RetraFlash PRO X Underwater Strobe

The "Underwater Flash for the Highest Demands" Project Performance that lends itself to wide-angle underwater photography, even backlit, or the most technically demanding macros, without the need to increase the ISO sensitivity of your digital cameras. A high-quality light without compromise, with wide, even coverage and a slightly warm colour temperature. Modern, highly efficient electronics, versatile, with synchro and fibre optic cable connections, supported by on-board TTL digital protocols. A flash unit that is easy to use, with ergonomic controls and easy-to-read settings. A quality product, extremely robust and reliable. Electronics Power supply, digital control and advanced functions, high reliability. Maximum energy 157 Ws (J) e-TTL Canon, s-TTL fibre optic, on-board digital protocols Dual CPU for TTL protocols and power switching At the heart of these advanced electronics is a powerful CPU that manages the entire underwater flash with sophisticated digital communication software between the camera and the flash, perfectly interfaced with Nikon's i-TTL protocols. This mode allows us to achieve a very accurate exposure of the flash light without the aid or interposition of a converter. Additional functions such as focus light and synchronisation to the second curtain are also supported. In addition to the protocols managed with a sync cable, s-TTL mode is also supported for signal transmission via fibre optics. A second CPU manages the circuits to optimise performance in every situation and maximise battery life and safety. Selected components with strict quality parameters and intelligent management of all operating functions of the strobe ensure very high reliability. Mechanics A realisation without compromise, robustness, precision and workmanship at the highest level. High-quality, hard-anodised, anti-corodal aluminium flash body. Stainless steel control shafts with double-sealing O-ring. Extremely stable construction, maximum operating depth 200 m The body consists of a solid block of anti-corodal aluminium alloy machined with state-of-the-art multi-axis CNC machining centres. The aluminium is surface treated and protected by a hard anodic oxidation with a nanotech quartz coating that makes the surface hydrophobic. All control shafts are made of stainless steel with double-sealing O-ring. The various engineering polymers selected for the moulding are extremely robust and ideal for use in water. The robustness of the design allows the underwater flash to be used in all technical dives, hyperbaric tests are carried out at pressures equivalent to a depth of 200 metres. Operating elements Ergonomics in the foreground. Basic, large, easy to use. Large format ergonomic controls, really easy to use Simple and rational layout, large manoeuvring area Easy to read, wide control display To achieve these results, the engineers designed the layout of the controls to simplify and streamline their functionality: no buttons, no switches, just two large lever selectors, a multifunction rotary switch and a large, easy-to-read control panel. This simplification, combined with the elimination of connection sockets and associated cables near the control, has made it possible to have a large operating area that allows a wide view of the selected settings and enables easy operation even with gloves on. The side lever selector switches, the rotary knob, the open-close selector switch for the battery compartment cover have been developed according to strict ergonomic criteria to achieve optimum operating comfort and grip safety. The controls for their configuration are insensitive to hydrostatic pressure. You will operate them with the same effort at any depth.   Functionality Easy to use, logical and intuitive operation, good clarity. Shooting modes: Nikon i-TTL, Canon E-TTL, s-TTL, film TTL, manual Energy control - manual mode - ½ aperture steps in the range of - 6 Exposure compensation - TTL mode - ? Aperture steps over a range of +/- 2 The red main switch on the left controls the focus lamp (in the two available powers) and the TTL flash modes, via sync cable and via fibre optic cable connection. The protocol selection (Nikon i-TTL, Canon E-TTL, optical s-TTL) is automatic. The control lamps ??-PL-TTL indicate flash readiness, the switching on of the control lamp or the selection of the TTL mode. The black INPUT lever selector switch on the right-hand side allows us to choose the input and connection mode we want: Sync cable jack, fibre optic cable jack, optical receiver on reflector for slave mode. The indicator lights show the selected SYN-OPT-SLV input.  Power control is delegated to the central rotary switch, which operates an encoder. In manual mode, the setting is ½ aperture steps over a range of - 6, while when TTL mode is selected, the exposure compensation control function is assigned to ? F-stops over a range of +/- 2. The selected setting for power or exposure compensation is clearly visible in the centre area of the large display. Simultaneous one-hand operation of the left and right lever selector switches the unit on and off. Power supply High efficiency and autonomy, safety without risk. Replaceable NiMH battery pack High battery capacity, more than 250 flashes at full power Fast, CPU-controlled charging times of 0.1 to 1.8 seconds No restriction for air transport in the cabin. Power is supplied by a replaceable NiMH battery pack made with Panasonic's best professional high energy cells. More than 250 flashes at full power are guaranteed by charging times of 0.1 to 1.8 seconds electronically controlled by the CPU. The special table charger enables fast charging in less than two hours. The remaining charge check is visible on the display every time the flash is switched on and off. The manufacturers have paid the utmost attention to safety by providing the battery pack with short-circuit protection, making the battery compartment waterproof and equipping the compartment's sealing cap with a safety valve. Safe to transport and use, practical and quick to replace, with a second unit you will always have an energy reserve for all your needs in a matter of moments.

