I wanted the MAV when they were first introduced but could not justify the price but I found a place selling all of their MarCum and Aqua Vu half off, and they had the MAV marked down from $2499.00 to $899 so I had to do it. here is a link for anyone looking for a good deal on underwater cameras Click here The MAV does not work with the Aqua Vu DVR so I will need to figure out a different way to record thought the RCA Video out jack how do you do it with your 825C?
