Don't Look Up.
Wearable drone detection system
A compact, helmet mounted drone detection system providing real time early warning against aerial threats. Detects and classifies hundreds of commercial and tactical drone types at distances exceeding 1 km, with an instant audio alert delivered directly to the operator's helmet.
Silent watch.
Instant warning.
DLU is built for operators who cannot afford to look away. Helmet mounted and entirely passive, it continuously scans the RF spectrum used by commercial and tactical drones, evaluates threat confidence in real time, and delivers an audio alert through an in helmet speaker, no screen, no glance, no emissions.
At 15 grams, it disappears into the kit. In use, it becomes the sixth sense that keeps the head down and the mission moving.
Engineered for the helmet.
100+ Drone Types
Classifies commercial and tactical UAS across the full RF signature library.
Ultra Lightweight
15 g total sensor mass. Imperceptible on an already loaded helmet.
> 1 km Range
Horizontal and vertical detection out to 1 km,
with 360° coverage.
8 Hour Runtime
Runs on standard issue battery packs for a full operational shift.
Helmet Audio Alert
Direct audio into comms.
Zero look, zero fumble warning delivery.
Passive RF
No emissions. Undetectable by adversaries, safe in EMCON-strict environments.
Velcro Mount
Attaches in seconds to any standard combat helmet.
No tools required.
FOTA Updates
Signature library and firmware update over the air, no tear down.
TWO SYSTEMS.
one task.
Same helmet. Same audio cue. Same 15 g footprint. The thermal variant adds visual confirmation and the only practical answer to RF silent fiber optic threats.

What thermal adds.
From RF to
alert in real time.
DLU continuously scans the RF bands used by commercial and tactical drones. On contact, the signal is classified, threat confidence evaluated, and an alert routed to the operator's helmet audio, all while the system remains fully passive, with zero RF emissions.
