Ikelite B3 ICS-5 Bulkhead with M16 Threads Overview Add the Ikelite ICS-5 bulkhead to your housing for the fastest and most reliable strobe triggering available for underwater use. This bulkhead supports TTL or manual strobe exposure, depending on the combination of camera system and accessories. TTL Strobe Exposure This bulkhead enables TTL (Thru-the-Lens) flash metering in a compatible system. TTL allows the camera to evaluate the scene and adjust the external flash output for each shot, ensuring precise exposure. TTL exposure is faster and often more accurate than manual flash settings, making it ideal for capturing fast-moving subjects. It simplifies macro photography and ensures proper exposure while you focus on framing. For wide-angle or close-focus wide-angle (CFWA) shots, set your camera to expose the background correctly and let TTL handle the foreground strobe intensity. TTL exposure requires: A compatible camera TTL hotshoe DS Link TTL Converter Current model Ikelite DS series strobes Ikelite-to-Ikelite single or dual sync cord Ikelite ICS-5 Bulkhead & Plug The Ikelite ICS-5 bulkhead is a robust and reliable alternative to the Nikonos V bulkhead. It features larger gold-plated contacts and a half-moon indexing design for easy plug orientation and secure attachment. ICS-5 fittings are widely recognised as one of the most reliable waterproof connections for electrical signal transmission, used in demanding industrial and commercial applications. Housing Compatibility Compatible with select housings by Nauticam and other manufacturers featuring a spare M16 threaded accessory port. Hotshoe compatibility depends on: Camera manufacturer Desired cable direction when viewed from behind the camera Use of a compatible TTL converter Installation Tip: After installing this bulkhead, perform a water pressure test and/or take an empty housing on a dive to your maximum depth before installing a camera. Regularly check the bulkhead’s tightness to the housing body. Sync Cord Compatibility This bulkhead is only recommended for use with newer sync cords featuring black hard anodized plug fittings with product numbers starting with "45." Older nickel-plated brass sync cord fittings may damage the threads and seize up. What’s Included Bulkhead with connector Waterproof bulkhead cap
