Neptonics Abalone Gauge

Overview

The Neptonics Abalone Gauge is a fixed-span shellfish measuring tool for checking abalone shell size while diving. Available measurement spans support either minimum-size checks or larger trophy-size reference measurements.

Measuring abalone

Position the gauge across the shell at its longest diameter to compare the shell with the fixed measurement span. This provides a direct reference without relying on estimated size before an abalone is retained.

Regulatory use

Abalone seasons, harvest areas, minimum sizes, and required measuring equipment can change. Confirm current regulations for the location being fished before use; a trophy-size gauge may not replace a separate measuring device required by local law.
