This original magnifying glass is used by scuba divers from the sand holes in Groningen, the Netherlands, to the seas at the Philipines. But also by marine biologists, in the off-shore industry and for varying explorations.
By using an aspherical lens with a diameter of 11 cm the image distortion is minimal. The magnifying glass is rugged and will be delivered with a snap hook made out of stainless steel.
