Two instruments. The whole picture.
Open the throttle, break the signal, change the light.
This is a cockpit you can put to the test.

Engine data: live. Phone GPS: available · 74° course.
Move the throttle. Watch RPM, GPS speed and chart course respond together.
The information is already there.
HydraGauge brings it from your watercraft to the place you can actually use it.

A compact Bluetooth gateway brings the machine to your phone. Monitoring is the focus of HydraGauge 1.0.
Engine readings and phone GPS share one cockpit. Each keeps its source visible, so you can see what is still available.
A useful instrument tells you when its data can be trusted. Explore the idea with a fictional sample.
Choose a scenario to see why a reading appears—or stays unavailable.

HydraGauge is a gateway and companion app in development. Here’s the intended setup, and what’s still to be confirmed.
A HydraGauge gateway and the right adapter for your craft connect the engine to the app.
A compatible phone runs the companion app. Launch platforms and minimum requirements are still being confirmed.
Plan for a suitable phone mount and safety tether. Installation guidance will follow the validated hardware setup.
Support depends on the exact make, model and year. Compatibility is being validated before launch.
Tell us what you ride when you request updates. It helps us understand interest; it does not confirm compatibility or reserve a product.
A little preparation makes room for a better ride.
We’re validating compatibility one make, model and year at a time. The connector alone does not establish support. Leave your craft details with your launch update request to help us understand interest; we’ll announce confirmed coverage when it is ready.
This is an interactive concept showing the direction of the app and gateway. Telemetry, engine alerts and chart movement are simulated. The bathymetric chart is illustrative, not a navigational chart. Features and launch compatibility will be confirmed through validation.
The demo marks engine data as delayed, then marks it unavailable after two seconds. RPM, fuel, temperature, voltage and trim become “--”. Simulated phone GPS continues independently. Try the “Disconnect Bluetooth” control to see it happen.
The HydraGauge 1.0 product direction is monitoring and ride context. Engine start, throttle, steering, ECU writes and tuning are outside the 1.0 product scope.