NEW, YS-D3 MKII MODEL Sea&Sea has now updated its flagship YS-D3 strobe to the YS-D3MKII. The new updates enhance TTL shooting and third-party optical converter compatibility while still retaining all the great features, such as a 33 Guide Number, wide Beam Angle and broad flash distribution of the original D3 The new MKII model will be a “running change” update, that is, the product number (#03123), will remain the same. Features of the YS-D3MKII model Newly developed software enables compatibility with existing and previous Sea&Sea optical converters. TTL shooting with the YS-D3MKII can now be enjoyed using the YS-D2 position on the S&S optical converter. A newly designed circuit improves the accuracy of TTL light intensity with compact cameras and also provides greater compatibility with third-party Optical TTL converters. The design of the light intensity adjustment dial and mode switch has been revised for better useability in all diving environments.  The difference can be easily recognized from the outside by the MKII label on the side of the unit and the new control knobs on the rear. High Performance U/W-Strobe Newly designed circuitry and light-emitting unit produces powerful guide number of 33. In addition, a high precision aspherical optical troidal lens has been fitted over the two flash tubes to disperse an even light from the center to the edge. The strobe`s beam angle will increase to 110°by attaching the standard accessories Diffuser. When the optional Dome diffuser is attached, beam angle will increase to as wide as 150(TBD) In order to avoid misunderstanding, the YS-D3 guide number (GN) and the beam angle are based on measurements taken on land (not underwater)  Some competitors will often state a GN measured on land and the beam angle in water, for example a GN 33 and beam angle of 110 degrees. However, this GN 33 value is based on a beam angle of 60~70 degrees. The beam angle may be expanded in water by a dome effect, however the GN in water is significantly lower than the value measured on land.  Note: A land-based strobe that uses the same four AA batteries as the YS-D3 may provide a notation that the GN is 60, but these measurements are taken under the condition that the focal length is equivalent to 200 mm (= beam angle 12 °). When the beam angle becomes narrower, the brightness of the illuminated area increases due to the light-collecting effect. Aspherical optical troidal lens Superior consecutive firing capability to capture those critical moments. The YS-D3 utilizes larger capacity condensers compared with those used on competing strobes. In addition, the D3 is also equipped with a newly designed charging circuit. As a result, the YS-D3 will fire at GN16 continuously without any interval time. Even when the strobe is fired at GN22, the strobe will fire again within a mere 0.8 seconds.  When the YS-D3 is fired at Guide Number over 22, a two-stage ready-to-fire signals will be issued. For instance, after the strobe fires at full power of GN33, the strobe will inform you both visually and audibly when the condenser is charged to fire at GN22. Then, when the condenser is charged enough to fire at GN33, another different signal will be issued. This design allows you to release more shutters in scenes where you want to shoot as many pictures as possible, maximizing shooting intervals between scenes Target light with increased power incorporating a uniquely designed aluminum heat diffuser, the target light is now powerful enough to be used as a dive light.?About 4 times brighter than YS-D2? Various accessories available for all underwater imaging experiences Dome diffuser (optional accessory) Increases beam angle to 150°×170° Essential accessory when fisheye lens is used, or soft light is required. + Guide number will drop to -1.5EV when it is fitted. Snoot (optional accessory) A strobe adaptor which narrows the beam angle to be directed at a target point. Diameter of the opening 25mm. Designed with internal prism which aligns target light`s light axis and strobe`s light axis to the center. Flash prism (optional accessory) Optical guiding device to fire the strobe when a fiber-optic cable is not used. This device is for manual use only. The device is effective if multiple strobes are used in a fixed position.  However, the flash may not fire depending on the position of where multiple flashes are occurring in relation to that of the master flash.  Excellent visibility Backlight panel that is effective when shooting in dark environments The indicator color on the back of the YS-D3 changes each time the position of the mode switch is changed. Blue (in DS-TTLII mode), light blue (in slave TTL mode), orange (in manual mode with pre-flash), and green (in manual mode without pre-flash) The positioning of the operation system is obvious during night diving. * The color in DS-TTLII mode has been changed from the YS-D2 to match the color with the optical converter. In DS-TTLII mode In manual pre-flash mode   In manual non pre-flash mode Connection method with arm that can be selected according to preference YS-D3 comes with a straight type ball base. Optional YS base and new Diagonal ball base can be installed depending on the application. YS base (common to YS-D1 / D2 / D3) Traditional YS base. Easy vertical swing. Diagonal ball base (only for YS-D3) A ball base inclined at 35 ° compared to the straight type. This makes it easier to lower the strobe backwards, making it suitable for shooting when using a dome port. Also, when a Synchro Cord N is installed, interference between the cord and the ball clamp is minimized.
