Nauticam Standard Clamp

I have Ikelite housing for my Nikon D7100 which is great mainly b/c it is transparent and durable. I researched the different arms for the lighting systems and bought the Nauticam Carbon Fiber Float Arms and the Nauticam Clamps which work great and are very easy to manipulate w/ my cold water dry gloves and 5mm neoprene gloves. I don't think I'll use anything else but Nauticam for my arm sets.
Optical Ocean Sales is superb. They provide reliable assistance via telephone, ordering online is streamlined, and delivery of my order occurs 2-3 days after placement at low cost. I intend on using Optical Ocean Sales as my #1 preference for online UW photography equipment orders.
