Easy, actually.
Mine had a warble-tone alarm in the parachute - the batteries last about an hour. Given the distance it drifted, it didn't help me as it took more than an hour to hike through the fields, across the stream, and across the farm to the approximate landing area. Some users use small smoke cannisters for tracking, and others even use radio transmitters and directional receivers to aid in recovery.
Since that loss, a company has introduced a reasonably priced telemetry module that can be placed in the avionics bay. It has a GPS receiver and a telemetry transmitter, which sends Longitude/Lattitude, Altitude, and speed info to the reciever. It will definitely be part of any future launch.
