With deeper targets you’re looking for repeatable signals, and when you change angles on it you want to hear the same repeatable signal. Of course it’s not always that simple, because it depends on how the target is sitting (on edge etc), and if there’s anything else (metal) nearby. The more targets you dig, the better you’ll get at judging things - take notice of what the signal sounds like and the numbers are doing BEFORE you dig, and then you’ll start to notice patterns… Good luck!

Thanks, really helpful.

It’s a sweet, sweet sound! Thanks for watching!

Thank you, and thanks for watching!

Thanks for watching!

Absolutely! HAPPY 2025 to you too!

Haha yeah - definitely a much better find! 😉

Happy New Year to you too!

Welcome, and thanks for watching!

Technically I guess it is shorting out. However the voltages (and amperages) involved are too low to cause any kind of issues, and the flow of current results in the electrolysis process, which is what we want.

As a general rule, that is true. These coins have no value to begin with, so there’s nothing to lose. As mentioned in the video, I ONLY do this to badly corroded coins so I can identify them.

I’m glad you found it useful. Good luck!

I have tried aluminium, steel and iron, but not magnesium or zinc. I’m still experimenting, but aluminium seems to give the most consistent results. I’d like to find out if any of the sacrificial metals cause discolouration of the object being cleaned.

Thanks for watching!

They were already more damaged than anything I could do to them, so only really interested in identifying them.

Thanks CBK - That’s a good tip about the CLR, thanks for sharing! I’ll give it a go and do some comparisons.

ah, one more thing: Electrolysis on such a small scale in a normal sized room is probably no issue, but you should still open a window or at best put your electrolysis bath in front of an open window to vent out the hydrogen. if you do this in a very small an badly ventilated space and forget about it it is possible to get the hydrogen content in the air high enough to have an explosive mixture.

I agree that it’s absolutely fine to touch the live wires with 12VDC - I was just being ultra cautious because as a general rule, it’s good practice to disconnect from power when working on anything electrical…

Yep - I should have mentioned working in a well ventilated area - forgot that tip…

Glad it was helpful! Thanks for watching!

Cheers mate! Thanks for watching’

It's a common problem, but unfortunately there's no foolproof method to prevent verdigris from returning completely. I’m still on the lookout for a solution. For me, it’s mostly about identifying those really badly corroded coins.

Interesting! I’ll have a look around to see if it can still be purchased - it sounds like the perfect cleaner for copper and brass coins!

21vdc power supply would be fine. I usually do 3-4 coins in one bath, and then discard the water and replace with a new mix. The water gets discoloured quite quickly, but it’s ok to use for several sessions. No matter what combination of power supply and solution you use, the main thing is to check the progress often to ensure you don’t “overcook” the coin and discolour it etc.

Thanks for watching!

Thanks for watching!

Good question - I’m still looking for an answer to that. It’s probably a case of finding a clear product that seals the coin and stops the oxidisation process.

You're welcome - enjoy cleaning!

That was actually a leaf - just like the hundreds of similar leaves you can see all over the ground. If I was going to plant something, it’d be way more exciting than an old penny with a hole in it… Merry Christmas! 🎅 🎄

@coilsandcoinsdetecting lol where were the others that was the only thing that looked like that in the video.

I find it’s much easier to factory reset each mode individually too.

Interesting! Thanks for your comment! I’m still leaning towards these pennies being repurposed as washers, due to the fact there were two the same, and they were close to each other. It’s always fun finding something a bit different!

Yes, I’ve heard about this superstition before. I also believe they would often use a coin dated the same as when the house was first built, and nail it to the rafters or near the threshold somewhere for good luck! Thanks for watching, and for your comments.

@coilsandcoinsdetecting nice, didn't know about the date thing!

Exactly my thinking with these two! Makes good sense, and being resourceful was the name of the game, especially when you lived on a farm or out of town.

You're welcome!

Thanks for watching Dan! I really enjoy using the manticore - it’s amazing how deep it goes on the beach! Good luck with your hunting!

@@coilsandcoinsdetectinggrazie mille alla prossima 👍

Damn, I stopped digging too soon! 🤣

Thanks, they are!

Thanks for watching! I bought the hand digger many years ago off eBay for about $40, but it’s no longer available to buy unfortunately! The black widow long handled digger is available from ROE ENGINEERING here in Australia. Highly recommend it! Tell them Steve from C&C Detecting sent you and you might get a cheeky 5% discount!

Thanks, love your work.

Cheers! Always nice to find a few coins!

No problem 👍
