Someone needs to come up with a screw in insert that goes between the arrow shaft and the broadhead. Such a sensor could maybe be inserted and secured into the arrow shaft too. Or made to be part of the nock. The insert would have a sensor that is available for keychains already.
When you whistle the sensor in the arrow would whistle back.
