FAQs
Are these darts suitable for beginners?
Yes, their stable center-weighted design is excellent for beginners who want to develop a consistent throw, though the aggressive grip may take time to get used to.
Can these be used on electronic dartboards?
No. These are steel-tip darts designed specifically for sisal/bristle boards. Using them on an electronic board will damage the sensors and the dart.
What does the 25g weight mean?
The 25g refers to the weight of the barrel only, excluding the flight and shaft. This is a standard weight for steel-tip darts, offering a good balance of momentum and control.
How often should I sharpen the points?
Check the points before each session. If you feel any burrs or notice the point is blunt, use a handheld dart stone to gently smooth the metal.
What is Astro-Grip?
Astro-Grip is Winmau's signature machining process that creates deep, multi-directional grooves in the tungsten barrel for a superior, locked-in feel.
Troubleshooting
Dart bouncing out of the board
Ensure the dart is landing at a proper entry angle; if bounce-outs persist, check if the points have become dulled or burred and use a dart sharpener.
Excessive wobble during flight
Check that the shafts are securely tightened to the barrels and experiment with different flight shapes (e.g., Slim vs. Kite) to stabilize the trajectory.

Setup, Compatibility & Care
To maximize the lifespan of your Winmau Callisto 02 darts, ensure you are using them exclusively with regulation sisal (bristle) dartboards. Avoid throwing against hard surfaces, as this will blunt or snap the steel points. To maintain the effectiveness of the Astro-Grip texture, clean the barrels periodically using a soft-bristle brush to remove dust and skin oils that accumulate in the micro-grooves. When customizing, these darts are compatible with standard 2BA shafts and any universal dart flights, allowing you to fine-tune the center of gravity to match your specific throwing style.
