The Bubba 18 Inch Fish Ruler makes sure you can quickly and easily measure fish lengths with perfect accuracy. The 90-degree upward fish stop makes a nice stop for the fish’s nose to land, while the high contrast ruler featuring ¼” measurements makes it a breeze to see the overall fish length. The Rulers feature anodized aluminum construction to withstand the elements and can be mounted to the boat or tethered for quick use.
