Technical Diving Equipment

Choosing proper equipment for your technical diver training is essential for your success. The equipment used in technical diving has evolved for more than two decades and can be very specific often down to the smallest details. This comes down to performance and configuration for ease of use and streamlining.

It is strongly recommended that you discuss your equipment needs with your technical instructor at Ocean Quest prior to making any purchases.
