If he wants to save a few bucks, have him buy a used Tracker. I have 2 that have almost no use as they are extras. Between my husband and I we have 3 Trackers and 2 Peeps. He prefers the Peeps, I prefer the Trackers. Even though I practice and I know my beacon well, finding someone is not always that easy, so practice, practice, practice. At home, with the kids, at lunch on the hill, at work, where ever, when ever. It has to be fun. Because when you get to the real thing, you will know what has to be done and it will not be fun. Make handling your beacon second nature, like driving a car.
No, mine are not for sale, but I am considering the purchase of a new Tracker because they are so good. There are some awesome deals on BCA stuff now. The new Float 30 Avi Pack, new Beacon, shovel, probe, and some other goodies for like $800 to $900. I considered it, but it was after I already bought the Float 30 Avi Pack for $499. and I really do not need another probe or shovel.
Definitely go digital though and get some training.
