The Fathom is made of 5mm thick leather. It is double-layered and measures up to 130 centimeters, as it’s only a matter of time before a salmon of that size is caught again. This Fathom is thicker, longer, and features larger markings. It is available in three colors: rustic black, rustic brown, and burgundy. Custom markings can be added to the Fathom, such as the owner’s initials or the length of the large salmon already caught.
