Nice job and it looks like it will do the trick.

What type of printer are you using?

What size of scoop will that fit?

Fits my RTG scoop that has a 4 3/4" id.

Picked up a single extruder large format Anycubic Chiron that can handle 16x16x17 approx. Was sceptical on the printer at first but it is actually incredibly reliable. Bang for the buck its a great printer. Used an SLA printer for more than a decade so going over to FDM was fairly easy as it is more like a cnc machine.

Nice little piece of engineering. 👍

I'll chance a prediction.... 🤔

That set of diamond earrings it catches will buy you a new Equinox 1000....🤩

Man made diamond 😞 might pay for the gas as I am walking distance to the pond haha.

Cleaned off the scale on the inside of scoop with a wire brush and used some 3m heavy duty mounting tape. Gorilla tape would probably work fine too. Seems to hole well. I chickend out on the rivet as it would leave a point inside that would get in the way and the plastic may break through. My scoop is pretty bent up from years of abuse so zip ties didn't work.

Making the tool needed for the job yourself is the sign of a dedicated craftsman!

More like the frustration of trying to keep a tiny target on the end of a scoop when your chest deep in the water motivated me to come up with some sort of solution.

Was someone on this forum a while back that was showing off a custom OO coil on some machines. That Bi-axial reminds  me a little like that.

Please don't tell anyone (we're trying to keep it under wraps) but that spiffy new coil is available on Amazon:

https://www.amazon.com/Fisher-inch-Coil-Triangulated-Bi-Axial/dp/B09SNVRXHC

Apparently only at Amazon, as far as I can tell. Limit 2 per person.

If anyone can purchase, on the open market, the new Fisher MF detector in 2022 I will send them one of my paychecks. Offer good for the first person who can show proof-of-purchase. I'm not sure why we keep aiming for the foot and pulling the trigger but it sure makes for sore feet and a red face.

 

How does that coil handle iron infestation compared to a concentric?

Now thats what a good day looks like.

Take a loop to that big rock and see if there are any refractions or not. Should be easy enough to tell if it's a diamond not not. Big stone like that might even be etched if it's real.

Heart a ruby?

Stuff I used isn't super durable on the edges but surface is holding up well. Much softer than what is on other machines.

Mouse pads are a little thick on this cuff and too hard. Tried that.

One of the things I was never crazy about with the Nokta Multi Kruzer is the arm cuff. I have repositioned it a few times and found all the way back works best but still bothered me. For some reason they don't put any padding on them so I picked up some adhesive back neoprene sponge foam from fleebay:

I first tried 1/8* and it works great, easy to put on but can tear easy off the edges. Wasn't sure how it would hold up but on the cuff it works great. Descided to toss an extra layer on and it stuck fine and trimmed off the edges. Super easy to put on and softer than what the other manufacturers use.

Because you can apply it in layers it is easy to beef up spots in areas you may want.

Big coils will give you good ground coverage but if targets are too dense or there is iron in the area you can be more prone to masking. 11" stock should do the trick for that type of hunting.

Water hunting I used to use my 12x11 but find a smaller 9" concentric better. Most VLF's in the 15-20khz are plenty fine for jewlery hunting with the right coil.

Your nox should do just fine, doubt you will really see much difference other than being in the hole for $1600.

Kind of like fishing for sunfish when the trout aren't around, all still fun.

Davide, have a couple of questions about your discrimination. Do your pulltabs disc. out Before or after the nickels?

TC-AZ

Pull tabs always above nickels. I get tripped up on half pull tabs (ones cut by mowers) as they usually come in really close to nickels or sometimes just under.

Detech Arrow isn't available for the Nox. Trashy areas your 6's should do fine. I find jewelry with all my machines though the smaller earrings and chains are trickier to find. Higher frequencies help but overall don't plan on picking them out at any depth other than an inch or so at best.

One thing that helps me is I pay attention to the type of trash and the numbers they run or their sound on the Tesoro. Trash like can flip tops tend to be similar in areas. Where you end up doing more dig all is with foil and tiny aluminum.

Can slaw signal will carry bit longer so when you get a hit, lift the coil and see how far it still picks up and make a mental note of that. Gold drops off faster than alum so it may save you a few junk digs.

Almost all the gold rings I have found were below nickel range. Beefy platinum comes in just above and class rings are up near pull rings. Thin silver rings can be in around penny range and silver chains and earrings can be below pull rings.

More activity in an area (more trash) the more likely you may find something.

You can identify Chinese coins here

My Detech Arrow gives me similar depth on my AT Gold as the stock AT Gold 5x8" coil on a coin size target. 

https://www.calgarycoin.com/reference/china/china8.htm#chai ching

Thanks Phrunt, thins it' CH'IEN-LUNG, AD 1736-1795. I have another I found ages ago and will try to find it and look it up.

The Arrow coil looks pretty cool, might be a good option.

Thought you would get a kick out of that.

Been thinking of getting a small coil for it, not sure the 6.5x9 concentric or the 5x8 dd. DD probably better for coin shooting and the AT Pro isn't a depth demon. Coil I used was the stock one I had cracked then repaired.

Trouble I have trying to identify it is I don't know which way is up 🙂

Few years ago I found all these nickels in a local swim hole, most were in a small area maybe 10'sq. Figured someone was trying to drown their kid and stuff their pocket with them.

I made one out of flat stock of ABS and formed it with heat for my Multi Kruzer that loved to flop over. Stand should be a bit wider than the stock but not be in the way when you swing.

The Nokta scoop might be worth checking out. Regular sand scoops are great in the water to sift out the sand but wet sand on the shore you end up just dumping it on the side rather than shaking them out. I tend to favor my RTG basket scoop for beach combing. The Nokta seems to be a hybrid of sorts between a regular scoop and basket type. Handle comes apart for portability.

One to ask is Monte. You could pm here or if your a member on AHRPS could ask there. The notch discrimination might be the same circuit used on the Cortes.

It never crossed my mind it'd be OK on the Simplex as the Simplex target ID's are quite reliable for shallow targets, I bought it for my AT Gold and avoided the Simplex due to the poor target ID on the Simplex but I didn't think about the coil's focus is shallow targets.  I quite like it on my AT Gold though and it's very sensitive to small gold considering the detectors frequency.

You did well with the Arrow and you've perfectly used it for and demonstrated it's strong points.  It's a really nice coil.

Poluted ground and emi effect target id's. Smaller coils always seem to be more accurate as they are less effected by both. Trend of 11" round dd coils seem more for marketing than practicality. I like my Superfly but most areas other than low trash fields or the beach it is counter productive around here. I can see how that Arrow would be good where you can nose around the trash fairly well and still cover tons of ground.

Been using a Cors Shrew on the Cibola in school yards and parks lately and am amazed how many targets I can pick out.

Good run there, that buckle go to a chasity belt?

Looks like it does well. Do quarters have same TID as stock coil?

Thats a good chart on buttons, thanks!
