FeaturesMultiple features condensed into a compact designCircular beam angle of 100°x100° and guide number of up to 20. The YS-01 is a new compact-type slave strobe that can be used for all applications from wide-angle to macro photography.You can switch between DS-TTL (Digital Slave TTL) and a ten-level manual control function, to enable fine adjustment of the light level according to the photographer's intentions. You can also set up a lighting system that uses two strobes in DS-TTL mode. Power comes from four AA batteries for a powerful and long-lasting strobe. You can enjoy taking pictures all day long without having to recharge the batteries. The recycle time takes about two seconds with nickel-metal hydride batteries (2700 mAh) for stress-free continuous shooting. The YS-01 is furnished with a high-luminance white LED target light (1W) indicating the optical axis of the strobe attached to its front face that is effective for night diving.You can fully exercise your creativity with the YS-01, which can be used as a primary strobe or secondary strobe in a wide range of applications, from compact digital cameras to digital SLR cameras.Sea & Sea YS-01 Underwater Strobe/Flash Lighting Package with Sea Arm VII CompactPart SS-70033This Strobe set is suitable for ALL Point and Shot UW housings made by any manufacturer1 x YS-01 UW Strobe/Flash Head (Part SS-03112)1 x Sea & Sea Arm VII Compact Set (part SS-22124)1 x Strobe Mask Set (part SS-50109)1 x Fiber Optic Cable (part SS-50107)1 x Diffuser1 x Silicon Grease1 x O-Ring Installed YS-01 UW Strobe/Flash Head (Part SS-03112) The Sea & Sea YS-01 is a compact slave strobe that can be used for wide-angle or macro photography above and under that water.

Dive into underwater photography with this compact yet sophisticated system!
TTL or "Through-The-Lens" flash metering means the strobe interprets information from the camera to control flash duration and properly expose an image. TTL may be accomplished directly through electrical signals from the camera, or indirectly through watching the behavior of the camera's built-in flash.
Circuitry built into this housing allows the camera to communicate directly with compatible underwater strobes (see Strobe Compatibility section below). When connected via this circuitry, the camera learns that an external flash is attached and is able to more accurately adjust exposure by knowing this. The camera's flash will not fire, eliminating the shutter lag associated with waiting for the camera's flash to recycle.
The Ikelite-style electrical bulkhead is widely recognized as the most reliable waterproof strobe sync connection available. In order to communicate with the camera, compatible Ikelite DS strobes must be connected to the housing's electrical bulkhead using a single or dual TTL sync cord.
Non-Ikelite strobes may be connected to this bulkhead using a compatible sync cord, however the housing's circuitry will not receive power and the strobes will operate in manual exposure modes only.
Whether in TTL or manual exposure, use of an electrical sync cord eliminates the issues of signal interference, inconsistent exposure due to weak fiber optic transmission, and false triggering caused by light rays bouncing off the water's surface or your buddy's flash going off. Sync cords are comparably priced to fiber optic cords and are equally durable.
Durable polycarbonate and acrylic construction provides a unique view of the camera to ensure correct waterproof installation and confidence underwater. Simply close the two stainless steel locking lid snaps, and see the o-ring form a solid black, watertight seal. Large, ergonomic controls provide access to all important camera functions including front and rear dials. An included tray with soft-grip handle provides comfortable handling underwater and our signature quick release attachment system for lighting accessories.
Ikelite products are designed, built and tested in the USA. We use locally sourced, top-grade materials. Our housings are built by hand and individually tested for fit, function and waterproof integrity. We back our products with over 50 years of experience and service within the dive industry.
The housing port is designed to accept color filter, wide angle, and macro options for 3.9-inch diameter ports. Light is absorbed very quickly as it passes through water. A subject will look darker, less colorful and somewhat grainy when viewed through even a few feet of water. The addition of a compatible wide angle accessory expands the camera's field of view underwater, providing the opportunity to get as close as possible to the subject and reduce the amount of water light passes through. The results speak for themselves - photos with the best color, exposure and clarity possible.
For SEA&SEA or Nauticam housings with internal fiber-optic flash triggering devices, we recommend the Fiber Optic Converter, see below.
Trigger your Ikelite DS-series strobe off any camera or strobe flash. The Optical Slave Converter simply attaches to the strobe's electrical bulkhead in place of a sync cord connector. The enlarged slave window provides approximately 90 degrees field of view for remote triggering. Recommended if wireless slave triggering is your primary application.
The Optical Slave Converter can be extended using the optional 3-foot Extension Cord for creative backlighting in wrecks, caves, and pool studio set-ups. It can also be used above water for studio photography work.
The Optical Slave Converter supports manual exposure modes as set on the attached DS strobe. TTL exposure mode is not supported.
An individual Optical Slave Converter is needed for each strobe. Use of multiple strobes requires one Optical Slave Converter per strobe. The Optical Slave Converter supports DS50, DS51, DS125, DS160 and DS161 strobes.
The included fiber optic port threads onto the front of the Remote Optical Slave Converter for the attachment of and triggering via a fiber optic cord. This Converter is sensitive enough to fire the strobe via fiber optic cable with most camera flashes. It is not recommended for use with LED fiber optic triggers by Nauticam, SEA&SEA, and other manufacturers.
The Optical Slave Converter automatically configures itself for compatibility with both pre-flash and non pre-flash camera modes. No setting of small switches or confusion over number of pre-flashes. Simply turn on your strobe and take one picture to configure.
