Which Dive Alert is right for me?

The MINI HAMMERHEAD is a diver to diver signaling device, designed for simple quick contact with your buddy - at an affordable price.

Gone are the days of reaching for your knife to tap on your tank then fumbling with the slate to communicate your message. Now SIMPLE CODES can pass your message instantly.

The ERGONOMICALLY DESIGNED M-H connects inline with your power inflator, with the control button positioned so the divers hand automatically locates on it and activates it with ease - even in zero visibility.

The M-H has been engineered with efficiency and the highest priority. TO achieve the necessary power levels, the M-H. utilizes POWER VALVE TECHNOLOGY (P.V.T.). The P.V.T. is the heart of the system that synchronizes the delivery of pressurized air to a reciprocating piston, cycling at 18,000 rpm. The P.V.T. delivers snap-action control of compressed gas energy for an instant high powered acoustic signal with at absolute minimum air usage.

The M-H has a UNIQUE SIGNAL, a powerful low pitched buzz, the most attention grabbing sound a diver is ever likely to hear underwater. It reaches out to extreme ranges and enables accurate HOMING by divers, should they become separated.

The M-H is designed to last, with all high speed components, including the P.V.T. system, machined from self lubricating, space age polymers, for light weight, low wear rate and long CORROSION FREE life - qualities that metal components simply cannot match. The M-H is also fitted with and acoustically optimized exhaust valve to protect against sediment intrusion.

This BULLETPROOF design is based on quality materials, workmanship and simplicity in design and requires only basic periodical maintenance by the owner.
