Hi all, I am a POHM living in Melbourne Australia. I have had my SSI open water for a bout a year now and have managed to log a hole 9 dives. but after a visit to Antarctica this March I have been inspired to return in feb 2010 to dive there. I have been informed that i need to have 100 logged dives for this trip and at least 20 of which need to be in the dry suit that i will be diving in. currently I only own snorkel gear and so i have a large finacial investment to make in the near future. any advice would be most welcome.
