## What is Guardian Pro?

OLAS Guardian Pro App – Precision Control for Professional Operators

The OLAS Guardian Pro app enables firmware updates and advanced setup for the Guardian Pro wireless engine cut-off system. Designed for commercial and multi-operator vessels, the app ensures seamless operation and safety with intelligent tag tracking and customisable settings.

Key Features:

Automatic Helm Tag Recognition: The first tag detected within range is automatically set as the helm tag, with all other tags ignored - ideal for vessels with multiple users.

Custom Helm Calibration: Easily calibrate the cut-off distance between the helm and tag to suit your vessel layout.

Adjustable Detection Time: Set how long a tag can disconnect before triggering the engine cut-off, useful on larger vessels or for temporary movement.

Pre-Alarm Alert: Customise a warning delay before the engine stops, giving operators the chance to reconnect or override.

Battery Monitoring: View the current battery status of connected OLAS tags for reliable operation at all times.

Perfect for professional use, the OLAS Guardian Pro app offers precise control and streamlined safety management on the water.
