Designed with outdoor safety in mind, the TriReso system combines three whistle modules that produce distinct, multi-directional signals to ensure rescue calls are heard even in noisy and windy conditions.
- Three whistle modules combine for multi-frequency alerts
- Pealess design resists jamming from dust and sand
- Available in durable titanium or lightweight aluminum
What happened
Eck Design, known for outdoor gear innovations, has introduced the TriReso whistle system on Kickstarter. This modular device includes three independent whistle modules—the Alert, Power, and Echo Chambers—that can be used separately or magnetically combined into a single unit. Each module produces a distinctive sound frequency, and when combined, the whistle emits irregular frequency shifts to create a siren-like resonance.
This design aims to improve the whistle's effectiveness in various outdoor environments, including windy conditions, traffic, and noisy surroundings. With sound levels reaching up to 120 decibels and frequencies between 3,600 Hz and 4,800 Hz, the TriReso offers better signal clarity and audibility than conventional single-tone whistles.
Why it feels good
The TriReso’s modularity means that groups can share the whistles among members or attach all three to amplify their alert signals. The multi-directional sound output helps listeners locate the signal's source more easily, a significant advantage over traditional whistles that direct noise from just one opening. This feature enhances safety by increasing the chances of being heard and found during emergencies.
Its pealess design reduces moving parts, lowering the risk of dirt or sand jamming the whistle—common issues with classic whistles. Additionally, the inclusion of lanyard holes and slots for glow-in-the-dark tritium tubes (sold separately) means the whistle is both easy to carry and usable in low-light situations, offering reassuring reliability to outdoor enthusiasts.
What to enjoy or watch next
Interested adventurers can support the TriReso Kickstarter campaign, with early pledges starting at $44 for the aluminum model and $64 for the more durable titanium version. Once fully funded, shipments are anticipated to begin in October. The titanium whistles come in a natural gray finish, while aluminum versions are offered in bright orange, with additional color options available.
For those who appreciate compact, functional outdoor gear with emergency preparedness at its core, the TriReso provides an innovative stride forward. Stay tuned for further updates on user reviews and real-world performance as more backers receive their whistles and put them to the test outside.
