3Rivers Arrow Spin Tester / Square DeviceItem Number: 561901
Accuracy is key whether you're bowhunting or target shooting. The 3Rivers Arrow Spinner lets you check arrow straightness, broadhead and nock alignment, and fletching balance to ensure accuracy and consistency.
This is the perfect tool for arrow builders, as it allows you to detect bends or curves in the arrow shaft. You can also check for balance and alignment after installing inserts, outserts, points, or nocks.
Features high-precision SS bearings to support the arrow shaft and provide smooth operation. It also doubles as a squaring device, allowing you to grind the burs on a cut shaft using the included arrow shaft polishing assembly with adhesive sandpaper.
The main body is composed of premium aluminum alloy for durability and long life. Features a stable base to firmly set on a level surface while operating.
Measures approximately 11-3/4" x 2-1/4" x 1-1/2". Weighs approximately 15 ounces.
