Personal Safety & Activity Logging for Divers and Open Water Swimmers
The netH2O-P is a compact, lightweight, and exceptionally rugged personal safety and tracking device designed specifically for professional divers, recreational divers, and open water swimmers. This innovative surface buoy provides continuous safety monitoring, GPS tracking, and comprehensive activity logging—delivering professional-grade capabilities in an accessible, user-friendly package.
Continuous Safety Monitoring with Cloud Connectivity
Throughout your dive or swim, the netH2O-P continuously transmits your precise GPS location and real-time water conditions to the cloud. This creates a persistent digital safety net: shore-based supervisors, dive boat crews, family members, or emergency contacts can monitor your position and environmental conditions in real-time through web or mobile interfaces.
All tracking data is strictly private by default—you maintain complete control over who can access your location information. For professional operations, this enables sophisticated fleet management and safety oversight. For recreational activities, it provides peace of mind for loved ones without compromising your privacy.
The Hybrid Solution: Connected Freedom
The netH2O-P represents an optimal middle ground between hard-linked surface connections (umbilicals, communication cables) and completely free diving. You maintain connection to the surface through a lightweight textile line—far less restrictive than traditional umbilicals—while retaining most benefits of hard connections: continuous location tracking, emergency signaling capability, and real-time surface communication.
Professional Dive Operations: Enhanced Oversight and Documentation
For professional diving operations in complex environments, the netH2O-P provides critical situational awareness without the logistical burden of traditional tethered systems. Dive supervisors can monitor multiple divers simultaneously, track progress through work sites, and maintain real-time awareness of environmental conditions affecting the team.
Automatic activity logging creates comprehensive documentation valuable for:
- Professional certifications - Verified dive profiles with GPS coordinates and environmental data
- Client reporting - Detailed records of inspection or maintenance activities
- Safety analysis - Historical data for post-dive debriefing and continuous improvement
- Regulatory compliance - Automated documentation meeting industry standards
Recreational Diving: Safety Without Complexity
For recreational divers, the netH2O-P introduces a transformative level of safety without the constraints or complexities of hard surface connections—which simply aren't compatible with casual diving activities. The system is lightweight, non-intrusive, and requires no special training beyond basic operation.
The buoy can be provided by diving centers as part of rental equipment packages, or purchased directly by individual divers who want personal safety equipment for all their diving activities. Either way, deployment is simple: connect the textile line to your BC or weight belt, deploy the buoy, and dive with confidence.
Multi-Modal Emergency Activation
When you need help, the netH2O-P provides two intuitive methods for emergency signaling:
- Acoustic activation - Generate a sequence of "clicks" with a handheld acoustic device (included)
- Mechanical activation - Traditional repeated hard pulls on the connecting line
Once activated, the buoy emits audible alerts and intermittent visual signals (light flashing) while continuously broadcasting your GPS position to designated emergency contacts.
Open Water Swimming: Visibility and Security
Open water swimmers face unique safety challenges: limited visibility to watercraft, changing currents, potential disorientation, and distance from shore. The netH2O-P addresses all of these concerns while adding valuable training insights.
The brightly colored surface buoy dramatically improves your visibility to boats, jet skis, and other watercraft—a critical safety feature in busy maritime areas. Real-time GPS tracking allows shore-based observers to monitor your progress and position. If you encounter difficulty, emergency activation immediately alerts your designated contacts with your exact location.
Comprehensive Activity Logging for Performance Analysis
Every session with netH2O-P is automatically logged with complete detail:
- GPS track with full route visualization
- Water temperature throughout activity
- Current strength and direction estimates
- Session duration and distance covered
- Environmental conditions (waves, weather)
For athletes and serious recreational users, this data becomes invaluable for training analysis, progress tracking, and experience documentation. Review your routes, analyze your performance in different conditions, and build a comprehensive portfolio of your aquatic adventures.
Emergency Response That Works Underwater
Unlike smartphone-based emergency systems, the netH2O-P can initiate emergency responses even while you're still submerged. The acoustic activation method works underwater—generate the click sequence below the surface, and the buoy receives and responds immediately. Your emergency signal is transmitted via cellular network directly to your pre-configured contact list, enabling rapid response coordination.
Difference from Beach Security Module
The netH2O-P personal configuration differs from the beach security module in its communication architecture. The personal device transmits emergency signals directly via cellular networks without requiring a local LoRa base station. However, the security module configuration (with land-based station) can also be applied to diving operations—for example, a dive boat can host the LoRa base station to provide local alarm capabilities plus internet relay.
Simple Operation, Professional Results
The netH2O-P requires no specialized technical knowledge. Setup takes minutes: charge the unit, configure your emergency contacts through the web interface, attach the line, and you're ready. The system handles all complexity automatically—you simply focus on your dive or swim.
Battery life supports extended activities without anxiety about power depletion. The rugged construction withstands harsh marine environments, and the compact form factor ensures it never interferes with your aquatic activities.
Peace of Mind, Quantified Performance, Enhanced Safety
Whether you're a professional diver conducting complex underwater operations, a recreational diver exploring new sites, or an open water swimmer training for distance events, the netH2O-P delivers three critical benefits: verified location sharing with trusted contacts, comprehensive activity documentation for later analysis, and reliable emergency signaling when you need help most.
Join divers and swimmers worldwide who have discovered that the netH2O-P transforms aquatic activities from inherently risky solo ventures into connected, documented, and much safer experiences.
