What kind of experience do you have with salt water and your equipment? Salt is very aggressive and could ruin a lot of electronic equipment. Recordings on the beach, on the sea, the air is full with salty dust which allegedly could also find a way through good Rycote-Windshields. ?? If the salt is on/in electronic components it slowly makes long-term demages.
Some years ago, I went to iceland and made some records from the sea. Friends alert me about the salt and made me afraid. I was very careful, nothing happend until now, everything's still runs fine.
On Tim Prebbles website http://hissandaroar.com/amb001-blow-holes/ we can see a lot of great pics from his recordings at the coast.
@Tim: Did you have any problems with your equipment because of the salt? On some pics we can see that your windshield is quite wet. No Problem with the salt?
How is it with someone who lives close to the sea?
