Best hand held nail locator please.
Hi Guys and Gals,
There is probably this info here already but I cannot find it.
The Kalbarri Men's Shed is looking for a hand held nail detector so we don't bugger our nice new Planer/Thicknesser.
Any help will be greatly appreciated.
Thanks.
Bob Wemm.

Our shed and I have a carbtech detector
https://www.carbatec.com.au/workshop...with-carry-bag
There's no problem with the detector, the problems
- getting the members to bother to use it and
- getting them to use it properly - slowly and carefully - not on top of the thicknesser, and after removing a mm or two of wood, look again for bits of metal.
One of our members have gone through out timber stocks and turfed out anything that even looks like it has nails in it.
This will probably save more agro than the detector.
A while back I looked into the guts of metal detectors. There are lots of hoary claims which are basically bollocks and from what I was able to glean they all used the same basic circuit - just packaged into different shapes and sizes. The security type detectors are not as sensitive because they are looking for weapon size objects.

I use one from Wizard Proucts - Little Wizard Metal Detector. As BobL says, slow and steady and recheck at intervals.

Early this year I had a need for a detector and bought a $14 one inc delivery from HK. The delivery time was circa 21 days from memory. During this period I had an urgent need for one and went to Carbatec to buy it. It cost $80 plus my time, fuel etc to get there and back.
The upshot was, they are effectively identical visually and operate the same!

Hi Cava,
Do you have a brand/model number (or an eBay supplier) for the HK version?

I too have the Carbatec's metal detector and agree with Bob's comments. The "best hand held dectector" is one that gets used.
I have tested mine and have found that they do have quite a limited depth of penetration, i suspect <1cm (depends on wood) so if you're planing/thicknessing more than a few mm its a good idea to recheck every now and then. If you're re-sawing then inspect the wood for nail/screw holes before sawing.
Also like every test equipment,before use test it and make sure they work before relying on it. its a simple case of scanning an object with a known metal object embedded.

Just reading through this and wondering whether a stud finder set to metal detect would do the job any better. I have a Bosch unit that's a classic to get right as a stud finder but it could/should work for nails. Will try it over the weekend

The problem with all small metal detectors is that you have to have them near the nail to find it. The larger the detecting coil is, the better the chance that it will have the nail within its locating zone.
The best would probably be a coil that you have to pass the timber thru it, as it would guarantee that the metal is within the coil.
My preference is a rare earth magnet hung on a long thread above the timber. As you move (zig zag) the timber past the magnet any metal will cause the magnet to deflect.

We have a Garrett Super Scanner at work (the one you see at airport security) and it does a pretty good job; we can't use it on the floor as it tends to pick up the rebar in the slab . Not cheap though...
