We get a lot of phone calls from folks asking “will your Underwater Retrieving Magnet pick up brass?” People also ask if the Underwater Magnet will pick up keys or military ordinance.
The short answer is this: When ferrous metal objects are submersed in water, they actually are easier to pick up, per pound, than when they are above the surface. The water makes the objects more buoyant. However, unless the object is ferrous metal (contains iron), the Underwater Magnet will NOT pick it up. In the case of brass, the Retrieving Magnet will not pick it up. Keys containing ferrous metal will be picked up.
We also get folks asking if the Retrieving Magnet will pick up rings (usually wedding) and the answer is “no”. Sorry if you lost your wedding ring overboard but unfortunately the Underwater Retrieving Magnet can’t solve that problem.
