Neptonics Flashlight-Mounted Lobster Gauge

Overview

The Neptonics Flashlight-Mounted Lobster Gauge is a stainless steel measuring tool designed for checking California spiny lobster size underwater. It attaches to a dive flashlight, allowing divers to illuminate and measure their catch without handling a separate gauge.

Mounting and use

An adjustable metal band clamp secures the gauge around a compatible flashlight housing. This keeps the measuring opening near the light, making it easier to position the gauge and maintain visibility during nighttime dives.

To check lobster size, measure the carapace in a straight line along the center of the back, from the rear edge of the eye socket to the rear edge of the body shell. California regulations require divers to measure lobsters underwater and immediately release any that are undersized.
