Using the principles of UniLab, the Sigma range of darts has been designed from the outset with barrel, shaft and flight all mathematically matched to form an optimum aerodynamic unit, specified to give true flight and greater accuracy.

Every Sigma dart has been mathematically optimized, creating a range of darts with the truest flight and greatest accuracy. The combination of the distinctive conical barrel shape and the ultra thin taper at the nose of the barrel result in the ultimate aerodynamic dart!

Precision cut square profile barrel grooves provide aggressive grip for precise control and each set is supplied with Sigma One shafts and Sigma One Flights for enhanced stability. Each barrel also comes with unique Sigma barrel engraving.

Upgrade to the Sigma Accuracy pack with Slikstik and Sigma Pro flight for enhanced precision.
