How to deploy Surface Marker Buoys.

Talking of line, it should be the depth of the dive plus half, so a 30m dive you should have 45metres of line.

For deep Tec dives agree, but recreational divers buying standard lengthlines and they are 15 or 30 m on a simple spool. For longer line ther’s a reel needed then. Can’t imagine a regular diver diving with a reel:)
