No matter whether you are under or over it, the S1+ combines the best of every situation!

The S1+ combines two unique avalanche transceiver innovations: the display showing the relative position of victims and the SMART-ANTENNA-TECHNOLOGY(TM)

Handling the device is more intuitive than ever. Once switched on it transmits, but when opened up 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.

The avalanche switchover and SMART-ANTENNA-TECHNOLOGY(TM) provide additional safety for the user, while the economic power management means that just two batteries are sufficient for 250 hours in transmission mode. The device can be updated.

Be found easier!

  • Precise fine search with visual support
  • Fast and reliable flagging function


The integrated Smart-Antenna-Technology analyzes the position of the antennas in the avalanche and automatically switches to the best transmission antenna. The result: Almost double the range in the worst coupling position, regardless of the beacon used for searching.

Secondary Avalanche Switchover

There is a motion sensor in the S1+ to enable secondary avalanche switchover. If the sensor has not detected any motion for 60 or 100 seconds during the search, it automatically switches back to transmit mode. Thus rescuers can also be found if there has been a secondary avalanche.

Recco Reflector Inside

The 3+ is also equipped with a Recco reflector. Recco helps professional rescuers find victims buried in the snow even faster. This offers an additional possibility of being found quickly. The backup technology is used by more than 700 ski areas and rescue teams around the world.

Intuitive Design

To make the search situation as simple as possible, the S1+ need only be flipped open in order to enter the locating mode. Neither keys nor buttons need to be pressed - simple snap open is enough and the digital device scans the avalanche cone automatically.

Visual and Acoustic Searching

With the S1+, you have the entire avalanche situation in view; the relative positions of all buried victims are shown. The lit display is reassuring and enables several rescuers to work together in a coordinated search action. The patented circle diagram combined with arrows and distance indication helps with the fine search. The intuitive search acoustics provide additional support throughout the entire rescue action.

Flagging Function

The number of people buried is shown in a list on the display of the S1+. As soon as you have found the first one, you can quickly and reliably block out the signal with the flagging button. The buried person is shown as being flagged, and you can continue searching for the others.
