Hello i have been trying to deploy in deeper water where there is a current up to 1knt in the water column, near the bottom not an issue
By deeper water i mean 80 to 100m
I try anchoring the boat upcurrent and deploying the rov to descend as quickly as possible but the location that i end up is then variable and in addition the problem of having the tether being pulled by the current causes issues with moving around at depth.
Can any members share their experiences? Rope with a weight and gripper released at bottom? TMS would be great but then deployment etc, cost, weight. I toyed with the idea of a cage but issues of tether drag and entangelment.
