The YS-D1 is a breakthrough in the market featuring a maximum guide number of 32 for 80x80 degrees, 24 for 100x100 degrees or 20 for 120x120 degrees.

Steven R  If I was to get from you (Adorama) the Olympus TG 2, with the PT 053 housing and I have an Ultralite tray and flash arms, would you recommend for a strobe a.)Olympus ULF 2, Sea & Sea YS-D1, or the smaller Sea & Sea YS-01 to use all as TTL with a fiber optic cable?
