I'm responding to Michael Blood's comments about
the magnetic cubes offered by one of our list members.

I see no practical reason to have a scale cube
made of magnetic material. Out in the field, it
would have to be isolated from any electronic
devices like GPS units, cell phones digital
cameras and laptop computers. A magnet of this
size and power can ruin electronic devices
containing chips and other sensitive components
quite easily. Back home, in the lab or in the
studio, the same situation exists. Very often, I
get my camera really close to a specimen and I
wouldn't want to put an expensive camera at risk
by using a scale cube that is also a neodymium
magnet. Seems like an avoidable accident just waiting to happen.

One more thing. How many of you have tried to
keep a "neo" magnet clean? It is next to
impossible to get all the little bits of
attracted material off of one of those buggers
once they've come in contact with each
other. When used out in the field, they fill up
with black sand ( iron and magnetite particles)
quite quickly. Maybe someone else can tell me
how to get all of these particles off of a
magnet, but I've never been too successful at it.

Personally, I use the cubes offered by Rob
Wesel. I an not a scientific field hunter with a
need to show compass directions of in situ finds,
so the plastic ones work fine for me.


Best,

John Gwilliam
