11/32 Whistling Signal Arrow

11/32 Whistling Signal Arrow with Stained Spruce Shaft and Brass Acoustic Point

Construction and Acoustic Features

The foundation of this arrow is a sturdy 11/32" diameter shaft made from split spruce, stained for enhanced durability and an authentic period look. The standout feature is the acoustic brass point. It operates on the principle of a whistle – as the arrow gains velocity, air flows through the precision-drilled holes in the tip, creating a distinct whistling or howling sound. To ensure stability despite the heavier brass tip, the arrow is fletched with 5-inch natural Shield feathers, providing an excellent flight profile.

The arrow comes fully assembled with one barred grey cock feather and two solid-coloured hen feathers, making it easy to nock correctly. The white plastic nock ensures high visibility once the arrow is in the target.

Technical Specifications

Recommended Bow Parameters

This arrow features a spine rating of 50–55 lbs. It is perfectly suited for traditional longbows, flatbows, or horse bows with a corresponding draw weight of 50 to 55 lbs. At this power level, the arrow reaches the optimal speed required to generate the best acoustic effect. Using this arrow with significantly lighter bows may result in a faint or non-existent sound.

Practical Advice and Maintenance

To ensure your signal arrows last for many seasons, follow these guidelines:

• Choose your target wisely: Only shoot into soft target butts made of straw or foam. Hitting hard objects like stones, trees, or plywood will dent the brass tip and potentially ruin its acoustic properties.
• Wood care: Spruce is a natural material. If your arrows get wet during training, dry them with a soft cloth and store them in a dry place. Avoid placing them near radiators, as extreme heat can cause the wood to warp or crack.
• Tip Maintenance: Periodically check the holes in the brass tip for debris or foam residue. Clean holes are essential for a clear and loud whistle.

Interesting Fact: Whistling arrows have a long history, particularly in the Far East. They were used by generals to command vast armies, with different pitches indicating various manoeuvres, effectively acting as the "radio" of the ancient battlefield.

Recommended Accessories

To protect these specialised arrows, we recommend a high-quality leather back quiver that can accommodate the slightly wider brass tips. Consider using arrow wood wax to keep the shafts protected from moisture and feather conditioner to keep the fletching in top shape after use in the field.
