So I purchased this beacon early this year simply because it was cheap option to get me into the backcountry. I've been taking some avy/touring classes over the past month, and have came to the conclusion that it's terrible. Not speaking on Arva's technology it functions fine. However the design of this beacon has some possibly fatal flaws.
First, for the the beacon to be turned on it must be strapped to your chest with its built in harness.
(red key must be plugged in)

Sure this is a fool proof way to ensure that the beacon is always on and transmitting, whatever. The problem is, in a situation where you're searching for a buried victim its strapped to your chest. It's nearly impossible to get this thing level to the snow when bracketing for a victim.
The second flaw is the switch that toggles between search and send. The switch toggles so easily that in a rescue situation for example your partner is bracketing and you're probing or getting rescue gear out of a pack. The beacon can be switched from search to send with any slight bump, Throwing off your partners signal.
I haven't experienced this so its purely anecdotal, However I also believe that this switch could be toggled from send to search easily in the event of an accident. Leaving you buried without a signal. Much like Nick Mcnutts situation with the Peips beacon. (https://www.instagram.com/p/CHBU5imB18o/?utm_source=ig_embed&ig_rid=0f39b511-424c-472f-97b7-2b56ba2864d3)
Glad I found these flaws out while doing drills and not in any real situations.
TLDR: Don't purchase this product.
