Got this covered...



Restriction, I think not. Sweet LED light too.

Great idea Mat!!!

The ROV I mentioned does not drag the cable behind it, it unwinds from the ROV. The ROV is connected to a base station which has a larger cabel which goes to the surface. The "exploratory pod" of the ROV carries 3000' of cable. I do not know if this ROV would be able to move against a significant current (I doubt it), and of the 2 types I hav seen, the smallest is about 1.5 cubic feet in volume, with 12" in the smallest dimension. So the main concerns with using an ROV in this case would be.
1. None of the ROV models of this type can fit past a 4" gap
2. Difficulty moving against flow
3. No reason to look in an area that a human skull cannot pass through.

Just how big is a spool of 3000 ft? a spool of 1000' of cat 6e cable is about 14" in diameter, with a 3" diameter core.

Here's a bunch of ROV cameras, but none of the "ultra-thin kevlar cables" are greater than 400m.

Im really starting to feel sorry for those dvers who have to assist on this. Sounds like a lot of work!! I like Mats sub idea

Mine only cost $15

Well you have to consider that you'd likely use armored (kevlar) wrapped fiber spools since it's being pulled on and run over abbrassive surfaces.

our 100 meter armored fiber spools are easily 18" to 20" in diameter with a 8" core I'd guess.

they are also heavy. Any ROV that can spool out 3000ft of it will be too huge to fit through a crack purely based on it'd have to be big to "float that spool" and be able to hold it in a mount.

Hilarious Mat!

that might be fun just to mess with folks in the basin at Vortex. would be really cool if you could waterproof the control unit and "take it with you" on a dive.

I'm jealous! But "mine's" bigger . . . :blinking:

So, taking a SWAG, what would you say the weight per foot would be? and What is the cable diameter?


Just my $.02 SWAG -- It will have to be reeled out from the surface . . .
