GRAN EYE G2 – Device Compatibility & Technical Specifications

GRAN EYE G2 is the updated AI-powered auto-scoring system for steel tip darts.

Using advanced dual-camera AI technology, GRAN EYE G2 automatically detects where your darts land and calculates scores with exceptional accuracy — no sensor board required.

Designed by GRAN DARTS, the system works with most standard bristle dartboards and delivers high-accuracy scoring, throw tracking, and streaming capabilities for practice, home play, and league environments.

The G2 model features an updated magnetic mounting system for easier installation and improved setup flexibility.

📱 Device Compatibility — Check Before Purchase

You don't need the latest high-performance device to use GRAN EYE.

GRAN EYE can be used with a wide range of smartphones and tablets, including older models and entry-level devices.

The best way to determine whether your specific smartphone or tablet is compatible is to run the AI Model Test in the free GranDarts app.

You can perform this test before purchasing GRAN EYE. A GRAN EYE unit is not required to run the test.

How to Check Your Device

Using the smartphone or tablet you plan to use with GRAN EYE:

  1. Install the GranDarts App or update it to the latest version.

  2. Log in to your GRAN DARTS account or create a new account.

  3. Create or select a Steel player.

  4. Tap the camera icon in the upper-right corner of the app's Home screen.

  5. Follow the on-screen instructions to start the AI Model Test.

  6. If the test completes successfully, you can use GRAN EYE with that device.
