I have the Aqua-Vu SC-100. Only had it a few days. Before I had the Aqua-Vu DT, that's the one that shows depth and camera direction. I tried two of them from Cabela's, both had problems maintaining the correct dept reading... after using for a few minutes they would add 46 feet to the depth reading. I gave up and decided I didn't need one with depth so I returned them and ordered the SC-100. The underwater camera is pretty neat, lets you know what's really down there. It showed me that Fish Symbols on my sonar are a joke. Some places the sonar showed fish.. there were none.. other places it showed no fish and there was fish on the camera. I had the other two cameras back when it was cooler, at brush piles and my dock I was seeing a lot of fish... tried the other day and hardly any fish. The SC-100 works in sunlight without having to use a sun shield. The monitor uses an LCD and not a CRT. Also the reel is pretty neat for storing the cable. The monitor is a lot more compact than than the DT... both uses the same camera. BTW fish are not afraid of the camera for it looks like a fish. The first time I charged the battery it swelled up like it was going to burst.. called Aqua-Vu.. they are sending me a new battery If your buying, I would recommend to buy where you can return if you don't like it.
