Can you see it??? Buy a cheap mask and dive in, 13.5' should be easy to get to. I would think it would be more cost effective to buy a new rod and reel than have a scuba diver come up and rescue it.
$15.00(?) tank
depending on how cold the water is...75deg or up may not need 7 mil
hood $5 Maybe, again depends on water temp
weights $5
trip to Lave Gevena (Gas) $10-15
