The BCA DTS Tracker 3 is a very good advance in transceiver design. The device weighs only 170 grams and is very small and easy to carry. BCA’s goal was to make the tracker 3, tracker 4and tracker Sthe same size as a modern smartphone.
In search mode, it tells you if you have 1, 2 or multiple victims and whether they are in close proximity.
There is a button that you can push that gives you a 'big picture' of the search and allows you to review all signals received in the case of multiple burials, helping the user to direct a search if working with other rescuers.
When you let the button go it locks back on the closest victim. Once you get to the first victim, you can suppress this signal and you will then lock onto the next closest victim.
New features include BCA’s no-nonsense markings for multiple burials and a special Multi-Burial Button that can switch between or suppress any signal in any direction in a multi-burial situation.
The foundation on the BCA DTS Tracker 3 is still built around the original Tracker Technology which provides the industry’s fastest, most precise pinpointing and instantaneous real-time display.
Combine this with Tracker’s reputation for durability and reliability and you have the most functional beacon in the marketplace.
If skiers are caught out by an avalanche, their companions in the vicinity have their work cut out. They have to locate the victims and dig them out as quickly as possible. The chances of survival diminish rapidly after 13 minutes of burial in the snow. Using a transceiver can radically reduce search times, thus increasing the chances of a successful rescue.

The distance between the strongest signal and the transmitter is based on the way the two transceivers are positioned and the depth of the burial. This can possibly confuse signals if there in awkward positions and are known as spikes.
During deeper avalanche burials, the strongest signal is rarely directly above the victim. Transceivers with fewer than three antennas and some with three antennas will lead you to the strongest signal, which will be a point that is near but not directly above the victim.
When the transmitting and receiving beacons are on the surface of the snow, the receiving beacon will receive the strongest signal when it is directly above the transmitter. This is right regardless of the positioning of the two beacons and the number of antennas in the receiving transceiver because the transceivers are only a few inches from each other.
Simple Spike Testing
Put a transmitting beacon between your feet, pointing vertically. Note that this should not be an Ortovox 3+,S1+ or Zoom+ due to there orientation-based transmitting.
Set the transceiver you want to test on Search.
Hold the transceiver horizontally at the height of your chest but so you can still read the screen.
Slowly move the transceiver from about two feet from your body toward the centre of your body. Move it about two inches per beep. Keep the transceiver a consistent distance from the ground and avoid twisting it.
The distance on the transceiver that’s searching should decrease as it moves towards the centre of your body. Transceivers with less then three antennas will display the shortest distance when it is a foot or two away from the centre of your body and again when it is directly over the transmitting transceiver.
This test shows if your transceiver handles spikes at one meter.Spike handling is much more significant with deeper burials.
