The TriReso is a three-piece emergency whistle system designed to deliver multiple sound frequencies for improved audibility in outdoor and emergency situations. Developed by Spark Cube, each module functions independently and is tuned to a specific frequency, producing outputs between 100 and 110 decibels. Combined, the modules generate an irregular multi-frequency signal reaching up to 120 decibels across a 3,600Hz to 4,800Hz range. Hidden magnets, alignment grooves, and a triple-lock mechanism secure the modules together while allowing them to be separated for individual use.
Constructed from titanium or aluminum, the pealess whistle is designed to perform reliably without moving parts that can freeze or jam. Each module includes a slot for an optional tritium tube to improve visibility in low-light conditions, and the system can be clipped to a keychain, backpack, or lanyard for everyday carry.
