Sea & Sea YS-03 Strobe Head

hi everybody my name is pete leung and i'm an underwater photographer based in beautiful okinawa cnc have asked me to come out here to the awesome kume island today to check out their new strobe the ys03 for underwater beautiful easy light lighting photography now the main concept for this strobe is that it's super easy to use automatic ttl lighting in a compact size great for travel taking with you anywhere and easy to use for the beginner great right through to the professional so let's have a look at some features okay so first i'd like to cover just a few points about this strobe that make it really awesome first of all it's got a 20 guide number which means it can punch out a lot more power than your built-in flash can or any led light or anything like that so it packs a nice punch underwater secondly it covers a wide degree of field up to a hundred degrees by a hundred degrees so
