I've just seen the Ethics archery Spin Point on archery 360's list of new things from the ATA show.
They have an insert for arrows which has a point that can spin. A regular target arrow point, mind you.
Here's the spiel:
When an arrow spins it also has to spin the weight of the arrow point; the mass of the arrow point slows down the rotation of the arrow. The Ethics Archery Spin Points are arrow points that spin independently of the arrow, which allows the arrow to spin faster. A faster spin rate means a more stable arrow for increased accuracy and efficient arrow flight.
Now read about their spinning broadhead mount:
With the Spinning Insert, the broadhead does not spin at the same rate as the arrow shaft. This dramatically lessens the broadhead’s steering and wind plane. The Spinning Insert allows fixed-blade broadheads to fly like mechanicals or field points (with a properly tuned bow).
Please discuss this one.
