I have not used the Sportdog track and train but. Have been using the Garmin/Tritonics for about 10 years. Upgraded from the Astro to the Alpha 100 when it came out. The newest equipment is even lighter which my hunting partner owns. Out here in the Southwest it's as important as my shotgun, simply will not go out with the dogs without it. I only use a few features as it has everything most GPS handhelds have today. Like Gary I use about 4 main features. I like to track my dogs, get alerts when they go on point. My pointers usually are ranging 150 to 200 yards up the canyons, and with my hearing I cannt hear a bell further than a few yards. I like to know where the truck is, mark a few waypoints, and if your hunting partner has a unit you know where he is. Best money I have spent. These units are weather proof and can take a lot of abuse.
