The Fox 40 Classic is an essential surface signaling device for scuba divers, engineered to perform in the most demanding marine environments. Known as the first pealess whistle, its 3-chamber design eliminates moving parts, ensuring it won't jam, freeze, or deteriorate from exposure to saltwater and UV rays.

FEATURES

• Self-Clearing Chambers: The whistle features specialized chambers that instantly clear water when submerged, allowing you to produce a sharp blast the moment you hit the surface.
• Extreme Volume: It emits an intense 115 dB sound that can be heard up to one mile away, easily cutting through the roar of boat engines, breaking waves, and high winds.
• Failsafe Design: Because there is no "pea" to get stuck or collect bacteria, it remains flawless and reliable whether it is wet or dry.
• Professional Standard: It is a standard choice for the Coast Guard, search and rescue professionals, and marine safety teams worldwide.
