MDT for park hunting

Anyone have good success using the MDT at parks?

My MDT ground balances around 625 at this particular park. I haven't had good success with it. I've pounded this park with the CTX over the years. MDT is getting fooled by small iron just like the CTX. Only dug up a couple of wheaties at 7 inches and a deep V-nickel at 10 inches. Paul has dug up nickels at this park with the ATX at 10 inches so I know MDT goes deep. I haven't dug up any silver yet maybe CTX did too good of a job sniffing out the silver.

Gonna keep trying I know there's more. This park as some EMI and blacksand mode is used. I'll try using salt mode and see what happens.

Hit the park today. Dug 11 holes, 8 had iron in them, 2 aluminum targets and 1 dateless buffalo nickel ay 7 inches. Nickel came in at 12-14 sometimes 7 but when sweeping side to side towards the the bottom of hole nickel came in 22-24. Nickel must have developed a halo. Still getting fooled by small iron like the CTX. Tried salt mode I didn't see a difference in my ground which ground balances at 645 on the MDT.

Settings were: sens 9, threshold -2, disc 0, blacksand ON.

Good job Denny,

Getting an old coin from that park is incredible, a dateless buffalo nickel is still a sight for sore eyes. I would call this part hunt with the MDT a success, I think you and I are the only ones using am MDT for park turf.

Congratulations! You earned that old buffalo for sure!

If you run the sens that high small iron will fool you till your really get the sound in your head of a nail false Vs a legitimate hit..Dont be scared to go down to say 6 SENS if you have to.it will hit deep coins on 6 sens.

Finding that myself, usually keeping the sensitivity around 6-7, any higher I’m getting fooled by iron. The unit does not require the sensitivity to be cranked wide open for high performance depth.

Keith and Aaron,

I had my sensitivity high because I was going after deepies. There were no clean signals many iffy half signals. I slowed my sweep and digging signals that I wouldn't hear when I was sweeping a little faster. Also digging iffy half signals. Sometimes there will be a silver coin hiding near iron like a half dime.

Denny

Denny you in a hunted out area I guess your saying?

I find in areas like that with alot of units its easy to make iffy targets want to be dug yet you know there's something not quite right with the signal before you dig but you take a chance.


I have certain areas like that. I have found on the Tarsacci to go to mixed mode and set disc on zero.

Listen for the approach and departure of the all metal side of the report and see what the smaller blip in middle sounds like.If you cross check in just disc that blip is hard to hear or broken etc from being small and or deep.But it mixed you can hear the roundness of the signal from the all metal side and the faint report makes more sense if if its legitimate or oblong nail falsing.


I have found On the Tarsacci high Sens does not equate into high depth in certain soils.

And too slow a sweep speed can also be detrimental.and too fast detrimental.the Tarsacci Has a sweet spot sweep speed.The falsing will collapse heavily once the speed is right.

I had some good luck using mixed mode. In hard hit sites. I used AM mode too to expose lot of the iron. Mixed mode works. Imo if something is round Tarsacci hits it like a duck on a June bug.

I ran my unit lot of times level 7 Sens.

Hello Denny,

Here’s something I use while Park hunting for deep older coins, maybe other MDT users hitting an old park will benefit from this as well. You’re probably already figured this out, but I’ll still add below maybe others will benefit from this.

Before I started using the MDT for deep park/turf coins, tested the MDT at a test bed of buried coins at different depths at an old park. What I found, audio modulation is terrible with the MDT. It’s difficult to tell a deep coin from a coin not so deep. Tarsacci is very deep, and you know how I hunt and prefer 18 kHz with the Tarsacci. 18khz will enhance the signal of a worn thin silver dime or 1/2 dime, or an old deep nickel and as deep as the MDT detects you’re not really losing much depth using 18khz. Plus, if I wanted can always bump up sensitivity to gain back what little I lost.

Plus, with the MDT. A very deep nickel will ID as a deep silver coin. I find this benefiting the user going after deep coins. They will not miss the older deeper nickels with the MDT, sure other trashy low conductive items and bits and pieces of iron will fool me but eventually an old deep coin will surfaced.

Getting back to the test bed, I practiced listening to each buried coin at each depth until I found the right sensitivity usually 5 to 6 sometimes 7 and right kHz in my case I choose 18khz. Using a certain sensitivity setting, 18khz I can determine a deep coin even though MDT Audio modulation isn’t the greatest. Each MDT user will need to find what settings (sensitivity/threshold) and kHz works best for them to determine depth, what works for me may not be the best settings for others to determine depth from the limited audio/ID information the MDT produces. Many hard core turf hunters may choose a lower kHz for deep silver coins, that’s fine use what works for you. But at least practice with a test bed of coins at the same park you plan to detect, or a park similar to the one you plan to detect.

With the MDT, a user can have good success getting deep coins from pounded parks. It won’t be consistent, but eventually you find deep coins. Stick with what settings work best for you, practice with a test bed, don’t switch from one kHz to another learn only one kHz and stick with it. Changing kHz effects audio modulation, and audio modulation is already terrible so stick with one kHz and learn what the MDT is telling you from the test bed.

Have patience, don’t get discouraged eventually you’ll learn how to score coins from pounded parks with the MDT.

Yes hunted out of easy targets.
I do play around with sweeping speed and have hunted with lower sensitivity before.

I bought the MDT to replace my ATX for water hunting but noticed it's good for relic hunting Paul showed me that. Park hunting I still favor the CTX. I'm used to the smart screen. But I'm going to keep using the MDT until I dig up a silver.

So far dug up 2 wheaties, 1 v-nickel and 1 buffalo nickel from the park.

Good info Paul!
The MDT hits hard on gold and nickels. Yes patience is what one needs if they are going to master the MDT.

I also use mixed mode I find it best for park hunting I'll switch to disc once in a while.
Have been using the MDT for 6 months exclusively. Still learning.

Denny

Thanks Denny,

In addition to kHz, should have mentioned two more settings an MDT user needs to leave alone when hunting parks for deep coins.

Because audio modulation isn’t there with MDT, once they get aquatinted with settings for park turf coins. Try to not make sens/threshold or kHz adjustments while hunting. Any big changes will greatly effect audio modulation so now that audio information an MDT user is listening for will be different. What sounds like a 8” or 9” buried dime may now sound shallow if they bump up sensitivity or adjust threshold or lower kHz. Stick with settings, if MDT user needs to adjust sens or threshold do it in small levels. Don’t mess with kHz, leave it were it’s at.

Good luck,
Paul
