We fish offshore in the Gulf of Mexico at depths up to 500m trying to locate bottom structure composition but it looks like 100m depth seems to be where the technology is currently at for DIY or the average non-commercial consumer (though I did see a post on here where someone took the OpenROV battery capsule down to 200m and was going to test at 300m).
Where is a good resource to research commercial or high-end consumer/DIY models that includes pricing? I’m wagering most are out of our price range but would like to know what is out there for the various depths and prices.
Is 300m the technological max for a tether for OpenROV meaning the signal breaks down after that?
Is there any way to triangulate the ROV’s position underwater relative to the boat in order to get a semi-accurate GPS reading of the ROV? With neutral bouyancy I imagine we have to drive down to the bottom rather than dropping like a weight so we’re likely to get more off track from the currents.
Is visibility at these depths mostly up to the current sea conditions and bottom composition as to whether the video is viewable (assuming we use the external light cube)?
