This is a great kit for anyone. The beacon is incredibly simple and intuitive. A child could pull the tab and find another beacon! The harness that comes with the Tracker 2 is perfect and very easy to customize. I can't think of anything negative about the beacon.
The shovel is great, but at times I wish it was slightly larger. The shaft doesn't extend, and the blade has a fairly small surface area. It's very light and compact! Having used other shovels, I still prefer this one because it's wicked burly, lightweight, and fits great in my pack. If you love digging holes, you might want to consider a blade that displaces more snow.
The probe is perhaps my favorite part about this kit. It is unbelievably lightweight and deploys easy. Other probes have a cord you have to clip into a notch at the end, which takes a little longer and feels less secure. This carbon probe clicks into place and you don't get the feeling it's going to break. It has a coated steel cable running through it so it'll last for years! Take my word for it, if you try this probe I guarantee you'll keep it.
Great kit for the beginner and the pro.
