This is a recent custom project completed by Spot X Underwater Vision. The main camera is a 4K/25fps low light IP camera. Dual 1500 lumen dimmable lights are mounted to the side of the tow sled. The live feed is viewed topside in full 4K, with data overlaid to the recorded video (depth, heading, date, time, GPS position).
The topside PC has IP65 rated connectors, a 1000 nit sunlight readable screen, and built in i5 high speed PC for video display/recording.
