Garmin Astro 220 price - as often as every five seconds, your dog's DC 40 transmits his position to your handheld , and you can see his current location and a trail of where he's been on the Map page of your handheld. Switching to the Dog Tracker page to view a compass pointing to the location of the dog as well as his current status : whether he's running , sitting , on point or treeing quarry. Astro can also sound an alarm to let you know instantly when your dog goes on point .
My dog does great off-leash 95% of the time. But if you chase something and I miss it , she will not stop until exhaustion , and then can not find his way home ( northern mix breed ) . Yesterday he chased a coyote in the desert snow. I traced for miles , of which over a 7000ft peak . When I found he could barely walk , and was disoriented. If it were not for this GPS, you would certainly have been a meal for a pack of coyotes.
There have been a couple of times during the research that the collar loses GPS reception (it was a forest area ) . But the receiver will continue to guide you to the last known position , and then updates once the connection is made again. So, if your dog is moving, upgrading , if not, you will know where he / she is. Given the mountainous terrain and forest cover that we may walk in , I'm surprised how well this GPS ago.
The collar is too big for my neck of the dog 50 pounds, so I bought a lightweight backpack for her. I put the collar on one side , with the antenna sticking out, and a counterweight in the pocket opposite side.
I was expecting difficult task , but mostly just press the " dog " - which shows an arrow indicating the direction of the dog, along with the number of feet or meters for the position. Pretty simple . There are many more features, but that was the life saver for us.
One feature I 'd like to see : a warning when the dog leaves a certain radius of the receiver. You could actually have this ability , but if so I have not found it yet.
