Daïve is building a head-up display dive computer that clips onto a standard dive mask and keeps core telemetry in your natural sightline, so you spend less time checking a wrist unit and more time tracking buoyancy, buddy position, and the environment. The pitch is “awareness without breaking flow”: depth, time, ascent-rate cues, no-deco context, and alerts are intended to sit just above your primary view rather than pulling your attention down. https://daivetech.com/
Unlike earlier HUD concepts that force you into a proprietary mask, their lock-mount approach aims to retrofit many popular mask frames, effectively turning the mask into a live info hub. The prototype shown here is split into three modules—electronics/PCB, battery, and an optical block—so the team can upgrade parts over time and keep service and sealing simpler. They also emphasize neutral buoyancy (positive floating) to avoid the “extra weight on the face” problem that can amplify jaw fatigue and mask leak risk.
The demo (filmed at CES Las Vegas 2026) focuses on how the image gets into the diver’s eye: a microdisplay with a folded near-eye optical path that reflects the rendered UI into a small virtual screen. Control is via a rotating selector so a diver can step through menus with gloves, rather than relying on tiny buttons. Air integration is part of the plan via a wireless pressure transmitter, letting remaining gas time and tank pressure live in the same HUD layer as depth and timing.
A second thread is team coordination: if multiple divers wear the system, it’s designed to support short-range buddy messaging (they cite around 10 m) with preset icons/phrases for common signals. They also talk about opening the software layer so third parties can build custom pages and interaction patterns—useful if you want task-specific overlays for training, photography, survey work, or structured technical profiles. The long-term direction hinted here is an underwater computing platform rather than a single accessory.
On readiness, Daïve says lab testing targets about 70 m today with a path toward deeper configurations (up to about 120 m), and their own materials mention wide temperature operation and redundant power concepts. They’re based in Beijing with manufacturing in Shenzhen, with a team of roughly 20, and they describe a Kickstarter launch around March with a fully functional unit planned by then. The interesting question will be how they validate reliability (battery margin, alert clarity, sealing strategy, and comm robustness) in the messy conditions real dives always bring.
