The Arva Axio is easily one of the most capable beacons in our review, particularly in complex multiple burial situations. The Axio's extra long fold-out third antenna helps differentiate between signals in close proximity burials and the ability to toggle through victims along with an analog feature lets the user micro-strip search when the going really gets tough. Overall, the Axio was one of the toughest beacons to confuse and it miss-marked/miss flagged a beacon the least along with our Editors' Choice winner, the Mammut Barryvox S.
This model offers many different settings in each of its function to really let a professional cater this beacon to their needs. The one thing to keep in mind for more novice users is that this model's directional arrows disappear at 3 meters instead of 2 meters, which tends to be more a problem for them, but more practiced users had little trouble with it. Overall, this beacon is an improvement in every way over the older Arva Pro W.
