Has anyone else experienced problems with the Depth Hold autopilot where it just fires the downward thrusters at full power when the Depth Hold is engaged? It’s happened to me 3 times now, 2 times in a row last November and once again today. The weird thing is that is works exactly as expected excep…

Hi @Jake , It should be fixed in ArduSub 4.1.0, which is the latest stable version :slight_smile:

@williangalvani I tried the test build today and there was no sign of the problem, so far it’s looking like it’s fixed. Was this a known issue or was I the first person to mention it? It seems like other people should have experienced it before I did.

Hello, we’ve tested with 0.0.25 and ardusub-402-depth-hold-fix and versions but the vehicle still goes for a unwanted deep dive!

@schleitauche It’s the audio from the GoPro Hero 4 Silver mounted on the front (shown as the top left part of the video). Right now I sync the videos for the GoPro and the ROV stream with my phone camera flash as shown in the bottom picture at: Soap Lake, WA 1/29/2021 (Shallow Dive)
