One of the guys on NCBF is a CatchCam rep, I believe. He had offered to let me demo one once he got his hands on an available unit. I seem to recall the CatchCam was getting the nod over the AquaVu on similar queries on NCBF's Forum. I don't know if it's smaller/lighter, but I think the CatchCam camera supposedly works better than the standard AquaVu one (I think AquaVu has an 'enhanced' (infra-red?) camera that you can pay extra for, where CatchCam offers a better one as standard).
Sorry, this is all hearsay, second-hand info, but I made a similar query months ago on the NCBF board, and that's how I recall the way the feedback came in. I came away figuring I'd go with the CatchCam.
Hope that helps! Maybe if you post a query on the NCBF Forum, you can find that rep for a demo run.
Let us know what you come up with!
