Tyrant’s board is made out off heavy duty woven vinyl with a 3” plastic bump. This bump board will enable you to measure fish up to 64.25 inches. The board is 10 inches wide and rolls away to a 4 inch diameter by 10 inches tall. It also comes with a Tyrant girth measure. Space on fishing boats is critical, simply roll it out, measure your fish, wipe dry and roll it away.
