I am in the market for an underwater camera and seeing as I have never owned one before I had a few questions. I will be using it in pretty clear water 90% of the time and down to depths of 40 feet or so. I am leaning toward an Aqua Vu but with so many models and salesmen who don't really know much about the product I am a little confused.

Is the Spectral Response illumination better than the Infra Red?

Are the older style of Aqua Vu's with the smaller screens worth the extra money over the newer Scout XL style with the soft case and big monitors?

Any advice would be appreciated, a lot of guys up here use them, they just don't say which models are worth it and which ones don't cut it at all.

Thanks!!
