding  O-rings, no we do not carry them, however if I have extras I provide them to my customers. All TARSACCI dealers must honor the same policy regarding price and shipping. 
    Not sure how you tried to reach me however the best way is at: https://forums.tarsaccisales.com

    Glad to see you’ve received the 12” already Bill, didn’t I tell you you’d be impressed?

    Yes as I stated on my review videos, the coil is a BEAST, built for WAR and light too! Looks like the final production version is even better than the prototype, as mine didn’t have the over-filled epoxy resin. We do realize that there are still many who desire a cover for the 12” and we’re working on that too, as well as a few other things as well! 😉

    Nuff’ said!

    Steve what were your other settings if you remember? and were you using tracking ground balance? On thing I've learned about the Tarsacci is it's usually better to have it run stable than push it. At the point the machine becomes bubbly (hard to explain) it's time to back off either the Threshold or sensitivity. I personally like to decrease sensitivity down first because reducing threshold takes away from the target (Ability to hear deep targets). Yes black sand seems to reduce the transmission voltage as every time I've used it On vs OFF when comparing signals from targets, On always sounds worse. Another thing is I always salt balance even if it doesn't make sense for the area you are using it. Salt balance coupled with ground balance can be used to manipulate the Tarsacci to do some cool stuff. A discussion for some other time.

    But to answer your question no I have not had my Tarsacci audio completely shut down. I have had it blank out momentarily but I always thought that was my wireless headphones losing connection and maybe it was. 

    Abensen, 

    One of the reasons your Tarsacci is cutting out is due lack of pressure via the battery cap spring to the battery. To resolve this issue, simply remove the spring and metal backing disc and put a #6 washer behind the disc and refasten. This should resolve your “blanking” issues. If not check your battery connector strip. Take some steel wool and polish off any corrosion ect that may have formed. For more information check out my Tarsacci maintenance video......

    Silent Masking / Overload With Tarsacci MDT 8000

    Many of you will never encounter this. As far as i know, there is no overload indication with the Tarsacci. I have observed that with intense magnetite black sands you need to use caution about running the sensitivity too high, especially with Black Sand off, as I tend to run. I assume that cuts back on the transmit voltage to help prevent what I am going to describe.

    If you bury a nickel in a true black sand beach (looking at you kiwis) or my hot beach up at Tahoe where I did this test, you can  get the machine tuned up for conditions. However, if you get it cranked up too high, all the sudden you will lose the nickel. It just goes away as the machine hits overload, but so far as I know the machine has no way to tell you this happened. It seems to be working fine.

    Where this could bite you is tuning up on bad but not extreme ground, and then detecting your way into some intense black sand. You may go into overload without knowing it. This is not a freak out thing for most people to even worry about, but something I wanted to bring up.

    First, I do not read everything ever posted about the MDT. Has anyone else observed this? Is there an overload indicator I am missing? If not, maybe something for Dimitar to add later. Its a common feature on gold prospecting machines, like the White's GMT for a good example.

    "The GMT's circuitry broke a lot of new ground. It uses a reactive impedance transformation network to boost transmitter voltage for higher sensitivity. It uses an active transmitter regulator to keep transmitter voltage constant even when the search coil is moved over black sand that would blow an unregulated machine off the air." What this means is many detectors can actually go completely non-functional when operated over extremely mineralized ground and the operator will not even be aware of it. The GMT is very resistant to this occurring, but if it does the detector will give a loud audio "squawk" and the meter will read "BAD GROUND REDUCE GAIN".

    The GMT literally tells you your gain is set too high for the ground condition. Set the control lower until this message goes away for optimum performance. If I've not overlooked it, this would be a good addition for people on the worst beaches.

    Steve, I cannot comment on the black sand as I do not have any around here. However, if the Tarsacci does overload you will see a big OVL on the screen, and your audio will cut out. Nice write up.

    Couple Excalibur Gold 1916 & 1929 Class Rings

    First out for the year, found a spot that has cuts that are over my head. I know how they got there but best I hold on that for now. One thing for sure targets are every where, on the top shelf, down the slope, and in the bottom. Just have to wait for a better tide so I can hunt the whole bottom and not worry about sliding down the slope. Most targets are shallow. First gold was maybe 12 inch's? Going to be interesting to see how long this spots stays intact-ed. I knew something was up and one reason I took the Excalibur for I had no clue on what I would be walking into. I am debating on taking the 8 inch on the "AQ" next trip. Seems to be no trash at all....

    Three hour hunt, 1916 Class Ring and 1929 Class ring. 4 Silvers, which are eaten bad by the brackish waters of the Chesapeake Bay. Water is just dipping into the high 30's, full hunt I was toasty but Need to make some adjustments to my gloves, left glove is like wearing a sock.. No mobility.

    Great Article Written Especially For Begining Tarsacci Users

    in Tarsacci Metal Detectors

    Posted

    Here is a great article written by Teresa aka (Coilpower) on the Tarsacci Forum I thought I’d share.... 

    Tarsacci MDT 8000 Precis and Methodology for new users. 



    Having used the Tarsacci MDT8000 for relic, mud, water, beach and black iron sands since the beginning of 2019, this article is aimed at new users and as an optional refresher for others including myself. 

