Tighter Groupings – Thanks to 90% tungsten barrels

High-density 90% tungsten permits narrower barrel profiles while retaining mass, reducing deflection when darts cluster closely. Slimmer barrels make it easier for darts to land beside previous throws without moving them.

Improved shot placement and tighter trebles lead to higher scoring potential. Players find fewer bounce-outs and more consistent results during practice and matches.

Secure Throw Control – With pro-tested advanced grip technology

Harrows R&D developed an enhanced grip pattern tested by professional players to increase friction and hand stability during release. Textured zones on the barrel help position fingers consistently.

More predictable releases create repeatable flight paths and steadier scoring under pressure. Grip security reduces mid-throw slips and gives confidence in match situations.

Ready-to-Play Convenience – With a 16-piece bundle including spare stems, flights and travel case

The set contains three Caliber darts plus extra dart stems and Marathon flights in various colours, all housed in a compact travel case for protection. Harrows stems are designed for a vice-like flight grip to reduce detachment.

Players can personalise setups, replace worn parts quickly and transport gear safely to leagues. Less downtime means longer practice sessions and fewer interruptions during matches.
