The Ortovox F1 Focus is the most popular Avalanche Tranceiver ever! The F1 avalanche beacon is widely used by ski patrollers and mountain guides in the US and Europe. This reliable analog only beacon uses a three colored signal strength indicator in the shape of an arrow together with a loudspeaker to lead you quickly to the buried transceiver using the traditional grid search method. Recognized around the world as the leader in analog technology.
The Ortovox f1 focus Avalanche Beacon is the most widely sold avalanche transceiver worldwide and is a long-standing favorite with professionals. The analogue technique of the f1 focus is completed by a visual search indicator. If you put on the f1 with its lightweight one belt system, the device is automatically switched on. There is only one rotary switch for switch-over from transmit to receive mode. Under ideal conditions the f1 can achieve a range of about 80 m.
The F1 Focus features a distinct loudspeaker and a three-light visual indicator. It has an effective operational range up to 70 meters. The ergonomic case is water resistant and exceptionally durable. You can expect over 250 hours of use from two fresh Alkali-Mangan batteries. IMPORTANT NOTE: The Ortovox M1 and F1Focus avalanche transceivers transmit and receive only on frequency 457kHz, the accepted standard frequency for avalanche transceivers in Europe and Canada. These transceivers are not compatible with those that transmit and receive solely on frequency 2.275kHz. It is your responsibility to verify that all members in your party have transceivers with compatible frequencies. Remember that wearing a transceiver is not enough. You and all of your party members must be well trained and practiced in using them for effective avalanche recovery.

There is only one rotary switch for switch-over from transmit to receive mode. Under ideal conditions the f1 can achieve a range of about 80 m. Thus the search path can be shortened and you get faster to the buried person. The number of beeps indicate at the same time if you have to face a multiple burial situation. The visual search indicator shaped in an LED arrow doesn't only show the right way, but also when you have to turn the volume control switch for adjusting the receiver sensibility. In case of several buried persons the volume control switch serves to isolate the signals and to ensure an easy and safe search. If you have several searchers, an earphone is highly recommended. The earphone plug-in is located at the waterproof, shock-resistant and ergonomic casing. In case of a second avalanche you can use the express emergency switch-over from receive to transmit mode. The f1 uses 2 easily available AA batteries. The waterproof, shock-resistant and ergonomic casing has an earphone connection socket. The f1 surpasses the demands of the European standard 300 718 and is also available as a set with earphone and bag. ORTOVOX recommends regular training to get familiar with the avalanche transceiver. We also strongly recommend that a transceiver must always be accompanied by a shovel and a probe on your tours.
