The Dry Suit Diver Course will open up a whole new world of diving to you. Many of the diving environments around the world are better experienced in a dry suit. Why? These areas have an abundance of marine life waiting to be seen and photographed – they just happen to be a little colder! Dry suits are also used in tropical water during the cooler months.
This course allows the student to develop the knowledge and skills to properly use a dry suit. It will discuss the types of dry suits, accessories, maintenance and how to make basic repairs.
There are many different dry suit materials (neoprene, crushed neoprene, vulcanised rubber, trilaminate) but nowadays for recreational dry suit diving there are 2 main types – neoprene and membrane/trilaminate.
Trilaminate is made up of three layers as the name suggests and will keep you dry but does not give much insulation. Cordura or membrane types are particularly robust and are often used as school suits for this reason. These have a generally looser fit on the body to allow you to add more insulation underneath.
Crushed neoprene is thicker and has better insulating qualities than a trilaminate suit so will keep you warmer with minimal undersuit. It is a much more fitted suit and we find it much easier to move in, but it is easier to damage/puncture.
