Thanks Mike
It's no problem that the magnets should attract each other and cause
collisions. Mine is very strong and will sit tightly on the metal bar
with 140 lbs pressure. Sideways they are quite weak. I also secure them
with duck tape. Not so much to secure them, but as a pure protection
against wear and tear.
It's an interesting complement tool to metal detectors and properly used
it can surely vacuum the surface of meteorites, at least the ones with
metal content. We have to find a way to hunt those that are
non-metallic. That's a challenge...

Hi Lasse, List
Very nice rake. I had something like that in mind before my magnets
arrived. Once in hand though, I lost my nerve to place them so close
to each other. It was just real spooky and so i rethought the design
and the divided wing setup you see in the picture won out. You may
have worked it out on yours though and so not the worry.
I should explain why i use the magnets right down on the ground and
how that works. Having them ride right down on the top of the ground
doesn't really mean they are actually dragging along. In the first
few seconds they are moving, small gravels have already attached
themselves to the bottom of the magnets. The magnet actually is
riding up on top of these stones. So you will normally see the
magnets about a 1/2" off the ground. As you continue to move the
magnet, those same small stones that have collected underneath start
to work their way to the trailing edge, up the edge and finally up on
top of the magnet. They will ride up there as long as you do not let
the magnet slap on the ground real hard which may dislodge some of
them. I usually drag the cane or the rake until I see that the
magnets just simply can't hold anymore magnetized material on top.
Then I stop and clean it off and go again. One important thing to
note about cleaning the magnets off is that you can pick up some very
sharp nasty little things like fish hooks. One would be well advised
to wear gloves during this cleaning off part, and then you want to be
a little careful. I even found a cactus thorn mixed in with the small
rocks when cleaning off the cane on time. It took a while for that to
quit hurting.
I am glad to know there are others out there with the same ideas for
hunting. Thanks for sharing the picture of the rake. I hope you have
great success and find some really cool stones.
All the Best
Mike in CO
