Page 7: Recco Reflector
▸ Diode fixed to a copper an- tenna, molded into plastic. ▸ Passive — no battery. ▸ Virtually unlimited lifespan — no maintenance. ▸ Works with all RECCO de- tectors. 4. RECCO TECHNOLOGY The detector’s directional an- tenna uses harmonic radar to generate a directional signal. -

5. RECCO BASICS 5.1 RANGE Relative affects on range caused by different mediums. up to 120 m Snow - dry up to 20 m Snow - wet up to 10 m Water up to 0.2 m 5.2 FACTORS AFFECTING RANGE... - Page 9 POLARISATION The RECCO system is polarized to achieve the best signal. When the antenna is parallel with the reflector the range and signal are at maximum. Therefore, rotate the detector 90 º slightly from side to side to seek the maximum signal.

Page 10: Detector Function Check
5.3 DETECTOR FUNCTION CHECK Prior to the start of winter and during the winter, routinely check the detector’s range and battery. RANGE CHECK 80+ m with reflector 1.5 m above the ground 10+ m with reflector on ground BATTERY CHECK The battery should operate for Refer to the detector about 2 hours at temperatures... -
Page 11: Detection Zone
5.4 DETECTION ZONE The detector’s area of best detection is basically a diamond- shaped area. At distance the sig- nal is very directional. Closer to the detector the signal is less di- rectional; a reflector can be off to one side. The signal can be lost either because the operator moved past the reflector, or when the signal... - Page 12 The detection zone shape is 3-dimensional, and its vertical shape is similar to its horizontal shape. Be sure to aim the detector toward the snow to get the best combination of signal range and signal depth.

Page 13: Detecting A Recco Signal
5.5 DETECTING A RECCO SIGNAL There are three key detector mo- vements that are used to detect and follow the RECCO signal. SWEEP The sweep movement is anytime the detector is moved from side to side. The sweep is used to de- tect the signal and to establish direction. - Page 14 TURN The turn movement is a slight turn of the wrist The turn is used to to re-aim the detector’s signal cone back to the reflector when the signal has ini- tially been lost. When the signal has been lost – and power was not changed: stop, turn only your wrist slightly to point detector to both sides...

Page 15: Reflectors On Detector Operator
Some uniforms have removable reflectors. Moveable reflectors may be re- moved, or moved to the opera- tor’s back. If producing a distracting signal, use a RECCO Shield or Vest. Fixed reflectors (boots, clothing, helmets, etc.) should be covered by a RECCO Shield. -
Page 16: Distracting Signals
6. DISTRACTING SIGNALS Do not attempt to search if you are immediately receiving a RECCO signal. This signal is likely coming from something on you or from close by rescuers. You need to identify and eliminate distracting signals before searching. -
Page 17: Managing Distracting Signals
The closer and more secure to your back, the better. If interfe- rence continues, shield the device. ▸ Shield: If necessary, cover the device or reflector with a RECCO Shield or Vest. These products are made from special electro- magnetic shielding fabric that blocks the RECCO signal but does not block the 457kHz transceiver signal. - Page 18 SEARCH METHODS...

Page 19: Basic Recco Search
▸ Eliminate distracting signals by moving devices (transceiver, GPS, radio, etc.) to your back, covering with RECCO shields or vest, or removing and leaving behind. ▸ When aiming the detector on max power toward a clear horizon and have no distracting signals you are ready to search. -
Page 20: Signal Search
1.2 SIGNAL SEARCH Goal: To detect a strong signal. The use of headphones is recom- mended Debris Scan Stand in one place – preferably at top or side of debris – and with the detector scan the debris. If no signal, start the systematic Signal Search in corridors. - Page 21 Aim about 4 m ahead Remember to keep the detector aimed downwards towards the snow surface, especially when searching across a slope or sear- ching downhill. In very irregular debris search around and over mounds and along troughs. SECOND PASS: 10 m wide search THIRD PASS: When a person corridors (search 5 m to right and is known to be buried –...

1.3 COARSE SEARCH - when first signal was received Goal: To establish direction, follow the signal to get close. Rotate ▸ Rotate the detector to the strongest signal. Hold detector in that position. ▸ Mark you position. Sweep ▸ Sweep quickly the detector from side to side – stop at strongest signal –... - Page 23 When following a signal hold the detector steady. Do not continue to sweep or rotate the detector while moving. TRANSITION FROM COURSE SEARCH TO FINE SEARCH Goal: To get the signal back. Turn When the signal has been lost – and power was not changed –...

Page 24: Fine Search
1.5 PINPOINT SEARCH Goal: To mark and confirm the prezise location. ▸ Use probe pole to confirm and determine burial depth. When you have detected a RECCO signal there are 4 variables that will affect the strength of the signal: ▸ Power ▸... -
Page 25: Advanced Search Techniques
To improve your chances of success the detector operator: ▸ Ask rescuers, if possible, to learn who might have RECCO Reflectors. ▸ Ask rescuers to stay behind the operator, if possible minimum 5 m behind. ▸ Keep your body between the detector and other rescuers. -
Page 26: Searching On Skis
2.2 SEARCHING ON SKIS On smooth avalanche debris it may be possible to search from skis. On skis you typically travel faster, which requires several slight adjustments to your search techniques. ▸ Decrease the width of search corridors. (Do not lose elevation too quickly.) ▸... -
Page 27: Searching For Multiple Burials
2.3 MULTIPLE BURIALS Three Circle Any time multiple burials are known or suspected, it is neces- sary to search the area around a found victim and back to where you first detected that signal. From the found victim step out Repeat two more circles, each 3 3 steps (~3 meters) and search meters off the previous circle. - Page 28 Tandem Burials If the detected signal is very wide then 2 victims are buried equidistant from the detector, and the reflectors are similarly aligned. Go in the direction of the middle of the signal until the signal is lost. When the signal has been lost – and power was not changed – because the signal cone is no longer pointed at the reflector, stop.

DEVICES Many electronic devices, including ▸ transceivers some listed below, may reflect a ▸ radios RECCO signal even when turned ▸ cell phones off; however, the range will be ▸ digital cameras very short ranging from centime- ▸ gps units ters to several meters. -
Page 30: Searching With Multiple Detectors
When using 2 (or more) detectors RECCO to search large debris areas use the ALT Switch to set each detec- tor to a different RECCO channel. The position – up or down – on a < 5 m 4 - 20 m single detector does not matter. -
Page 31: Searching For 457Khz Transceivers
3. SEARCHING FOR 457KHZ TRANSCEIVERS Any time there is an avalanche transceiver search the RECCO detector operator should also use the 457 kHz function to search for a transmitting avalanche rescue RECCO transceiver. 1. RECCO DETECTOR - Must be turned “ON”... - Page 32 The R9 detector may be used to locate a transceiver. The detector operator uses the R9 like an ana- log transceiver and locates the signal using either the tangent or...
