I took my newly built OpenROV to Lake Merritt this past weekend. The visibility was good, and I managed to spot a stingray with the ROV as shown in the video below. It looks like ray sightings in the lake are uncommon but not unheard of as one was spotted in April of last year. I’ve taken the ROV on a couple of dives with no visibility and nothing of interest, but this was the first time I’ve been able to see anything.
Here are highlights of the whole dive.
