Some are more brittle than others but ALL rare earth magnets are brittle - it is just how they are made - by sintering powdered metal. Some come in a protective cup and are called Pot Holders. I would suggest 20-30mm dia by 5mm thick with 5mm countersunk hole & N48-N52 strength ...

Ahh but first I would have to figure out what I wanted and figure out how to design it for 3D printing, then learn Autocad then design the stand, then figure out what plastic I needed and then what 3 D printer I needed then buy them then learn how to use it then learn G code then programm the...

Can you give some examples of the different depths on same targets Steven?

Possibly a previously undiscovered use of the word "simply" ? :)

I have had an InReach Mini for 3 years and use it weekly from Apr to Oct each year when prospecting inc a trip up CQ/FNQ each year. If you want it as a satellite SMS service & ultra basic backup point-me-home-GPS then it works perfectly fine and I would recommend it. Cost $450 +...

So after running down the 2 batteries over a few sessions I let them charge longer on the 12v charger with the red & green flashing and eventually for both batteries they ended up charged - solid green . So since it worked eventually I then put a cigarette lighter plug on the cable - who the...

The red layer looks like spiral wound reinforcing filament rather than a copper sheath, which is normally mesh wound. If that is the case then the coil should still work fine as nothing electrical is damaged. Mechanically though it will need taping from top to bottom else you will...

If you are only looking in a 50 x 50 m area and one person buried it by hand relatively quickly then 2m deep is prob max likely depth. If you are fairly sure your efforts wont attract undue attention you can start cheaply & work up to the more expensive methods. 1st : A big coil or a 2...

Simmo, is Cannibal Ck pay to detect ?

Once I saw the red flash i never let it run much longer. I will give letting it charge longer a go. I dont mind the Christmas display as long as it ends up charging. I was wanting to put a cigarette lighter plug in place of the clips but figured I'd better leave it OEM until i know what is...

For some reason I am struggling to charge either of my 2 genuine SDC2300 Lithium batteries using the 12V charger. No problem with using the 240V charger - plug it in, get flashing green light and a few hrs later have a solid green light & good to go again. But when I use the supplied Minelab...

Hmm , cant say I recall ever having that "1/2 response" for a target. Try swinging at 90 deg ie E-W if you were swinging N-S before to see if it is some weird target orientation thing or the detector itself. Do you have that 1/2 response with a reasonable signal or is it a weak, limit of...

Yup my fav coil. Use 90% of time. Exactly as Nenad says - nearly as sensitive as GK19 and nearly as deep as GK26C but handles mineralisation better than GK26C

Yes of course, on repeatable localised threshold waver. But on any even half decent target once you start scraping then you generally only need to remove 25mm to get a flickering number, another 50mm for a solid number. Exception is if you have a sub grain target on surface which is so small...

Huge coils are a PITA unless ground is flat and devoid of sticks bushes etc I have never had the pleasure of a fistfull of gold coins to bury, or even silver for that matter.:) For any targets of exactly the same geometry the most conductive will be detected deeper by any machine so Ag deepest...

...and 10 :1 diluted brick acid ( hydrochloric) will dissolve most of the rest of the non valuable nonmagnetic silver coloured metals.... If it survives caustic and acid and is non magnetic but still soft enough to mark with a knife then it is interesting enough to get XRF done at your local...

no prob detecting my pallasite & siderite slices :) only wish I had found the original myself...

OldHand came up with the idea of using a 6:1 vernier mech on the GB pot. I tried it & liked it & told Karelian who told the guy in the USA who now does the conversions. https://www.prospectingaustralia.com/forum/viewtopic.php?pid=553435#p553435 Nesral then suggested a multi turn pot for both...

regardless of GB on or off, set pulse delay to 10us for small gold and for small coils 8" or less. for coils above 12" set pulse delay 12 or higher as needed to settle her down. always turn gain up as far as you can whilst maintaining stable response. youshould be able to run 6 gain anywhere...