    A detector which gives PI depths but with target indication along with no sub menus....a weight of only 1.63kg, quality craftsmanship, superb ergonomics and carbon fibre components along with all the computations already dealt with “under the hood” within the unit itself, leaving the user free to only “fine tune” to the site being detected, is indeed “revolutionary technology.” 

    It is those last two words that in the beginning led to the presumption this detector was for the more experienced users and primarily beach hunting. NOT SO. It was later found by users to be a multi functional, multi talented detector easily learnt. So..... all that is needed is the correct mindset, a little time becoming familiar with it and of course experiment like you would any detector. 

    Several internet savvy people have taken great time and effort creating You Tube clips showing the attributes of the Tarsacci. For those with limited internet, I hope you may find the following exercises of some use thereby gaining enough confidence and eliminating frustration before heading out hunting with your settings....and.... READ THE MANUAL!!!! NB: Not written in the manual is which way to insert the EBL battery.....Insert it PLUS FIRST, otherwise it wont turn on....so don’t panic if you put it in wrong, no harm done. 

    Legend: TrH on unit but written here= TH = threshold, Dsc = DISC = discrimination, Sens written SENS =sensitivity, Gb = GB= ground balance. BlkS=BLKS=black sand, St=SALT= salt or salinity, Track=tracking, Fc=FREQ=frequency. PP= pinpointer. AM=a true all metal mode showing ferrous or non ferrous target, DISC = discrimination, MIX = mixed mode.....audio sounds are AM then DISC heard in that order. 

    Note the following “air” exercise is absolutely NO indication of the depths that can be achieved as the Tarsacci uses the earths matrix, also “test gardens” do not give quite the same results as “cold” hunting. 

    1. Collect a variety of tear tabs, bottle tops, coins, rings, etc....trash and treasure and keep these permanently in a plastic container for future use. 

    2. After the obvious basics of turning on the unit and becoming familiar with the buttons, note how the black outlined box has a much thicker black outline when engaged. It is then the user can change it. 

    3. BLKS and TRACK are the only two boxes that will be entirely filled with black when engaged. 

    4. Place each piece of trash/treasure on the lawn or concrete (without steel in it) in a large circle.

    5. Find a spot and using PP make sure there are no targets heard under the coil. 

    6. GB the unit, then SALT balance. When BOTH of these are in correct balance there should be NO NOISES heard. The unit is SILENT!! 

    7. Generally a good quick middle of the road setting is GB of 560 and SALT 27 may suffice. If not, adjust SALT up or down. With experience gained I cannot stress enough to GB and SALT balance correctly for SILENCE from the unit to the point you actually take a swing over your spade/scoop to make sure its working! Chatter, even slight, will distort signal processing by the unit to identify your target in a clean, clear, precise manner possibly tricking you to ghost targets not to mention a cacophony of sounds through your headphones. 

    8. For this exercise adjust SENS to 4, TH to 0, DISC to 0, BLKS off, TRACK off, FREQ to 18 and swing over your circle once with different settings from minimum to maximum in each. 

    9. Go over your circle of targets firstly in AM, then DISC then MIX. Get used to changing this MODE button without looking. You will find a personal preference of MODE and in the field no doubt will use all or one of them. 

    10. Again doing the circle, change DISC to plus 30, then minus 30. Note the audio feedback received with regards to the iron sound. 

    11. Change SENS from 1 through steps to 9. Leave TH on 0. Note chattiness from high settings.

    12. Change TH from minus 9 through steps to 0. Note the correlation with regards to depth, density and size. Note SENS and TH are a balancing act to achieve varying results, size and depths the user wants. 

    13. Do some circles with your eyes closed to concentrate on audio feedback alone. 

    14. Experiment with different swing speeds over a target. You will find the optimum swing speed for the Tarsacci which differs from most other detectors and when correct will give a clean, clear and distinct target sound. 

    15. This leaves you with BLKS, TRACK to use/not use in the field. Note that by employing BLKS it is an extra filter used to settle “chatter” down whether you are in black sand or not. 

    16. FREQ of 6.4, 9,12,and 18 are sensitivity ranges related to size and conductivity. Experiment. 



    Basically by using settings on minimum and then maximum it will give you a good feel as to how each setting is integrated with another and the cause and effect they have in being altered upon other settings as to the overall balance of the Tarsacci and results achieved. Too high a SENS setting will give you an unstable chatty unit. Do not ever underestimate the power it has to surprise you.... even if the settings appear low. In time as your confidence grows you will find the optimum site setting no matter where you hunt. Just remember THE MOST IMPORTANT is to get the balance correct between GB and SALT to run silent and your swing speed. Thankyou for taking the time to read the above. It was hard to try and keep it short without overwhelming the user to “balance” all settings. This is but a brief insight into Tarsacci technology, exciting!

    Problem With V3i 10” Stock Coil

    in White's Metal Detectors

    Posted

    The V3i is my elderly friend,  he just purchased it new last last year w other coils and never put the big coil on until recently. Yes Steve, looks like a bad coil. There’s no stamping or anything on the inside of ears. There is a number “V1” stamped on the outside of one of the ears though. You think  Whites will still replace this coil?

    Thanks
