These are home-brewed hillbilly engineered Ikelightener's. (Not my naming- It belongs to Gene Gray in Montona)
Anyway, I bought an old ScubaPro 3mm wetsuit on Ebay for $20. and proceeded to cut it up to make the "wetsuits" for the strobes. They work really well to protect them from rocks, etc.
Anyway, they didn't make the whole ungainly DSLR with dual DS-120's managable so I cut up some "water noodles" from Target. ($3.00) I sliced them lengthwise and put them over my UltraLIght arms, securing them with zip ties. These worked really well but were Fugly and compressed at depth. When compressed they worked their way out of the zip ties and were a hassle.
THEN, my buddy Gene Gray sent me his Ikelighteners. These soap bar sized floats fit under the Strobe Wet Suits and solved the problem of a heavy DSLR system.
Methinks the entire D200 housing, camera, and Dual DS-120 system was 2-4 pounds negative. See the pics attached.
Needless to say, the strobe wet suits turned a few heads, but doggone it, the hillbilly engineering worked!
Tell me WetPixel readers, what do you think the market would be for such a system with wet suits and float? How much would y'all invest for a professional looking version of this system?
