Insurance coverage?  The equipment would need dissassembly and
cleaning, and you can bet on the almost certainty that some components
will be damaged.  Unfortunately, turning it on while there is any trace
of water inside tends to cause further damage to any bits that might

I would donate it to someone who loves tinkering, and let them have a
go at pulling it all apart and cleaning it.  But unless that bucket
contained pure distilled water and you got them out instantly and dried
them perfectly.. I think you now own two pieces of toast..

However remove the batteries. Remove the memory card. Open any doors, place
them in a warm dry place and let them sit for a few days. Putting a fan
blowing on them would not hurt.

It you are lucky, they may dry out enough to work again.
