Siebe Gorman Decompression Calculator

Siebe Gorman Decompression Calculator

Only ever seen 1 original of these before. We found it amongst an old group of Siebe Gorman kit in the bottom of an old divers chest. We liked it so much that we decided to make a limited edition run of 100.

Siebe Gorman & Co Ltd, Chessington Surrey, made these charts and wallets for the MoD divers

Great gift and collectable item
