A metal detector for detecting missing arrows includes a housing having a fastener for mounting to an arrow shaft. The detector includes an antenna, a circuit connected to the antenna for detecting the proximity of metallic arrow parts to the antenna, and an indicator connected to the circuit for indicating that the circuit detects the proximity of the antenna to a metal arrow part. Preferably, the housing includes a generally planar paddle portion supporting the antenna and a generally planar handle portion, the portions being at different parallel planes. The fastener includes a recess in the handle portion for receiving the end of the arrow shaft and a threaded fastener for fastening to a threaded recess on the arrow shaft extending into the recess.
