GPS Antenna
My GPS rcvr provides much better performance (much faster) when doing a replan with the external antenna. I don't keep getting a "turn-around when possible" command as I used to get when I missed a turn, etc. before I installed the external antenna.

Really Makes A Difference
Easy to install, built very well, and pulls in sigals even under the worst weather and or enviromental conditions. Well worth the price.

It is a GPS antenna - Not a TMC antenna!
Gilsson GPS antennas are the best on the market today. This is the first generation antenna and it still sets the standard for after market GPS antennas. Gilsson 3rd generation GPS antennas have higher performance and are a better value but are extremely hard to find.

PHOTO DECEIVING NO RECEIVER ONLY COLLAR
CAREFULL PHOTO IS DECEIVING & HAS BEEN REPORTED TO BE REMOVED
YOU WILL RECEIVE PART OF THE ITEM DESCRIBED & PICTURED YOU MUST HAVE YOUR OWN ORIGINAL DC-30 RECEIVER TO USE WITH THIS COLLAR.

CAREFUL - NOT A TRANSMITTER
With the DC 30 Garmin has fixed the bugs in their original astro collar. You had two choices on the astro - either screw a plate behind the transmitter and sandwich your dog's normal collar or else use this big velcro harness to wrap around your dog. Velcro + dog hair = useless fast.

Garmin fixed the problems - they put a metal plate behiind the transmitter and a separate gps antenna inside the collar up top pointing at the satellites. This is because the dog collar w/ gps naturally hung down due to the gps weight causing the old astro gps to point the antenna at the ground - it worked, just not as good.

THIS ITEM IS NOT A REPLACEMENT FOR YOUR ORIGINAL TRANSMITTER. The DC-30 is a fully functioning replacement, but this item is an accessory for the DC-30, mainly a replacement dog collar with mounting points for a gps antenna and a gps transmitter and an integrated vhf whip antenna. It is missing the GPS unit itself. That unit (including a collar) sells for 0-0 and is complete with chargers, etc.

This is just a collar. In fact, it doesnt even have a d-ring for you to put a leash on it. It is only meant to hold the garmin gps. You would buy this if your dog turned your old collar (dc-30) into a chew-toy and destroyed it or broke the antenna running through the field.

It's nice of garmin to make an accessory like this so you don't have to fork out another 0 for a dc-30 because your dog likes to chew on things or gets excited in the field. If you are looking to upgrade to the DC-30 this is not what you want - check for the 0-9 price package. It gets confusing but this is not a great deal on a dc-30
