Pulse Induction coin shooting

[Dancer]

Been a sparse year for gold for me this year. My newly overhauled AT Pro has taken most of my hunts. Clad, bling, a little Silver, and a couple of nice pieces that turned out to be 14k gold (filled). No cigar. So been taking the Infinium out with the 8" & 14" mono coils. Of course ya got to pick your spots to run a pulse induction. I got about 4-5 practice fields with fairly deep cover and minimal trash. Besides being able to detect deep, a pulse will grab a shallower coin like a magnet. The Inferno has a couple different tones to help distinguish targets so its a big help for me. About a month ago , stumbled into a penny/dime spill while making a slow pattern across a field. Surface pennies have a sound all their own. So I'm thinking may as well clean em up. After a few pennies, dimes began to be heard mixed in the spill. Small spill 8 pennies, 5 dimes. Finished the lap, started back. Got back to the spill, gave it another swing. Iffy signal, half a pull tab. Another swing, bam, nice hit. Just about 5" down, a 14K medium weight yellow man's ring.
It had been masked by the shallow coin spill. Now how about that ?

Also could have been masked with someone being confused with it being a big shallow target and just passed it up.

Very possible. Sometimes coins laying close together can sound like a null. (Using a PI) Then the human aspect, many of us have passed on pennies near the end of th hunt, feeling a little tired heading for the vehicle.

Pennies will mask just like trash.

Dancer, what is pulse induction? I've never heard of that before. By the way, nice find on that gold ring.

Guys I've sent Still looking as best a description as I could. Maybe some of you could help out with this answer better than I.

Interesting reading,on some of my permissions if i think the rubbish is not a major problem and i think the coins are pretty deep or the ground is highly mineralized then i do use a Pulse machine,but predominately if its just coin shooting then it will be with a smaller coil on.Must admit i have 3 favourite coils one is the Garrett 8'' Mono that i use on my Crossbow,thats a really nice sharp coil its basically the same as the one as the Infinium but from the SeaHunter11.

The other coils are the 7.5DF and Miner John 9x5 Folded Mono on the TDI Pro,the beauty of the 7.5 coil its like having 2 coils in the same housing a 7.5'' and the inner 4'' which is deadly on small gold chains and infact any small jewellery as not only coins,you can also use the high/low target conductivity function which is basically a form of discrimination and once mastered it does work very well,so you can selective in what your targets are but also have the depth advantage that PI machines offer,effectively by using the small coil you can see it as a narrow laser beam so as not too dig massive holes in park environmental manicured lawns etc.In my case thats not a worry as such as mine is mainly used on either pasture of ploughed and rolled.

A Pulse machine is not your everyday weapon of choice for coin shooting,but can have some advantages over a VLF machine,predominately highly mineralized ground,but the biggest downfall in a inner city environment would be the external EMI issues.

If the weather is kind here in the UK this weekend,may take the Pulse out to play for a change,mainly use them for specific deep site use with the large coils,but its also nice some times too use a small coil on and do some coinshooting.

Mega, The one thing I have been dealing with is the loss of depth when using the coin settings (gain set at 1 to 5) which does discriminate out all iron and focus on coins. What are your settings and depth ?

Good question and i can only answer it as use my machine in my UK locations,i dont use mine for coinshooting in say parks or manicured lawn environments,predominately i use mine for deep hoard hunting with the 20'' Mono coil on,but when say i am looking for stray coins from a scattered hoard in bad ground conditions that a VLF machine just wont work then the TDI is the preferred weapon of choice.

As mentioned above the TDI does have the high/low target conductivity function which works well i you use it in parks or your tots lots,but i like too run mine more in straight PI mode for the raw power which equals of course more depth,and in my farmland conditions this work better for me than say someone using one for coinshooting in a park,this is my personal opinion a Pulse machine although can be deeper is the the best option for coinshooting i dont think.They have uses and of course can be far deeper than a VLF for specific tasks in bad ground,but also far from being perfect for just popping down the local totslot for a few dimes or what ever you folks find.

A Pi as we are all aware excels in hunting for gold nuggets and beach work,trouble is i dont live in Aussieland/Arizona or near the coast so it will never be used for those 2 major detecting scenarios,but in the UK we do have hoards and these are mainly deeper than normal VLF machine can reach,this is the environment that i then use my TDI Pro and i feel its the right tool for the job,once you suspect a scattered hoard is in the area and coins have been dragged up by the plough then that is when i use the TDI with the small coil to pick up the scattered coins and then use the very large coil to try and locate the container,of course that is if one is still in the location.So yes it is used for coin shooting in a way and of course locating very deep metal items as well like we hope a container,hence why i tent too use the machine more in straight PI mode than the conductivity side of the machine.

Mega, Thanks for the reply. I fully understand now your use for the TDI and by what you are hunting in requires all metal mode for the maximum depth in seeking the hoards of coins. The TDI is a great PI unit with many values. Best of luck in finding the lost treasures!

It was built specifically for small gold jewelry and nugget hunting. And works pretty dang good for coinshooting parks, school grounds, picnic grounds etc.
With the 7" search coil its a blast to use. See picture below. I have found a heck of a lot of $1 and $2 coins, not pictured, cleaned them up and spent them...LOL

If I were to suggest a manufactured pulse, then a White's TDI with a small coil would be a decent choice.

PI's are not for everyone, they have a bit more of a learning curve. Once you get over the hump, things look up fast. Not all PI's are good are equal. The less controls you have for tuning, your kind
of stuck hunting only beach water areas.

From my website:
For the first 7 months of testing, I avoided hunting trashy school yards, tot lots, parks etc. Then one day decided just to see why everyone says PI's are not good in trash. Went to the schoolyard across the street for giggles, since I hunted it out with many VLF machines, so I thought. Surprise, surprise, started finding coins left and right, lying flat and on edge. Noticed that I was not finding all the small foil that my VLF's would signal on. After several hours, had a large handful of coins. Mostly 5 cent and higher denomination coins. Wasn't picking up a lot of modern pennies, fine with me. Over the course of weeks, the schoolyard still gave up plenty of coins and a silver chain. Took the PI over to some other schools and parks and it performed just as well. It works so well, now grab the PI over a VLF when walking out the door to hunt. Believe that the secret to it's success in otherwise a bad hunting situation at these places is the 7” search coil.
