Magnet in waterscoop

I always had a cheap refrigerator magnet in my old RTG waterscoop, but I have since bought a nice Stealth scoop, and have yet to put one in it. I am curious as to how many others have used a neodymium magnet in their scoop.I am looking at buying a rectangular style that is 3 3/4 x 1 inch that has 2 holes to fasten it with. My question is, are these magnets too strong to be around a detector? I don't really know how far the magnetic field reaches? I just want something that keeps the hair pins and such stuck well! For around $30, this one will fit my stealth very well.
It is a grade N42 and I believe it has around 150 pulling #'s.
 
$30, 150# pull and 2 lbs...a bit aggressive for me.
I use a ceramic 1X2 magnet unknown pull but only 2ounces.
Harbor Freight sells 2 for $.99 and Radio Shack sells one for $2.99.
If your Stainless Steel is NON-magnetic, a dab of RTV - Shoe-Goo
or the like will hold a magnet in place.
 
I assume you are using a PI, i use an Xcal rarely a need for the magnet. Bear to keep in a WORKING scoop.......... so id go cheap. Tried a earth magnet once with a hole in the middle........ broke apart like the first week. Your best bet is some cheap computer magnets...... because nothings going to hold it in there long. The sand and scooping takes it tole.

The magnet is actually only 5.55 oz. I guess I forgot that this scoop will attract the magnet. Probably no need for fastening holes. My old scoop was aluminum.
Just want something stronger than what I was using.

I run an Xcal 2 and the At pro. I hunt fresh water lakes, and bobby pins and some deteriorated bottle caps can be a nuisance. I do have access to some old computer equipment, so I may go that route. I just thought the rectangle neo magnet would fit nice at the tapered back plate of my scoop. I am not afraid to throw $30 towards the magnet, I just want to be sure I am not going to chance wrecking a detector.
 
I have magnets in all my scoops wet and dry sand scoops.:detecting:
 
neodymium magnets with the nickel coating will disintegrate in a little over a month of 5 day a week hunting. Second time I tried rubber coating them and it took a little longer but now they are self destructing.
I will say, the bottle caps just love those magnets.

Break open a hard drive. Theres 2 in there.
 
So the computer magnets won't discinagrate? What composition of magnet works best for staying together, while performing excellently.
 
I pulled apart a couple HDs a few years ago and removed the magnets that stabilize the read/write head. I still have one on a scoop I don't use very often. In theory they should last a long time even in salty environment, but if the nickle plating has a flaw or fracture it will break down in a few weeks or months. They are surprisingly powerful and can be impact damaged or scratched.
I just noticed a dozen or so HDs in the garage this week. I just may go magnet fishing!
 
Hi Ron, Like WaterWalker, I have the CERAMIC Magnets from Harbor Freight in ALL My Scoops, and I DON'T Drill any Holes!! I have been USING these Magnets for about (3) YEARS
NOW, and They Work G-R-E-A-T!! I just USE (2) Small ZIP TIES, Ones about 1/8" or 3/16" WIDE, and make sure they CONNECT at the BACK of the SCOOP!! Tighten THEM down with a Pair of PLIERS, that will CUT the EXCESS ZIP TIE Off, after YOU get IT Good & Tight!! The ZIP TIES will last about a YEAR or More, and REPLACE the ZIP TIES as NEEDED!!
They come (2) to a Pack at Less than $2.00, and THEIR Very S-T-R-O-N-G!! Hope this HELPS, Les Robinson.
 
use a magnet in the scoop just for PI detector ,

really free the magnets are in the old hard drive.

seawater magnets are not for a long time ... it consumables ....

ps: the main thing is a - good scoop! :)

The N42 magnates work great. The nickle coating does not last long but the magnets keep working fine. I have used mine for three years with no problems in my Sunspot scoops. Only problem is that Sunspot uses really good grade of stainless so magnet will not stay attached well. The trick is to place one magnet to the outside of the scoop, then place another on the inside of the scoop so they attract to each other. They will never come loose again. Careful not to get your fingers in the way while bringing the magnets together. They really help to attract junk jewelry that is small enough to slide through the holes on your scoop. And no, they will not affect your detector adversely but I would not put the magnets against the control housing of your machine...Stuart

Thanks Stuart. That is the answer I was looking for. I have access to plenty of old hard drives, so I will just try using the neodymium's from them first. Great idea with putting one in and one outside the scoop! I guess I won't be out anything if they break or somehow come loose and go missing. I usually drag my scoop along as I search, so I will likely also be removing some target masking junk metal this way.

Every now and again I get that spitty overload with mixed tones, on the Xcal, that ends up being a set of car keys. I imagine I will find a lot more of these such items, attaching themselves to my scoop as I'm going a long.
Thanks for all the replies!

Ron.
 
You could also glue the magnets together for added strength... depending on how the magnets and scoop holes are shaped. To seperate them you would probably have to melt the glue
