Your cart is empty. Doryman Shellfish Calipers can be set from 3 to 6 1/2 inches to measure lobsters and crabs to specific legal sizes. While they float, these calipers also employ an attached lanyard to avoid any dropping mistakes. When the caliper is fully extended it becomes a 9 inch straight edge rule. When collapsed it can easily fit into a pocket. An easy twist knob regulates the calipers size and can be used to lock in measurements. These calipers have four color options: Blue, Green, Red, and Yellow.

The idea of this thing is cool. However, it's a cheap piece of garbage. Don't waste your time and money. I just keep it as an extra incase I lose my other one while on the water.

Product as described. Flimsy but gets the job done. Would recommend a fixed measuring device.

Really enjoy the ability to adjust the ruler for different situations or seasons. I think that it was worth the price
