Cabela's Digital Fish Scale - $12.99

The Digital Scale displays exactly what your fish weighs to the nearest ounce all the way up to 50 pounds on an LCD screen. A backlit display feature makes reading the scale in low light easy. Weights can also be displayed in metric units. The scale is powered by three AAA batteries (not included) and will automatically turn off after four minutes of inactivity. Internal memory will store up to eight weights and will total them for you. This unit's taring feature will zero out the weight of a container and then produce a new reading after fish are added to the container. You can switch the scale between kilograms and pounds by holding both buttons simultaneously for 3 seconds. - $12.99
