Trigger Fish Underwater Radio Trigger Housing

Trigger Fish Underwater Radio Trigger Housing

** Trigger Fish setup requires the following from Ikelite (optional extras):

• Ikelite 15ft Extension Cable
• One of the following, depending on your bulkhead: Bulkhead Adapter for Ikelite 5-pin; Bulkhead Adapter for Nikonos Bulkhead

The Trigger Fish Underwater Radio Trigger Housing is a specialized accessory developed to simplify wireless manual triggering of above-water strobes from beneath the surface. This device connects via your underwater housing’s wired sync bulkhead and encloses your radio trigger in an IP67-rated, water-resistant case that floats at the surface. Compatible with common wireless radio triggers—using 3.5 mm or 2.5 mm jacks or hotshoe adapters—Trigger Fish allows photographers to avoid the limitations of optical triggering or built-in underwater flashes. It supports only manual flash triggering, not TTL modes, and is ideally suited for splash zones, shallow dives (up to 1 m), and pool settings

By offering stable signal transmission, crushproof construction, and strategic buoyancy, Trigger Fish ensures that a trigger for flash remains positioned optimally to actuate powerful studio strobes above water. It solves the common problem of signal degradation when attempting to fire surface-mounted strobes without leaving the water or relying on unreliable DIY setups

Main Features of the Trigger Fish Underwater Radio Trigger Housing

• IP67 Water Resistance: Submersion safe up to 1 m for 30 minutes in splash or pool environments
• Floating Design: Keeps the radio trigger aloft, preserving clear line-of-sight to above-water strobes.
• Universal Compatibility: Accepts triggers equipped with 3.5 mm, 2.5 mm, or hotshoe connections
• Durable Build: Features stainless steel hinge pins, rubber O‑rings, and an automatic pressure equalization valve
• Secure Attachment via Bulkhead: Connects firmly to camera housing bulkhead for reliable sync without leaks
• Manual Flash Triggering Only: Designed for non-TTL use; ensures direct, consistent flash activation

Benefits of the Trigger Fish Underwater Radio Trigger Housing

• Reliable Surface-to-Underwater Flash Control: Keeps your wireless radio working above at full range, eliminating lag and missed flashes.
• Protection in Harsh Conditions: Safeguards expensive triggers from water and crushing forces common in pool or splash zone setups.
• Streamlined Workflow: Avoids repeated pool entry/exit for adjustments—flash power can be changed as easily as if the trigger were topside
• DIY Alternative Elimination: Replaces complex homemade rigs with a straightforward, factory-engineered solution.
• Adaptable with Multiple Triggers: Works across brands like PocketWizard, Godox, Profoto (3.5 mm/2.5 mm/hotshoe) and others.
