Reply to: RE>>marker buoys
Jim,
The point of my post (perhaps poorly made) was that foam floats will crush at
depth. This was an "extreme exposure" for the pelican in question, and I
probably shouldn't have included it in my post without further details so I'll
copy this to techdiver.
A few years ago I was involved in raising a large chunk of brass from the Moody
wreck off LA harbor (150 fsw.) Our combined lift bags were not sufficient to
lift this thing so I marked it with a pelican float (on which I had extended the
line), intending to bring a line down from the boat on a subsequent dive. On
surfacing, we couldn't find the float. Current drag on the (extended) line had
pulled it down.
A week later we returned with a 2000 lb bag, and raised the brass with the
pelican line still attached. I retreived the line and found the float still
attached, but a week at almost 6 atm had crushed it badly. (looked about like
an over-cooked chicken wing) I didn't consider this Pelican's problem, so there
was no call for a warranty claim.
I like and regularly use Pelican products, including the float. In this case, I
obviously exceeded its design parameters. But for all around use, I prefer the
lift bag/ascent line rig.
My favorite float of all time is one with no utility whatsoever. A yellow
plastic piece of over-engineering with a latching line reel triggered by a
non-floating arm that was supposed to stop the deployment of line when it
reached the surface. I bought one in the 60's `cause the box had Mike Nelson's
face on it. Crazy George Krasle in Atlanta still had dozens of these things a
couple of years ago, I bought two for $7.00 each. They're classic.
And now back to your regularly scheduled programming...

Gerry:
I saw your post regarding the Pelican float. Most of your criticisms were
dead on point, but I am intrigued by your observation about the Pelican
float crushing at depth. I routinely wear one to depths of 120' and have
never experienced any crushing or deformation.
At what depths has this occurred for you? Could this be a manufacturing
problem in one batch or do you think it is a design problem?
Pelican has the best warranty in the business - if anything goes wrong,
ever, send it back for repair or replacement. No questions asked.
