Brand new to this site. Some experience w/ scuba and freediving. I'm going to be heading to BUD/S (SEAL boot camp) and am looking for practical advice on getting accustomed to cold water. Basically I'm looking for any good books/articles/references that I could use to train up on before I go freeze my ass off at BUD/S. I want to make sure I don't drop myself from the program simply b/c I wasn't prepared enough for the cold water immersion that the SEALS are famous for.
