Hi,  
I work in the ports and recover the moorings, chains lost at the bottom … I have a BR2heavy, with the gripper BR.  
To catch at the bottom I have to tilt the ROV and even at 25% power I lift too much sediment to be able to maneuver.  
Can I set the power to +/- 10% for the maneuver and increase to ascend ?  
Mount the gripper tilt to keep the ROV flat with the camera at the lowest ?  
Have you already tested ?  
Many thanks

See JS\_GAIN\_MIN and JS\_THR\_GAIN [parameters](http://www.ardusub.com/operators-manual/parameters.html).

> Hi I was wondering if there was anyway to lower the gain of the ROV further down past 25%. When you are doing very delicate operations the 25% is still too much input. Heinz

> A few depth hold question. When i push the depth hold button on the surface the ROV immediately dives to about 0.5m is this normal… Can the speed of dive and surface be changed my Blue ROV When I pull back on the stick even a small amount the ROV dives quickly. Thanks David Ardis
