Plug to use a regular tosslink cable to shoot strobes underwater.
Regular cables are around 40USD the pair.
With 4 of this plugs and 1 3 feet tosslink standard cable you can make two working triggers for the strobes. just 2 or 3USD
There are two models.
One for a 3,5mm wide cable. You cut the tosslink plug and insert the cable in the printed plug. One for the housing and one for the strobe. Easy.
The other model is for a 2mm fiber optic cable. If you peel carefully the 3,5mm fiberoptic cable you can get the "inside" cable. The same size of the standard trigger cables.
It has two holes so you can "double" the signal with two cables. or use only one plug in the housing with two cables.
You won´t have a flexible retractil "telephone type" cable. but works perfectly.
The sizes are a bit tight to assure it will fit strongly. You can always reduce it.
