Winter is just around the corner and we’ll be skinning for the goods not soon enough. If you are relatively new to the backcountry, are you familiar with what we consider standard maintenance and safety checks for your highly technical avalanche transceiver? These life-saving devices are critical equipment for every backcountry day and need thorough inspection pre-season, every year.
One of the most often overlooked details that lead to transceiver failure is leaving the batteries in the device over the long summer season or for extended periods without use. More often than not this leads to corrosion on the terminals and WILL cause malfunction. When you remove the batteries make sure the casing and terminals are clean and dry. Below is a list of suggested maintenance checks to keep your avalanche transceiver up to the task of its job.
- Inspect the battery terminals carefully. If there is any sign of corrosion, send the device back to the manufacturer for a complete inspection. Do not touch the terminals with bare fingers but do check with gloves that the terminals are not loose.
- Use high quality alkaline batteries. Never use rechargeable batteries. Some devices will work with lithium batteries if set to do so but unless you are going into extreme cold environments, it is recommended to stick to alkaline batteries. You will get about 200 hours of use with fresh alkaline batteries. A daily battery check is the first thing you do when you turn your device on and if yours indicates they are 40-50% or less, replace them or follow the manufacturer’s recommendation. Carrying a spare set in your pack is good insurance and often you’ll end up giving them to a partner to use. Don’t mix brands and always renew all of the batteries at the same.
- Follow the manufacturer’s suggestions for inspections, life-span and use. This varies considerably. Mammut recommends sending their Pulse in for a factory inspection every three years and their Opto 3000 every two, with regular practice sessions to check for any erratic behavior. BCA recommends thorough and regular inspection but does not specifically recommend sending it in for checks. Knowing what the recommendation is from the manufacturer of your beacon is important and following it could save a life. Be sure to check the harness system and casing of the device for any problems.
- This is all over the board with many manufacturers not specifying a lifespan for their device, to others such as Pieps recommending that 10 years is the maximum lifespan. Again, follow the manufacturer’s recommendation and retire any beacon that is malfunctioning or displaying erratic behavior. Retire it as a practice beacon and practice regularly.
- Check the transceiver’s signal acquisition and transmit function and range. The manufacturer of your device has recommendations on how to do this and there are many good resources online.
- Check all the device’s display and buttons to insure they work correctly.
All of these checks should be done at the beginning of every season before your first day out and if there is any question about a device’s integrity, consult the manufacturer right away. You may need to replace your device, which is a small investment in longevity.
Be sure to guard your device against impacts and drops. The antennas are fragile. If burying it for practice, it’s a good idea to protect it in a pack with tupperware or something that a shovel won’t damage.
