What type of rope for dive buoy?

[Ghetto Diver]

What type of rope/line are you guys using? and why?
I am putting together a buoy and am looking for suggestions.

I use three strand polypropylene because it is easier to splice. Knots in a line reduce the working and breaking loads. A simple overhand knot will reduce the load strength by about 50% or 60% while a splice will only reduce it by 10%. Three strand nylon line is stronger but is probably over kill for a buoy.

PS: If you need to put eye splices in the middle of the line poly is also the best way to go.

I use three strand polyprop for my flag because that's what it came with (and does a good job.) For my smb/finger spool I use cave line. But here is a link to a page you may find helpful. Classic Guideline Reels by Dive Rite - Dive Gear Express

You want polypropylene. It floats and remains more ridged so it wont foul up on you like nylon will.
