Blue Fin DivingDive center

Blue Fin Diving is an inland dive shop just off the high street in Sidcup, and it covers a surprising range for its size. The PADI 5 Star Dive Center fills tanks with air and nitrox, supplies oxygen for rebreather divers, and teaches technical diving under PADI TecRec, rebreather, freediving and adaptive diving.

Training runs seven days a week to fit around people's lives, with small groups of three students per instructor. Equipment sales and servicing are on site, and everything is taught in English.
