🙂 DO YOU KNOW WHY YOU SHOULD USE THIS PRODUCT?
  • Emergency situations can arise in diving, and it's crucial to have a reliable means of attracting attention, whether you're above or below the water's surface. Scuba divers have traditionally relied on whistles for audible surface signaling, but this method has limitations. What if a diver is incapacitated and unable to blow the whistle, rendering it useless? Moreover, if you need to alert someone who's too far away to hear the whistle, it won't serve its purpose. Additionally, there are instances when you need to get your dive buddy's attention, but they may be distracted and not notice your signals.
  • In contrast, Scuba Aquate Sub-Alert offers an effective solution by allowing divers to generate a loud, attention-grabbing sound on the surface, audible up to a mile away, or even signal a dive buddy underwater.
  • Scuba Aquate Sub-Alert is a specially designed, compact, and lightweight pneumatic signaling device that seamlessly integrates with your power inflator using quick-connect/disconnect hose fittings. Installation is a breeze and takes just moments.
  • What sets Scuba Aquate Sub-Alert apart is that it requires no modifications to your existing equipment, and it doesn't interfere with the normal operation of your gear.*
  • When you need to get someone's attention on the surface, simply squeeze the Scuba Aquate Sub-Alert, diverting a small amount of air from your scuba tank to create a powerful and piercing sound. Alternatively, when you're underwater and need to alert your dive buddy, a quick squeeze generates a buzzing noise, effectively capturing their attention.
  • Choose Scuba Aquate Sub-Alert for a reliable and versatile signaling solution to enhance your diving safety and communication.

🙂How is the Aquatec Sub-Alert different from a traditional whistle?➜ Whistles require blowing and are ineffective if the diver is unconscious or too far away. The Sub-Alert uses tank air with a simple squeeze, producing a powerful alarm both underwater and above water—a true upgrade in diver safety communication.

Scuba Aquatec AH-150 Alert Systems

🙂Why should divers use the Aquatec Sub-Alert?

➜In environments with limited visibility or strong currents, sound becomes the fastest and most reliable way to signal for help. The Sub-Alert produces a high-decibel tone that cuts through distance and background noise—keeping divers safe and connected.

🙂Is installation easy? Does it require modification?

➜No modification is needed. The quick-connect fitting attaches directly to your BCD’s low-pressure inflator hose, maintaining full inflator functionality. Installation takes only seconds.

🙂How does the Aquatec Sub-Alert truly help me in an emergency?

➜The Sub-Alert provides a high-decibel acoustic signal, serving as your fastest and most effective way to call for help when visibility is extremely low, currents are strong, or you've become separated from your buddy or boat. It penetrates underwater distances and noise, ensuring your presence is recognized, significantly increasing the chance of rescue, and providing you and your buddy with added peace of mind.

🙂I already have surface signaling devices (like SMBs or whistles); why do I still need an underwater acoustic signaling device?

➜Surface signaling devices are primarily for distress signals on the surface, whereas the Sub-Alert is specifically designed for the underwater environment. During a dive, if you need to immediately alert a buddy underwater, warn of danger, or call for help, surface signaling devices are ineffective. The Sub-Alert provides instant underwater communication capability that cannot be replaced by surface devices.

🙂What specific benefits does this alarm offer for the types of diving I do (e.g., night diving, technical diving)?

➜ For complex environments such as night dives, technical dives, or cave dives, the Sub-Alert is an indispensable safety tool. In these low-visibility or confined-space diving activities, an acoustic signal is often more reliable than a visual one. It can quickly draw a buddy's attention, help maintain team coordination, or provide a crucial means of communication during an emergency ascent or retreat.

🙂What are the advantages of the Aquatec Sub-Alert compared to other underwater alarms?

➜The Aquatec Sub-Alert is renowned for its reliable performance, easy installation (no BCD modification required), and superior volume output. It connects directly to your BCD's low-pressure inflator hose without affecting inflation functionality. Its robust and durable design is built to withstand harsh underwater conditions, providing lasting and effective safety assurance.

🙂Do dive centers or instructors recommend using the Aquatec Sub-Alert?

➜Many dive professionals and instructional organizations highly recommend that divers carry an underwater acoustic signaling device as part of their standard safety equipment. Due to its reliability and effectiveness, the Aquatec Sub-Alert is often chosen as ideal equipment for dive centers' rental gear or for instructors guiding groups, helping divers better manage underwater situations and ensuring the safety of all members.

  • ➜Technical and commercial divers who require reliable signaling.
