Based on recommendations in a previous question, i'm now looking at purchasing a couple of powerful flashes.
As far as i understand, almost all flash units are not waterproof at all. Since i take my gear into fairly hostile environments. A completely sealed unit would be ideal.
In light of recent experiences with cameras and water, i'd like to know if there are any waterproof (not diving equipment) camera flashes i can use with a Canon 5D?
Hope you can help!
