The Logan Brass Turbo – Precision engineered from a solid piece of high-grade brass, the two-hole design creates a unique set of tones which can be heard clearly at distance in very challenging conditions – such as in fog, rain or wind – or when working in hilly or scrubby terrain. Also appreciated for its ability to cut through background noise such as traffic or crowd noise – so a great urban whistle too. Pairs beautifully with the Leather Lanyard.
