Some situations underwater require as much light as you can get. The DS230 packs more flash capacitance to cut through the water and deliver sharper, more colorful, professional looking wide angle images. The DS230 has the power you need whether you're shooting in a pool studio or out in the open water.
Ike's theory was "smart housing, dumb strobe," resulting in the revolutionary concept of modular TTL intelligence. Simply connect the correct triggering device(s) and the DS230 will give fast and accurate output every time. This provides the ultimate versatility across camera systems, improves reliability, and insures against obsolescence as cameras with new TTL protocols are released on the market each year.
Entry-level strobes dump raw light from a standard, straight flashtube to maximize guide number (brightness). These strobes require light diffusers and filters to soften and warm light and smooth out the sharp edges and banding effects. Most add-on modifiers dramatically cut light output and reduce the effective power of the strobe.
Lighting needs for underwater photography differ greatly compared to surface photography, so an off-the-shelf flashtube and reflector won't do. We have spent decades revising and perfecting our circular xenon flashtube for a perfectly gradated beam pattern and warm color temperature. A 5000K color temperature balances with available light underwater to provide richer coloring and deeper blue water backgrounds when shooting wide angle. Models' skin tones will look more natural and reds and oranges will pop with more vibrant color.
For times when an even wider angle of coverage is desired, the optional Dome Diffuser # 4069.2 is available to extend the spread of the light with only a half-stop reduction of apparent brightness.
A custom formulated ABS-PC blend make the strobe fundamentally corrosion-proof and over 1/2 lb (237 g) lighter than aluminum-body strobes.
Life moves quickly underwater and you need to be able to react instantly when your lighting needs change. Shooters who use manual strobe exposure settings prefer our large, click-stop dial controls which provide intuitive, tactical feedback of exposure setting.
The robust dial controls are now even larger and taller for comfortable use with even the thickest gloves. A slide lock prevents the strobe from accidentally being turned on when not in use.
Your strobe is only as powerful as the batteries that drive it. Commercially available batteries do not have the low internal impedance required for truly fast recycle times. Even the best rechargeable AA batteries are sluggish in high-powered strobes and only get slower and weaker as their charge drains.
Our custom rechargeable cells power high frame rate firing from the first shot to the last. These premium quality industrial grade NiMH cells have been proven to out perform alkaline and lithium cells in real world underwater conditions, including the temperature fluctuations and storage conditions of the photographer diver. While 5 years is the average lifespan of a rechargeable pack, we routinely talk to shooters who are happily using 10-15 year old NiMH battery packs.
The battery pack attaches quickly and easily with a unique toggle lock that prevents accidental floods. You don't even need to lubricate the o-ring. The strobe front is compatible with older NiMH Battery Packs # 4066.5 or the DS230 Strobe Battery Pack # 40066BK.
