Firing Above-Water Studio Strobes

The Trigger Fish – Radio Trigger Housing is designed specifically for underwater portrait photographers who want to fire their above-water studio strobes with precision and reliability — bringing professional lighting into the underwater world without the limitations of built-in underwater flashes.

“I am an underwater and portrait photographer based in New York State, what that means is that nine months out of the year my Underwater pools are all located indoors, and often with less than optimal light.  Previously I was using a system with an on camera flash that optically triggered my above water strobes, but depending on my position in relation to the modifiers on the strobe, it wouldn’t trigger reliably.  It was so frustrating to miss a great shot!!

Another pain was adjusting the strobe power- I had to physically haul myself out of the water to go change the settings on the unit!That was until Brett told me about his Trigger Fish!  It is a perfect solution for anyone who shoots portraits underwater and wants to be able to use their strobes above the surface!  As a bonus- changing the strobe power is so easy! Just open the box and change the setting just as if the trigger was mounted on my camera!!  10/10 recommend!”

“It has truly elevated my underwater portraiture work. I’ve been a fan of Brett’s photography for years and even attended his workshop, where I learned to use above-water strobes to light models underwater—something I was hesitant to try. With his encouragement and guidance, I invested in an above-water lighting setup for my business, and I couldn’t have done it without his radio trigger housing. His craftsmanship is top-notch, and I can’t wait to keep using it for more underwater shoots!”

“Firing an above-water strobe from underwater used to be a real challenge for me. My DIY solution got the job done—but not without headaches. Once I tried Brett’s TriggerFish, everything changed. It works like a dream, making it so much easier to capture the kind of breathtaking images I couldn’t have achieved otherwise.”

With Trigger Fish, underwater portrait photographers can finally unleash the full creative power of above-water studio strobes — safely, reliably, and beautifully beneath the surface.
