Viking,

I bought an Aqua-vu a couple of years ago for pond observation. Tried it out once and immediately boxed it up and sent it back for refund.

I had two problems; 1) the infrared light and temp sensor didn't work and 2) it was not "steerable"

As a result, it couldn't do the task I wanted it for...fish observation.

Maybe things have improved since my experience....if so, I'd like to hear about it.
