Upgraded this season (2004-05) with a faster processor.The Ortovox X1 is a combined Digital-Analogue transceiver that is very easy to use. The Ortovox X1 will behave like an analogue transeiver during the first part of the search, so that the searcher uses the strength of the audio signal to determine the best direction. This gives the greatest range. At about 20m the unit will automatically switch to digital mode and give a distance and direction indication in metres. Once under 2m the searcher is just about on top of the victim and the X1 uses sound and the distance reading. The Ortovox X1 combines the benefits of both analogue and digital technology. The casing is the same as the proven F1, with a simple body strap which ensures unit is switched on when worn.
