Rap on analog vs. digitalbeacons

Back in the old-days, all beacons were analog, but with the rise of computer technology, most manufacturers use computer chips to filter, process and display the signal, which makes finding a buried beacon faster, simpler and more idiot-proof. You can now find a continuum between all-analog and all-digital beacons with a variety of combinations in between. Contrary to popular belief, the so-called "digital" beacons still use an analog signal like the other beacons, but they simply use a microprocessor to filter, compute and display the signal. And finally, digital does not necessarily mean better in all cases. For instance, some professional avalanche teams still use all-analog beacons because they tend to have a longer range and the analog audio can be an advantage in multiple burials. But especially for the casual user and people who don’t practice very often with their beacons, the digital technology has made beacon searches simpler, easier and faster.

The technology of beacons changes so rapidly that anything we say here would be quickly out of date, so be sure to read the latest reviews of beacons in the magazines and web sites. Talk to the salespeople in the stores and be sure to shop around and play with several different models. There is no “best” beacon on the market, just advantages and disadvantages with each brand and model.

Practice, Practice, Practice
No matter what beacon you buy, the most important step is to practice, practice, practice. Remember that finding a single beacon in a parking lot is far easier than finding multiple buried beacons in a realistic situation, especially when a loved one is under the snow. Many mountain locations now have automated or semi automated beacon trained centers. These allow one to practice both single or multiple victim rescues, solo or as a group. Check with your local Avalanche Forecast Center for a beacon training facility near you.
