The housing

This housing features our robust Dry Lock (DL) port system. "Dry Lock" refers to the placement of the o-ring on the outside of the port mount. DL ports are the lightest on the market, yet robust and capable of standing up to rough surf. Attachment is quick and secure. A system of extensions can accommodate a huge variety of lenses with ease.
Most popular zoom lenses and select lens focus rings can be engaged using simple gearing that puts adjustment right at your fingertips. A large, soft-touch knob on the side of the housing makes fine tuned adjustments a breeze.

Vacuum System
A vacuum valve is installed standard on the side of the housing. The vacuum valve is designed to be low profile to avoid interference with controls. The optional Vacuum Pump with Gauge #IK47011 allows you to draw a vacuum on the housing to check for leaks prior to entering the water.
Drawing a vacuum on the system also provides extra security at the surface of the water, especially important when using the housing in rough surf.

TTL 
This housings supports your choice of shooting with manual strobe exposure or adding a TTL converter depending on your application. The flash bulkhead is located on the top of the case to alleviate strain on the sync cord. You can enjoy the fastest and most accurate TTL exposure on the market by adding the DL2 DS Link Sony TTL Converter Ikelite ST1 Hotshoe Kit #IK46042 and a compatible Ikelite DS strobe. Exposure compensation can be used added or subtracted in the camera.

Strobes
Any Ikelite DS strobe may be used in manual exposure modes by attaching one or two with a compatible electrical sync cord. Current model DS strobes may be used in TTL exposure mode by adding the optional DL2 DS Link TTL Converter and an electrical sync cord.

Non-Ikelite Strobe Compatibility
SEA&SEA & INON strobes with an electrical connection can be triggered in manual exposure modes using an electrical sync cord. Strobes without an electrical sync cord connection cannot be attached to this system unless slaved off of a hard-wired strobe.
