Really cool, what year do you think that lock is?

Before the sun broke out in full force today I did a quick run about 1 1/2 hours to test out the Nokta waterproof headphones on my Multi Kruzer. Ran it at 19khz looking for small jewelry, found 2 1/2 earings, cruddier one might be gold brighter one is plated. This pond is brutal with iron as you can see the black chia pet looking thing on the side. It is a hard drive magnet I stick in my scoop to catch nails and bobby pins. You can see some of the rocks that also stick to it. My GB was low to mid 90's so ended up using Gen Mode in the quieter areas and 3 tone for the most part. Headphones are little better on audio than my Garrett waterproof ones, audio sounds similar, maybe bit less tinny but you do need to kick up the volume. I usually run the machine on 3 but use 10 on these. Vibrate mode proved to be useless because of all the iron in the ground there as it just constantly runs. Bottom line if you got a Kruzer or Amphibio, well worth the investment if you plan on splashing around.

I prefer my analog in bad ground over my digital machines. just much quieter to run.

I use one of these for various tumbling including clad. It handles 18lbs at a time (including media). Walnut shell seems to work good on clad. I used the fine and ran it for 4-6 hours. You can pay a lot of $$$ on a tumbler and they all basically jiggle the contents around. https://www.harborfreight.com/18-lb-vibratory-bowl-with-liquid-drain-hose-96923.html

Well done!

This sparked interest for me as there is a patch of land next to local puddle that was used for bbq's from the 60's-80's. Dirt is hard packed and a complete bed of aluminum square tabs, ring tabs, beaver tails and can slaw. I had cherry picked out the copper, silver and a handful of nickels but there are just way too many aluminum targets to pick through for any gold. I have never worried about a crushed can, those are usually large and loud enough to ignore on just about any machine.

So what would be the numbers on id's with an xp machine with raw numbers? Anything like the Gold Racer? Maybe split this thread to another in the right category?

XP machines normalize their ID's as far as I know. If you change frequencies your id's for a given target is pretty much the same, correct? That chart is the raw unfiltered id mapping from Nokta/Makro user manual and is same chart used in both the Gold Racer and Gold Kruzer. These are prospecting machines with higher frequencies than the MDT 8000 and others. So Are the ID's the same across all frequencies on the MDT? I don't like boxes 🙂

That brings me to another question. If you take the natural response of a single frequency machine, would a gold machine like the Gold Racer be better in high aluminum trash areas for cherry picking out gold? I am sure general coin shooting would be trickier as you start to lose the gamut on the higher conductors. Here is the ID scale on the Makro Gold Racer @ 56khz. I have a stupid thought in my head that I maybe able to use that to cherry pick some parks here that are just blankets of aluminum. I have sniped out the easy copper and silver but the can slaw is brutal.

Can you hear the iron off the edge of the coil? I do that quite a bit to check on bottle caps when coin shooting. Get bit of a grunt on edge tip or tail and I move on.

That's a lot of square and pull rings, where you in the water? I usually find those along the towel lines but in the water I find more of the steel caps as people like to fling them from the shore. Snag a piece of aluminum tube, I use McMaster Carr www.mcmaster.com for small quantity stuff and industrial cool stuff. 6130 should be fine for that and you can just drill a hole through a piece of wood to work a small bend like that without damaging the tube without a bender.

If you plan on an all terrain machine, one that can be submerged under water as well used on land, plan on waterproof wired headphones. Wireless headphones are great until the control unit is dunked then you have no signal.

Imagine texting on a rotary phone?

Is it possible to build one of those and have it run at 40khz-60khz? How difficult would that be?

What would be nice is if the companies use standard bluetooth so any bluetooth headphone and pinpointer for that matter would work with bluetooth compatible detectors.

Pure nickel or near pure nickel will stick to a magnet like the tiny denmark coin which is probably similar to the transitional Canadian coins. Odd how once alloyed, nickels turn to trash in the ground.

Top 2 coins stick to a magnet, one on right is steel as I checked by the date, other is either steel or pure nickel (nickel alloys won't stick to magnets). Bottom ones are silver. You can tell by the color difference if the coins not too beat up.

I had a problem similar to that when I was shipping some items out. Seemed the TSA might be flagging it or customs so it's going around in circles and back to the sender. Was it sent so you pay duty fees or is the factory just sending it out? Thinking it wasn't declared properly when sent. I would like to ship my diggers out internationally but don't want to run into the same issue with customs. What is ironic is they flag a garden tool but have allowed the majority of fentanyl to be shipped from China into the USA without question!!! Figure that one out.

Nice. My last silver looking Canadian quarter got me all excited until it stuck to a magnet on my bench LOL.

Is the Canadian coin silver or steel? I found a few steel quarters that were Canadian and on that was silver and much older. Not sure what year they started to use steeL A magnet is the easiest way to check.

Welcome to the forum. Great place to share ideas, tips, tricks and finds.

Bug repellent is usually enough here. Mosquitos are pretty big...

Think the id is just course but the machines ability is much finer so by hitting on the break point of the foil he is still able to hear the gold. Nice to see the machine isn't limed to the numbers it shows and you can do such a fine adjustment.

The UPS keys might explain the late deliveries!

If those bullets are mid 1800's they fetch a buck or 2 ea. Noticed the pocket watch there too. Reminds me I should go through mine but getting lazy these days.
