457 kHz frequency EN 300718

The PIEPS DSP SPORT is a 3 antenna avalanche transceiver with integrated Mark and Mask functions for easy use for companion rescue. Send-Search-Mark.
Searcher can MARK and MASK the signal of beacons in multiple burial situations.
The Pieps DSP SPORT has an unrivaled outstanding digital range. Our professional users are getting best case / best victim antennae alignment range pick ups at well over 74+ meters . Just amazing as this is equal to the analogue beacon ranges for first signal pick up.

The Pieps DSP SPORT utilizes the current Firmware that works with the PIEPS BACKUP beacon.
NO, the DSP SPORT DOES NOT work with the PIEPS TX600 Transmitters separate 457.600 Khz frequency.
It does work with PIEPS BACKUP beacon.
The DSP SPORT is similar to the DSP except that it does not include the SCAN feature, the Options Pack and does not work with the TX600.

Outstanding circular digital range: All around in all directions!
Ranges previously only known from analog beacons are reached now for the first time by the PIEPS DSP (DSP= Digital Signal Processor) using digital filter technology.
One of the main targets of the PIEPS development team was to achieve a best possible 'useful range'. All other beacons available on the market feature a more or less elliptical receiver range, that means a different range in different orientation of the receiver antenna in relation to the position of the transmitter. (best range with antennas 'face to face', worst range usually if antennas are angled by 90°). Furthermore the international standard for avalanche beacons EN 300718 allows a frequency deviation of the transmitted signal of +/- 80 Hz. In the case of most other receivers, a decrease of range is the result.
  • The PIEPS DSP is optimized in terms of 'circular receiver range' (same range in all antenna orientations) and constant receiver range over the whole frequency range.
3-antenna system:
The PIEPS DSP was the first avalanche beacon using a 3-antenna system!
  • The three dimensional system works especially well in the near proximity in deep burial situations
  • Eliminates the influence of the inclined flux lines
  • Extremely accurate locating irrespective of the position and depth of the buried person!
  • The PIEPS DSP allows exact pinpointing independent of the antenna-orientation and burial depth
  • Only one maxima is indicated corresponding to the point of lowest distance reading
  • Any confusion in the stressful situation in the event of an avalanche search has been eliminated by the unique operating technique of the DSP. This means saving valuable time!
SMART transmitter technology:
The smart transmitter is using a receiver simultaneously in order to detect signals of other beacons nearby. Transmitter signals are synchronized in relation to others and are transmitted right in between the signals of other beacons.
  • No more signal overlapping!
  • The smart transmitter is a great advantage in case of multiple burial search!
  • Faster and even more accurate location of avalanche victims by using the smart transmitter!
Two different transmitters A(blue) and B(light blue) are received by the receiver (purple) like one single signal. Because of the different periods of the signals, A and B periodical interference can be initiated. A clear signal isolation of the received signals will no longer be possible because of possible modulation and annihilation.
Transmitter signal A of the smart transmitter is synchronized and positioned in between the signals of transmitter B in order to avoid signal overlap!
Innovative SCAN, MARK, and MASK functions for multiple burial scenarios:
The optimized multiple search, the absolute highlight of the PIEPS DSP, is based on a signal separation by the Digital Signal Processor (DSP).
  • If there are multiple burials, this is clearly indicated by the number of matchstick men.
  • Once the position of the first victim has been located, the unit should be kept still and the MARK button pressed for approx. 3 seconds
  • This signal is now "masked" and the successful "masking" is confirmed by a frame around the symbol
  • The PIEPS DSP then begins its search for the next strongest signal automatically and the search can now be continued as needed
In the case of multible burials, an overlap of the signals of two or more beacons might occur. In addition to that some older analog beacons are sending a weak continuous signal between the pulsing main signals.
Because of the different characteristics of the signal formats, the sometimes signals can not be physically separated and therefore “masking” of signals can be delayed. However, in principle the “masking” of signals works and thereby considerably reduces the search time in the event of a multiple victim search.
iPROBE Support: The DSP can be temporarily deactivated by the iPROBE:
The PIEPS iPROBE Carbon avalanche probe is an avalanche probe with integrated digital technology. It provides a hit and proximity reading for every standard beacon transmitter and enables a brief deactivation of the detected transmitter (for transceivers with iPROBE support).
When the tip of the probe is about 2 meters from the transmitting beacon, the first acoustic signal is given (Piep_Piep) and the LED lights up. At a distance of about 50 cm a continuous sound (Piiiiiiiiiep) is emitted and the LED remains continuously on.
If the transmitting beacon supports the iPROBE function, the rescuer can deactivate it by pressing the MARK button (on the probe handle). By pressing the MARK button again for a longer time or by removing the iPROBE tip from the vicinity of the transmitting beacon (>50 cm), the deactivated transmitting beacon is activated once more.
