Pole cams for wary critters

I find myself frequently wishing I had a pole cam to give me added reach when working with skittish fish. I don't dive (not yet anyway!) and so am confined to snorkelling. The other day I was out trying to shoot American eels in an estuary here on Prince Edward Island and noticed that each time I would dive down (it's only about 6 ft but I'm trying to get "on their level" for a better POV) the fish would spook. This doesn't always happen, but frequently it does. I also notice this with trout in shallow rivers. Both are fine with the presence of the housing it seems, but move your head/body toward them and off they go.

Does anyone have photos/DIY directions (materials, mounting methods, etc.) for a pole cam that they've built that actually works? I'm shooting with a D7000 in an Ikelite housing (with Inon Z240 strobe). Looking to gather ideas.

I recall a thread on this idea some time ago. My lazy 30 second search didn't find it but maybe a little effort will reveal it.

I have made several postings here. As well you can see a few videos on my website that show my setups in action. I am using Seacam equipment. Main things you will have to figure out for your housing is how to attach the pole and how you will integrate remote control.
