Supports high frame rate burst shooting when used with an Ikelite DS160, DS161, or DS230 Strobe and High Sensitivity Optical Converter #4405. Powered by two CR2032 lithium single-use or rechargeable batteries (not included), the transmitter has a built-in power save mode, lengthening battery life for at least a week of diving with average use. A spare set of batteries is recommended on trips. Compatible flash hotshoe is required for connection. 

Comes in handy for use with entry-level strobes with no electrical bulkhead. It can also be used with fiber optic cords to remove extra waterproof connections, or for disconnecting strobe cords underwater. Want to shoot split shots using natural light, without the weight of strobes, once you surface from a dive? Just disconnect your strobe arms, using the unique quick release mount, and hand the assembly to your dive boat’s crew.
