Unlike aluminum measuring sticks, the 42 inch Deep Blue Starboard Fish Ruler will not mark your boat or rattle. This ruler is also engraved instead of printed, so the lettering will never wear out or fade away. Use it loose or mount to your dock or boat, measure fish, cover old decals or holes. Easily cut to length if needed and can also be drilled for permanent mounting. Available in white with black letters or black with white letters. Lifetime warranty provided by Deep Blue Marine.
