Fantastic final dive of the IANTD Trimix KISS CCR Diver course at the Tulamben Drop-Off. Ideal conditions and great visibility made for an awesome final dive after a hard and intensive week of training with over 700mins of in water time completed. We encountered the usual icy thermocline at 87m, but I was toasty warm in the new Fourth Element Proteus 5mm suit. Big congratulations to Mike Hortin who is now a successful member of the century club and the entire Tekdeep team hope you enjoy it.
