It's been one of my life dreams that I have never achieved.... But so close!
I wanted to buy one for the boat
but practicalities always got I the way.
Then a mate was given one and needed to get rid of it so gave it to me.
It takes up lots of space, salt
air gets everywhere etc. then you need to drag it by dinghy
in 37 bits of plastic, mount the tripod in the sand, exposé the hollow tube to salt
air and salt spray.... Then a cloud comes over.
So I gave it away, unused, to some people who loved it living on an island in a propper house.
My only thought would be to buy a cheap
one and replace as necessary.
