I originally published these instructions a while ago on my blog, but I figured that I will be more useful here :) 

Following a friend’s request I decided to explain how to build a fiber snoot for underwater use. On this post I will explain how to make a snoot that fits an Ikelite DS-50 substrobe. 

I first saw the results of using a snoot for underwater macro photography a few years ago, when I met one of the most talented and creative underwater photographers I know – Keri Wilk. We participated in the annual Epson Red Sea competition – an underwater shootout that takes place in Eilat (Israel). Keri took some amazing photos using his snoots, and he later explained his technique in a blog post on DivePhotoGuide.

I wanted to experiment with snoots and build my own, but instead of using plastic tubes I decided to use fiber optic cables. With fibers, I can place the strobe anywhere and then just use the flexible Loc-Line “arms” to point the lights anywhere I want.

Step 1: Materials

What you will need:
  • Ikelite DS-50 / DS-51
  • Barrel Plugs/ round ribbed tubing plug to use as an adapter for the snoot. I do not know the technical name for this part, but I found a nice white plug in the plumbing department in Home Depot. The one I used has a 99 mm diameter, which fits nicely on the DS-50. You can see it here and here.
  • Loc-Line parts (for snoot “arms”)
    • 27cm of 1/2″ segments, 1/2″ NPT Connector, 1/4″ Nozzle. Check it out on this page.
    • 41cm of 1/4″ segment, 1/4″ NPT Connector, 1/8″ Nozzle. Check it out on this page.
  • Solid core jacketed fiber optic cables. I ordered mine from Fiber Optic Products:
    • 47cm of 4mm cable (EGS4B)
    • 35 cm of 7mm cable (EGS7B)
  • 23cm of thick (5mm) rubber band, 1.8cm wide. We will  use this piece as a spacer between the strobe and the snoot adapter
  • Optional – metal/plastic nut to secure the NPT connectors. You might need to get creative here.
  • Velco straps (optional)
  • A small saw
  • Drill
  • A conical drill bit that can make 12mm and 20mm holes
Very nice work. I'm thinking about applying some of your ideas to making a flexible fibre optic illuminator for my microscope.
Nice man. I love diving, but unfortunately I can't afford it. Nice job.
thanks :)
