K2 BCA Tracker3 review

The thinnest multi-antenna unit here, and the only new one that publishes its frequency, its size and its weight.

The bottom line The best-documented new transceiver on the shelf, missing the one figure that describes a search.

What it publishes

  • 457 kHz — the frequency
  • 11.5 × 7.1 × 2.4 cm — the dimensions
  • 215 g — the weight
  • Strap and AAA batteries included
  • Described as pocket-friendly and the thinnest multi-antenna transceiver

Five real lines. On this shelf that is the most any new device offers.

The 2.4 cm

The maker’s claim is thinness, and the dimension is there to be checked. A transceiver is worn against the body under a jacket all day, and thickness is what decides whether it is worn there or left in a rucksack — where it is of no use to anyone.

What is missing

The search strip width, which is the figure that says how fast a slope can be swept, and the battery life, which says how long the device transmits.

The used PIEPS on this shelf publishes both. No new device here does.

What this page stops short of

Nothing here makes a slope safe. The device shortens a search and the numbers above describe the device, not an outcome.

The price across six stores

323.43 in Britain. 349.95 in the United States. 369.64 in France. 375.46 in Germany. 385.05 in Spain. 388.32 in Italy.

Availability

One check, 370 € at the bottom and 388 € at the top, across the German, French, Italian and Spanish Amazon shops.

Outside the euro, the American and British Amazon shops sell it in their own currencies, and the range above is kept clear of that.

The declared figures, and where they run out

Strengths

  • Publishes the frequency — 457 kHz — the dimensions and the weight, which no other new unit here does
  • The harness and the batteries are stated to be in the box
  • Described as the thinnest multi-antenna transceiver, and the dimensions back the claim up with 2.4 cm

Compromises

  • No search strip width and no battery life, on a device whose two jobs are transmitting for hours and being found quickly
  • The Italian price, 388.32 €, is 65 € above the British one
  • Nothing about a service interval

The two closest on price

Same category, nearest budget — what else the same money buys.

Questions asked about this one

What is 457 kHz?

The frequency every avalanche transceiver in the world transmits and receives on, so that any device can find any other. The used PIEPS on this shelf names the standard behind it, EN 300718; this listing gives the frequency without the standard.

How does it differ from the Tracker S here?

The Tracker S listing says what it lacks: motion sensing and upgradeable software. This listing does not confirm that this one has them. What it does publish — frequency, dimensions, weight, contents — the Tracker S listing does not.

Are the batteries really included?

The listing says so: strap and AAA batteries are in the box. On a device that lives in a rucksack for a season, the battery type is worth knowing anyway — alkaline AAA is what almost every transceiver uses, and rechargeables are usually discouraged.

Who this one is for

A skier who wants the full Tracker with the features the Tracker S leaves out

If this one is not the right fit

  • On a tighter budget: BCA 23H2000.1.1.1SIZ, at 287 $ in the same category. see the review
