As an instructor, Rich uses a drysuit for almost all of his diving, and so he knows exactly what things are important in a drysuit when diving every day. He probably does over 200 dives every year in environments ranging from the Baltic wrecks to Balkan cave systems.
During his teaching he also sees a huge variety of suits used by his students. A good suit will keep a student warm and help them learn. It will make skills easier to perform and keep them fresh for multiple days of intense diving.
These factors place him in a unique position to help you specify a drysuit system that will not only keep you dry today, but be exactly the right suit to support your goals and dreams underwater in the coming years.
