I was wondering if the ROV community could advise me about whether portable ROV's exist for exploring deep lakes. The one that I am examining specifically is located in Dragon's Breath Cave in Namibia. This is the world's largest underground lake, 5 acres in area. 100 feet below the surface. The depth of the lake is beyond 300 feet, and its bottom has not been surveyed. access is through a small hole in the ceiling. you can get inflatables down there, but do small portable ROV's exist?
thanks to anyone for information. cheers, tco
