Ikelite Manual Fiber Optic Transmitter for DL and DLM Underwater Housings Gen 2

Replace your Ikelite flash bulkhead with this compact, independently sealed device, for reliable fiber optic triggering of a compatible fiber optic underwater strobe. High frame rate burst shooting is supported when used with an Ikelite DS160, DS161, or DS230 Strobe and High Sensitivity Optical Converter # 4405.

The transmitter is powered by two CR2032 lithium single-use or rechargeable batteries (not included). The Transmitter has a built-in power save mode which prolongs battery life. Expect at least a week of diving out with average use. It is always recommended to travel with a spare set of batteries.

Connection to a new style flash hotshoe is required, included with DL and DLM housings shipped from Ikelite after January 1, 2025 (serial number 81200 and higher). Older housings require a new hotshoe. Check the Hotshoe Compatibility Chart to see what type you require.

Typical Uses

• You want to use one of the entry-level strobes that don’t have an electrical bulkhead.
• You want to use fiber optic cords to eliminate extra waterproof connections.
• You want to disconnect your strobe cords underwater for some reason. Imagine getting back to the boat at the end of a dive and wanting to shoot some split shots using natural light without having your strobes weighing you down. With fiber optic cords you can pop them off, use our unique quick release mount to disconnect your strobe arms, and hand the whole assembly up to the boat crew.
