I now have two trips in using the link beacon and absolutely love it.
Arva did a great job making a beacon with all the bells and whistles that you could want but still keeping it very smile to operate.
My first time using it I kept it in novice mode while practicing multiple burials, it worked like a dream. My friends that had other brands also did well but some of them put their beacons in expert mode which made their beacons much more difficult to use.
I have since practiced in expert mode with multiple burials and I can't tell you how easy it was.
You use the two buttons on either side to toggle between which beacon you want to go after and the middle button to either mark or unmark, very simple. Compared to other beacons which ask and make you answer questions to toggle and unmark.
After using the same beacon for almost ten years the harness that arva uses is a much needed addition, I no longer have to figure out how my beacon get's worn.
The standby mode is super cool, especially if you do any teaching.
The w-link defininately makes a difference when searching for other beacons utilizing the same technology.
