Arva EVO4 Transceiver Search :
Coarse Search :
Moving the EVO4 from Send to Search is super easy, you pull up on the big red tab at the top of the beacon.
When receiving a signal the EVO4 will allow you to "coarse search" and keep you on the flux line very efficiently with audible tones and directional arrows.
Fine Search :
Once within 3 meters of the victim, your EVO4 no longer indicates a direction and you must start the fine search methods.
1. When fine searching with the EVO4 you should lower your device to near snow level. 2. Move your device in a cross pattern to locate the point where the distance reading is the lowest.
It will then be much quicker to start probing once you have defined the probable burial zone within a less than one-meter range.
Arva EVO4 Transceiver Multiple Burials :
The best feature of the EVO4 is its multiple burial function and more importantly the interface surrounding this function.
The new EVO4 features a simple marking function that uses a well designed display and is activated by a red flagging button.
When multiple signals are being received, the EVO4 has multiple burial victim icons displayed on the left side of the screen with 1, 2, or 3 people (victim) icons.
The distance to the next closest beacon is still displayed in the center of the screen. Once a victim has been marked (flagged) a little flag symbol will appear next to the victim icon.
