Some vertical cavers might use the SMC micro rack for descending, and they might use either stainless or aluminum bars on it. Stainless seems to be preferred. I do not know which alloy of stainless SMC uses, and I don't know how magnetic it might be. Does anybody have a magnet handy?
Some cave surveyors use a DistoX2, and it contains a sensitive magnetometer. This might get screwed up if the micro rack has too much of a magnetic property.
If I am trying to use both items, I might need to park my micro rack a ways down the passageway while I survey. Then I will forget it and it will be lost.
If anybody has both items, could you see if there is any magnetic interaction?
