I once lost a CQR anchor
in a storm with chain and rode
. My second anchor held, but the CQR
chafed through during the night.
I went looking for it in the dingy with a grapnel hook for hours. No luck. I finally gave up hope of ever finding it. As I raised my remaining anchor to depart, what came up with it but my CQR! LOL.
I was extremely happy that I did not have to pay for a new one.
Just thought I would share....
In 9' of water
, if the water
is clear enough, I would just use a piece of glass on the water. We made them as kids
, 4 sides like a pyramid and the glass on the bottom. Just silicone everything together let it dry and you are ready to go.
There are also very cheap
underwater cams on Ebay. I have one and like it a lot for viewing fish
and so on.
Sonar I agree will most likely be no help.
Under water metal detectors might, but in a marina there will probably be a lot of stuff down there. Lot's of false hits. And you still need to dive to see what the hit was. Really only useful if it is buried in silt or sand.
