To meet with the requirements of the technical diver, yellow seems to be emerging as the recognised colour for sending a pre-determined signal to the surface. The Aquatec Signal Mark is here to satisfy this need.
A very compact personal marker that rolls up small enough to be carried in the pocket of stab jacket or suit. 100% welded polyurethane coated fabric. A throat at the bottom of the tube restricts the air from escaping should the line be released. Very little air is needed to inflate.
Based on similar lines to the Tec Diver SMB, the Signal Mark will provide up to 5-6 Kgs. of positive buoyancy at the surface.
