Ortovox - S1+
The Ortovox S1+ combines the success stories of two unique transceiver innovations: the display of the relative location of avalanche victims and the SMART-ANTENNA-TECHNOLOGY. This unique beacon has two distinguishing features: it has a flip-style design and a map of the victim burials, as opposed to simple directional/distance indicators.
Handling the device is more intuitive than ever. Once switched on, it transmits, but when opened up flip-phone-style it switches straight to search mode. The illuminated 360° real-time display shows the position in the avalanche and gives unmistakable action instructions. As soon as the person searching begins the pinpoint search, the patented circular display and intuitive search acoustics help the location process. Located victims can now be flagged and the search can continue. Follow-up avalanche switchover and SMART-ANTENNA-TECHNOLOGY provide a safety plus for the user, while the economic power management protects the environment and your wallet - just two batteries are sufficient for 250 hours in transmission mode. Of course the device can be updated.
The S1+ works incredibly easily and intuitively! It is turned on by the side safety switch. A standardized self-test runs automatically. All 3 antennas are checked for transmission and receiving functions, as well as for the battery status and the sensor. Then the device immediately switches to transmission mode. During the transmission mode, the transmitter is also constantly monitored and issues immediate notification when there is a malfunction.
In the worst case of a burial, how quickly you will be found by your companions depends on your location in the avalanche. This is called a coupling position. An axial coupling position is optimal - when your transmitter has the longest range. A vertical position is bad, since the range collapses by about 52%. In this situation, the S1+ uses the patented SMART-ANTENNA-TECHNOLOGY. It analyzes the position of the antennas and automatically switches to the best transmitting antenna. The result: you get 43% more range than with all other devices on the market (with the exception of 3+), entirely independent of the search device of your companion!
For maximum protection, the S1+ is equipped with a Recco reflector. Recco helps professional rescuers find victims buried in the snow even faster. The backup technology is used by more than 700 ski areas and rescue teams around the world.
Ease of use is key to a quick rescue. The large, illuminated 360° real-time display gives you detailed instructions on what you have to do. First, you will get the prompt to go in a meandering manner around the avalanche cone, until you receive an initial signal. The search strip width amounts to 50 m for the S1+. You will receive an initial signal even at a distance of 55 m to the victim. The relative position of the victim is immediately indicated in the display. Bearing lines, direction arrow and distance information lead you along the fastest route to the strongest transmission signal. From a distance of 4 meters, you are supported in the detection by a patented circular and trend indicator as well as the intuitive search acoustics. Once you've found the shortest distance to the victim, you can mark it. The victim appears in the display as located and you can (in the case of a multiple burial) continue with the search. The relative positions of up to 4 buried victims are directly shown in the display; for more than 4 victims a 4+ symbol will appear.
The S1+ has a long bar of special features that make the device unique. It works extremely precisely already in the partner/group test. Tested are: transmission frequency, pulse duration and transmission period. The S1+ scores points in the professional field too: it has a professional mode for mass burials that make searching more efficient. Additionally, the display of the relative position of the buried victims enables a coordinated search, because the next signal need not necessarily be addressed. Another special mode for deep burials helps professionals, like all others, to easily locate the deeply buried victims. Even in case of a follow-up avalanche, you are on the safe side with the S1+. If the device doesn't move for 60 or 120 seconds, it automatically switches back to transmission mode. In addition, the device has a slope inclinometer and numerous setup functions: contrast of the display, volume control, as well as a personalization feature with which you can name your device.
