dear garmin, i got a astro 220 with a dc 30 collar last year, it works great, but i would like to know will the new dc 40 collar work with the astro handheld gps that i got last year, and can i use the new pin number deal on the new dc 40 with my handheld unit that i have got now, thank you

Dear leon..
This is not Garmin. But you will be able to use the 220 you bought Last year with the DC40 collar.. (At least I’m about 99% sure) You’ll probably need to update the software to utilize the Pin feature and the 120 second update. But that is easy and free.
We offer free Tech support for all of our customers, Let us know when your ready for a DC40 and we’ll make sure to help guide you through any setup and Upgrading you’ll need to do..

i was wondering if 150 to 151. freq. telemetry collars affected performance on astro or its collars

I don’t believe there should be any performance effect on the Garmin. However I would contact Garmin to see what they say.
