Blumags Compact BM100S Underwater Stainless Steel Magnet W/ Carry Case (220 lbs Holding Force)

Stainless

We provide supreme corrosion protection by encapsulating the magnetic core in a Ni-Cu-Ni coating, and a strong and thick epoxy layer on top of that. In addition, the housing is made of stainless steel, ideal for underwater use.

Neodymium

At the heart of our products is the world's most powerful magnetic material - Neodymium. Outperforming all other commercially available materials on magnetic flux and coercivity, this material is the obvious choice when holding force matters.

Multifunctional

Any piece of equipment can be firmly mounted directly onto the magnet. The rigging point can be easily removed and replaced by your own equipment. The Flipper models provide two threaded holes, while the Willy models come with three clearance holes. 
Compact and handy, the Flipper™ series makes a perfect companion underwater. Use it to anchor yourself in position and free your arms and legs to do useful work instead. Hang your equipment off from it, secure a rope, or remove the lifting lug and fasten whatever you would like onto it.
