We have had some current <1.5 knots and it moves quite well. In water shallower than 150ft a single line has worked well so far. We found a tug earlier this summer in 90ft of water. We will be using the unit on Monday and I'll post here some pictures.
For deeper stuff we have only done one deep dive so far just to shake the unit down. We had a two point mooring system off the bow (port and starboard Danforth anchors) with 500ft of line each on a wreck that's 236' to the mud. I drove the unit straight down to the bottom from the swim platform and used the compass to navigate to within visual range. Then we turned around because we didn't have a diver to retrieve it if we lost it and don't have a developed skill set yet for deep stuff. By next year we are hoping to be good enough to replace some diver operations.

VERY useful. Thanks. It turns out that their factory is less than an hour drive from my house. I'm going to ping them and see if I can setup a visit and try out the technology in a real-world situation here in SoCal.
Thanks again,
