Inon Knob tests

My last post was about the cold water knobs for my Inon strobes that I got from Jonas Odell. I managed to get them wet in Capernwray on Friday with David Kneale and David Elliot. The sturgeon were most obliging-and Dave Elliot gets Strugeon Wrangler supremo points for actually de-tangling the sturgeons barbels! The viz was superb, although it was a gloomy day. I was using my Nikkor 105mm VR that I mentioned in my earlier post, together with a Fisheye focus light. The water clarity is so good that you can use the 105 as a short telephoto:
    
The backscatter is from the strobe position-I think they were a tad too close.Anyway, water temp was 4 degrees, and my right dry glove seems to be seeping, so my hands were pretty cold. In the past, I have really struggled to adjust my strobe's power output when cold due to the size of the knobs on the Inon strobes (see my previous posts), but with the extenders that I got from Jonas, even at the end of a 45 minute dive, was able to easily adjust them-result! Here are some more pictures from the dive:
  
Thanks to David and Dave-looking forward to the next one!
