Free: Contests & Raffles.
If your hunting partners have Garmin Rinos, get one. My 655T has a 5 watt radio, texts between established friends, locks on to satellites super fast, pins yours and your partners' locations on the map, synchs up with a desktop program and your phone, has routing, and makes fried bologna sandwiches for you at lunchtime. If you want a handheld that plays well with others, a Rino is excellent.
