Can anyone recommend an aiming light for a large diameter (Subsea Mk150) strobe. Historically I used a Underwater Kinetics (UK) Super-Q lite with a rubber holder that strapped to the strobe. I find now that UK no longer stocks the nicad or any other parts for the light. Is there a comparable product sold by any other company that has a holder and narrow beam light that will attach to a large diameter strobe? Alternatively if anyone knows where I can find an old Super Q nicad I'd be delighted to hear from you. UK told be it is no longer in production. Thanks in advance. Les.
