I dredge for gold in the nearshore waters of the Bering Sea near Nome, AK. We currently use a massive (24,000 pound) custom built ROV of our own design in 60 feet of water, my other boats use divers in shallower waters (15 to 30 feet). For both it would be useful to get side imaging scans while stationary, like the 360 does.
Will this unit do what I want? Are there any links to videos that show divers or moving underwater craft in the water at these depths? I'm in Nome and have very slow internet, but I can eventually get a youtube video to play. We've spend several tens of thousands of dollars on sonar over the past decade and I'm hesitant to drop $1500 for this add-on without being reasonably sure that it will work for what I want to see; but I'm not entirely sure exactly what I want to see. Knowing the orientation of the ROV to the mothership would be nice, also seeing the cut would be great, to know how fast the diver is working and if' they are getting "lost" and leaving material behind. I wish I could borrow one to test.
One dredge has a "999CI HD SI", the other has a "798C SI Combo".
Any suggestions or links?
