I just bought the Alpha and the quickest update rate is 2.5 seconds. I set it for pointing dog and the third button across the top to tone (beep) the hand held will vibrate / beep when dog is on point. My complaint is that the volume is low for the beep....just saying.
Wonder why they would do a 2.5 second refresh on the alpha but not the astro. 2.5 seconds would be great.
I agree on the beeping being too quiet. I did find the different tones, but with it in a pocket, even the loudest tone is quieter than I would like. Today was very windy though, so on a calm day, maybe it will be good enough?
Sorry for the novel, but thought I would share this:
I got out yesterday and had a few experiences that really highlight where the astro shines. First off, it was the first time where wind affected the beeper collar. I was hunting with a buddy and his lab. Last time we hunted together, his dog picked up on what the beep meant, so I wanted to bring it along. When the stiff wind was pushing the noise towards us, it sounded like he was right in front of us, when he was actually a long way away. When working with the wind at our back, I shut it off. Once he was a little ways away, it was pointless.
Now onto the big ordeal that has me convinced I will never leave home without the astro. The birds didn't want to fly yesterday, which was sort of a shock. With the snow, the way we were working the wind, and the fact that they were freshly released, we thought they would hold tight, and then flush, but we were wrong. My dog got on the trail of a bird and starting tracking it. We were walking through some thick stuff, so I couldn't see him, but my buddy saw him heading north. By the time I got out of the crap I was in, he was almost 300 yards away. He wasn't moving very fast, so I just sort of watched him. We walked out another little section of marsh grass with my buddy's lab, and by the time that was over, I looked down and he was 600 yards away and still leaving. I hit the tone button on the e-collar to bring him back and he stopped for a while and started heading east......then west.....the east....then north again. He was stopping every once in a while, long enough to throw a point tone on the GPS. I knew at that point, he was lost. He started north again. I was yelling his name, but the wind was pretty strong, and he was up over a large ridge, in the woods. If I hadn't had the astro, I would have been a nervous wreck!
I did get nervous though when the communication with the collar was lost when he was almost 800 yards away. I rushed to the edge of the woods and got communication back. I started hitting the tone button to get him to stop as soon as the collar was lost. Now he was still over 700 yards away, but at least I could see him on the screen again. I got up on the ridge and the wind died down a little and I started calling his name. He must have heard me because he immediately starting working back, and very quickly I might add. Occasionally, he would start veering off, but I would call his name and he would adjust accordingly. Eventually, he found his way back.
Was a very scary situation for me, and without the astro, I don't know how it would have turned out. I was able to get to a good spot to yell based on the last known position reported.
