Neptonics Fish Rattle

Overview

The Neptonics Fish Rattle is an underwater sound-producing tool for attracting fish during spearfishing and for getting another diver's attention while scuba diving. It is operated by shaking it underwater when an audible cue is needed.

Sound and operation

Shaking the rattle moves the internal BBs inside its metal chamber, producing a pronounced rattling sound described as similar to rocks being scraped together underwater. This provides an additional sound-based attraction method during a hunt and can also serve as a simple audible signal between divers.
