DescriptionCompetition-Grade. WDF Approved. — Caliburn Avalon Professional DartboardThe Caliburn Avalon is a professional-grade bristle dartboard built to meet competition standards — WDF approved and constructed with blade wire to reduce bounce-outs and maximise the scoring surface available to your darts. As a WDF-approved board, the Avalon meets the specifications used in official World Darts Federation-sanctioned events, making it suitable not only for serious home practice but for club and tournament use where board specification matters. Consequently, every session on the Avalon is a session on a board that plays the same as the boards used in organised competition — consistent, reliable, and built to perform over extended use.WDF Approved — What This MeansWDF (World Darts Federation) approval confirms that the Avalon meets the official specification for dartboards used in WDF-sanctioned competitive play. This covers board diameter, segment dimensions, wire construction, and surface consistency. For players who compete — or who want to practise on the same standard board used in official events — WDF approval is the definitive quality benchmark. It is a verified technical standard, not a marketing claim.Blade Wire — Why It MattersBlade wire (Avalon) — Thin triangular metal blades replace round wire in the segment dividers. The blade profile deflects dart tips into the scoring segment rather than bouncing them back out. The narrower wire also takes up less physical space, giving each scoring segment a marginally larger effective target area. The result is fewer bounce-outs and more darts staying in the board where they land.Round wire (standard) — Traditional round-section wire sits higher above the board surface. Darts landing on or near the wire are more likely to be deflected away from the segment and bounce out entirely. Functional but produces more bounce-outs than blade wire, particularly on edge hits.Bristle Construction — Built for Steel TipThe Avalon is a bristle dartboard made from tightly packed sisal fibres that grip the dart tip on impact and self-heal when the dart is removed, delivering a long service life under regular play. The Avalon is designed for use with steel tip darts only — soft tip plastic-tipped darts are not suitable for bristle boards.Key FeaturesWDF Approved — meets the official World Darts Federation specification for competitive play; suitable for club, tournament, and serious home practice useBlade wire construction — triangular blade wire profile deflects dart tips into segments rather than bouncing them out; larger effective scoring surface per segment compared to round wire boardsProfessional bristle surface — tightly packed sisal fibre construction; self-heals after dart removal and delivers long service life under regular playSteel tip compatible — designed for standard steel tip darts; not suitable for soft tip plastic-tipped dartsStandard competition dimensions — 451mm diameter with regulation segment sizing, consistent with WDF tournament specificationProduct SpecificationsName: Caliburn Avalon Professional DartboardWire type: Blade wireSurface: Bristle (sisal)Tip compatibility: Steel tip onlyApproval: WDF ApprovedDiameter: 451mm (regulation)Brand: CaliburnFrequently Asked QuestionsWhat does WDF Approved mean, and why does it matter? WDF (World Darts Federation) approval means the Avalon has been verified to meet the official specification used in WDF-sanctioned competitive events — covering the board’s physical dimensions, segment layout, surface construction, and wire standards. For players who compete in organised events or want to practise on a board identical to competition boards, WDF approval is the relevant benchmark.What is the practical benefit of blade wire over round wire? Blade wire reduces bounce-outs. The triangular blade profile deflects dart tips into the scoring segment rather than bouncing them back. Round wire has a larger contact surface more likely to cause deflection away from the board on edge hits. In practical terms, more of your darts stay in the board with blade wire — particularly on near-miss throws that clip the segment boundary.Can I use soft tip darts on this board? No — the Caliburn Avalon is a bristle dartboard for steel tip darts only. Soft tip plastic-tipped darts are not suitable for bristle boards and will not embed properly in the sisal surface. For soft tip play, an electronic dartboard is the appropriate choice.How do I extend the life of the board? Rotate the board regularly — most bristle boards have a removable number ring allowing you to rotate the segments and distribute wear evenly. The treble 20 bed receives the most play and will wear fastest without rotation. Remove darts straight out rather than at an angle to preserve the sisal fibres, and keep the board away from direct moisture.The Caliburn Avalon is a WDF-approved professional bristle dartboard with blade wire construction. For steel tip darts only.
