Not much to say about the Aquatica D200 as Alex put it, its still Vapour-ware
(good one Alex), but design element of the D2x version will follow up on the D200 housing. as far as the Optical Acrylic versus Glass, as an industry member i'm pretty, make that very bias to our products and that's the way it should be, nonetheless after countless post, many a healthy discussion and even some spicy $%&&$%#@* chosen word on this subject from this community, the cleavage remain and honestly you should rely on your perception and not opinions, so far I have yet to see conclusive scientific side by side data that would confirm Acrylic optic are better than glass and vice versa.
Factors to vector in a system are pretty down to earth.
Cost, weight AND size with all accessories (ports, extension rings, gears etc.) ease of handling, that's the catchy one since it's seldom that you will encounter all canditates and actually have a side by side handling opportunity, best place for that is a show like Beneath the sea where all the hardware is present. Again as industry members, we all want to strut our stuff so yeah ask me and you'l get the same answer as Ike will give you: buy our stuff it's the greatest
and we are right. in the end my grain of sand is : buy what you need, not an opinion, not somebody else wish list, by our's or there's but get one and get in the water.
Cheers
