I own a Barryvox. I'd recommend them to anyone expert or novice at transceiver use. It's very intuitive and is both digital and analog. As with any transceiver, the key is to practice lots with whatever you get, there are a few different good transceivers out there...
one thing to keep in mind (although very secondary to safety related features) Is what type of batteries does it use? AA or AAA or something else. It's nice to have your equipment work on the same batteries so you can switch them over if need be)

The Barryvox Transceiver, now distributed by Mammut, was introduced in the US a few years ago and has been a huge hit with backcountry enthusiasts of all abilities. It is a giant leap forward in transceiver technology offering both analog and digital search modes and the ability to switch back and forth between the two. A stream of range and directional data appears on an easy to interpret digital display, guiding the user along an induction line to the buried victim. There is no need for manual adjustment as you approach the victim. Simple one touch button operation is intuitive and easy to use—even for the uninitiated. Runs on 3 AAA batteries for a minimum 200 hrs. transmission time. It comes with THE most comfortable and best designed harness system we’ve ever seen.
