Sea & Sea YS-03 Solis Underwater TTL Strobe Package
[S&S-03126]

I needed a replacement strobe for my Olympus TG-4 camera. I wanted a simple to use slave strobe that is light to handle, reliable and robust. Given you also need a fibre cable and can never have enough flex arms, the bundle was also attractive. The base lets the package down slightly, but its functional and I tend to prefer to customise my own anyway. I've probably done 20 dives so far and no misfires. This meets my needs perfectly. Some sample shots.
