David, It is basically a divers flag and float that I rigged up to a
retractable dog leash or clothes line. The clothes line is longer (30
feet) so I have switched to it. The divers flag sits in a holder and as I
submerge the float keeps the flag on the surface until it reaches the end of
its line. If I submerge to 45’ or so the foam float compresses
to the point where the retractor starts pulling it back to the sub. Because
there is no slack in the line I have not sucked the line into the prop yet but
it is something I remain cognitive of and if the line is perfectly vertical the
flag will drop right into its holder. Now the tricky part is if I am
surfacing where there is possible boat traffic I try to ascend very slowly so
the flag can redeploy as it regains buoyancy, unfortunately it also has the
effect of dragging the sub up with it so I need to adjust ballast or apply
downward thrust as the flag ascends. I would not try to use it where I
was going under things like docks or submerged trees because it would definitely
be a hazard. I have photos posted here: http://www.psubs.org/projects/1249704587/retractablediversflag/ Kyle From:
