From Yahoo!: Garmin - released the Astro Dog Tracking System (pictured). Designed first for hunters, this handheld GPS unit combined with a dog collar that has a 5-inch antenna allows dog owners to track their dogs' whereabouts and what they're doing while there: sitting, barking up a tree...you get the idea. True, it's for hunters, but I can see some serious dog lovers who worry about their furry ones' safety putting this thing on when they're outside, even if they have invisible fences. It's expected to be available in June 2007 and it will sell for about $649. Subject: [Az-Geocaching] Garmin Astro 220 Now this is cool! http://www.garmin.com/astro/ It transmits position updates every 5 seconds on a VHF frequency. Could this mean that Garmin will make the Rino units available in VHF frequencies on the next model update? I hope so! The Astro 220 appears to have a better antenna on it than the Rino 530/520 as well. I still would like to see an external antenna adapter available on the next Rino Garmin puts out. The Astro 220 looks to be available in June of 2007. Another very cool and innovative GPS/radio integration by Garmin! Scott Team Ropingthewind
