What frequency do avalanche beacons use?
457 kHz
An avalanche transceiver is an electromagnetic radio signal emitter and receiver. The radio waves they emit have a 457 kHz frequency, which is inaudible and a few hundred kHz below your typical AM radio signal. Think as a beacon as a super low power radio station that plays some music.
How successful is an avalanche beacon?
For people who practice regularly, however, beacons have saved many lives and they work very well. In addition, about a quarter of avalanche victims die from hitting trees and rocks on the way down, so beacons can only help the other three quarters who survive the ride before getting buried.
Are all avalanche beacons compatible?
This is a common question people have; “do all avalanche beacons work on the same frequency? The answer is yes; all beacons made in the last 15 or so years work on 457 kHz frequency and can all be used interchangeably.
How much is an avalanche beacon?
Avalanche Beacon Comparison Table

|---|---|---|
| Backcountry Access Tracker3 | $350 | 250 hours |
| Ortovox Zoom+ | $260 | 250 hours |
| Mammut Barryvox S | $500 | 300 hours |

Is the BCA Tracker 1 outdated?
The Tracker DTS is discontinued as of Fall 2018 However, it is no longer the best.
Do avalanche beacons expire?
If it’s older than 10 years, replace it. If you decide to replace your old beacon, consider keeping it for personal rescue practice or donating it to your local avalanche center or an avalanche instructor for training purposes.
Are black diamond beacons good?
The Black Diamond Guide BT is an excellent avalanche beacon. While we undoubtedly find this beacon to be sweet and easy to use given its advanced features, most backcountry users will not require a beacon with this level of sophistication.
Does the Tracker 2 have 3 antennas?
Summary: The Tracker2 is a three-antenna transceiver from Backcountry Access (BCA).
Is BCA Tracker 2 still good?
The BCA Tracker2 used to be one of best overall performing beacons on the market. While it is slowly getting passed by several similarly priced all-arounder models, it remains a solid beacon.
When should I retire avalanche beacon?
The older an avalanche transceiver is, the more its performance declines, which might be evident in its range, for example. PIEPS recommends sending in its devices for a service at 3 years and 5 years, and then every year after that.

Is a tracker 2 still a good beacon?
Can you breathe under an avalanche?
Abstract. Breathing under snow, e.g. while buried by a snow avalanche, is possible in the presence of an air pocket, but limited in time as hypoxia and hypercapnia rapidly develop.
What is the best way to transmit a 472 kHz signal?
A 472 kHz transmitter. This is the simplest solution, but will limit the transmit modes to CW (including QRSS and Opera). A 472 kHz transverter. This is a bit more complicated but will allow you to use all popular modes. A 472 kHz upconvertor. The audio signal is upconverted to 472-479 kHz.
What is a 472 kHz upconvertor?
A 472 kHz upconvertor. The audio signal is upconverted to 472-479 kHz. This will allow all modes. A special design is needed in order to suppress all unwanted mixing products and carriers. Modification of an existing HF transceiver (see ” Getting started “).
Can you listen to 472 kHz with homebrew?
Although most HF transceivers will allow you to listen on 472 kHz, only a few can transmit here. And even if they can, the output power is often limited. So, unless you buy a JUMA TX500 or a TVTR1 630 m transverter , homebrew is the only way to get on the air.
What is the frequency range of avalanche transceivers?
Early avalanche transceivers transmitted at 2.275 kHz. In 1986, the international frequency standard of 457 kHz was adopted, and this remains the standard today. Many companies manufacture transceivers that comply with this standard.
How do you test a avalanche transceiver?
Starting approximately 200 feet from the transmitting beacon:
- Switch your transceiver to receive (aka Search).
- Point your transceiver directly at the transmitting beacon.
- Walk toward the transmitting beacon.
- Note the distance when your transceiver receives a signal.
How does an avalanche transceiver work?
When turned on, the beacon transmits an electronic “beep” about once per second. Then, if someone is buried, everyone else in the party turns their beacon to receive, and they can hear the signal from the buried victim’s beacon; the signal gets stronger the closer you get.
Are all avalanche transceivers compatible?
The only thing you need to know is that all avalanche beacons operate on the same frequency (457 kHz) and are therefore fully compatible. That means you can search for any avalanche beacon with any other avalanche beacon on the market.
What is Recco avalanche rescue system?
The RECCO® system is a technology which helps rescuers to find victims of avalanche buriers or to search for people which got lost in the outdoors. And it helps the victims to be searchable during such accidents. It consists out of two parts, a detector and a reflector.
How do I find the avalanche beacon?
Once you have located a signal slow down and begin your coarse search. Align your beacon with the strongest signal and follow that curved path to within three meters of your victim periodically checking your signal strength to confirm you are on the right path. Learn about Avalanche Safety and ski epic POW!
What is the difference between a beacon and a transceiver?
The Difference Between a Transceiver and a PLB An avalanche transceiver is not the same as a Personal Locator Beacon (PLB), which can only be used to send an SOS signal to search and rescue teams; those teams are likely to be too far away to aid you in a successful avalanche rescue.
Is RECCO an RFID?
I am not very familiar with RECCO’s Avalanche system, but from what I gather from reading the company’s Web site, it is not an RFID system. It appears that the detector sends out a low-frequency (LF) signal—457 kHz—that can penetrate the snow. It reflects back a signal, but it does not send back a serial number.
