I owned a Tracker Maxima for 4years and run five collars . Im a mad keen kiwi pighunter hunting every weekend and two or three times in the summer
, I learnt how to use the tracker maxima very well
And was happy with it .
Sitting around in the bush or back at the ute after the hunt telling stories we would often say it would be unreal if we could have
GPS tracking gear. Our dream has arrived with the
ASTRO 
As soon as it was out i was very Happy
to sell my Tracker Maxima which had saved me many hours of time looking for lost dogs
The Tracker Maxima found my dogs when lost ! Got me to pigs that i would of never found with out radio tracking gear
I could not believe it
I sold Tracker Maxima and was able to buy the Astro and four DC20 collars and still had a $100 in my back pocket for being a guinea pig
Having the LCD screen on the Astro with the tropigraphical map of your hunting area is hard to beat , I have been running the DC 20 with a whip antenna under the necks of my dogs and have had them water proofed
THANKS to the Astro Im getting to the pigs a lot
FASTER than ever before and have so much more info on each dog and where they are and what they are doing then ever before. The Astro has changed my hunting for the
BETTER 
My FRUSTATION is with Garmin and the change of release dates
and the bundle being released first .
I believe the hunters that have been running the DC20 collars would of been the ones to put the DC30 to a true test and could give Garmin {the liars that they are} good or bad feed back on the DC30.
I believe the knockers of the GPS tracking gear are living in the stone age
Get the cobwebs out of your pockets GPS is here to stay and will only get better
