Britain's Most Incredible Submarine - HMS M1

HMS M1 was one of the most incredible submarines that Britain ever built. Armed with a massive 12" gun weighing 50 tonnes that had been removed from a battleship the Royal Navy were so concerned that it would be copied by the Germans that they kept it secret throughout World War 1. Very sady, HMS M1 vanished in 1925 with the loss of her entire crew until it was located by a salvage team in 1967 and then formally identified by a dive team in 1999. *Support what I Do* Thanks for watching my video and if you'd like to support what I do then please consider joining my channel - http://bit.ly/4kMVqCB You may also wish to buy me a coffee - https://buymeacoffee.com/d33puk *Kit I Use* Note, some of these are affiliate links so help support making my videos: - Gloves are Ansell Alphatec 87-063 - https://amzn.to/4jDHhX4 - Main torch is an Orcatorch D630 - https://amzn.to/4jlT4tA - Backup torch is an Orcatorch D710 - https://amzn.to/4jhddRk - Drysuit is an O-Three Ri2-100 - https://www.othree.co.uk/drysuit-range/ri-2-100-drysuit/ - CCR is an AP Diving Inspiration (XPD) - https://www.apdiving.com/ - Backup computer is a Shearwater Perdix v2 - https://amzn.to/42FXZOW - Reels are by Kent Tooling - https://www.divingproducts.co.uk/ - Cameras are Paralenz Vaquita - Video light is NiteScuba NSV60 - NiteScuba NSV60 - https://s.click.aliexpress.com/e/_onHEKQZ - Phone housing is Divevolk Seatouch 4 Max - https://s.click.aliexpress.com/e/_omJlNKL
