2 questions. I just recieved my kestrel AB and I plugged in all the data correctly. For the dope I'm seeing I used the calculate MV and it put me at 2720. I have verified several times with my oehler that I'm right at 2800 with my 260 with a 142 sierra. So whats with the 80fps difference?
Next question do these not come programmed to tell wind speed? I was trying to get a wind speed and it said like 4mph when it was more around 15mph? Thanks
I see on the AB web site that a discount is offered for Veterans. But, when I try to check the boxes that way I get the same retail price. Is their a way for a Vet to get a better price? Thanks, Don.
when you were setting it up initially, and you had to remove the impeller, did you press on the center at all? The bearings are extremely delicate, and if you removed the impeller incorrectly you could have damaged it.
Does the impeller have to be removed at first to calibrate compass? I didn't and it seems fine. Other reason to remove?
Also, I know the manual says for the AB program will use station pressure yet the dope continually changes as you hold kestrel. So that makes me think it is gathering weather data from where I am standing? So am I getting info from where I stand or some station? Thanks.

In order to get an accurate reading, you must have air constantly moving over the sensors. That means moving the Kestrel back and forth through the air and then taking a reading. If you have ever seen a weather station, they are uniform over the whole world because the atmospheric readings vary greatly depending on many factors.
You want the atmospherics from where you are, as this is the first experience the bullet encounters on its way to the target. Use the station pressure function by setting the reference altitude to 0 feet.
Good luck and have fun!!
I'm having an issue with my AB kestrel. Every now and then when I go to turn it on it won't power up, I end up having to open the battery door then close it and then it will turn on. I have the shim installed between the batteries. It's kind of a pain cause anytime I have to due it I have to recalibrate the compass...any ideas?
What version software are you running? They might want to upgrade it to 4.8. Yes, Joe will be very helpful. If you have the bluetooth version, upgrading will be simple. If you do not, then you will have to send it in.
I have the blue tooth version and am running the 4.8 software. I'll give Joe a call this week. Thanks.
Okay. Sorry I was not more helpful. Good luck and let us know how it worked out. I bet you Joe will have it fixed short of 5 minutes, he is that good.
It's been a busy few months finishing this guy up: RAPTAR-M: Hands-On with Wilcox Raptar and Applied Ballistics Prototype Raptar-M - The Firearm Blog
Great to see the prototype is moving along ! Any new update on likely production timeline for the AB Raptar-M ! You know I am waiting anxiously...
Here's what we teach for best results...
1) Go to AB Mode --> Environment
2) Set Environment Update = On
3) Take the device by the lanyard and swing it around a few times... maybe for about 10 seconds
4) Set the Environment Update = Off
That's exposing the sensors to the ambient air for long enough for them to take accurate measurements. By locking down the temp, you're ensuring that solar loading or ground heating and radiation is now affecting the unit at all.
Typically, I'll do this once every hour or two while shooting. The environmentals just don't usually change that fast. You really have to watch the temp though based upon time of day. You want a good ambient temperature reading.
Now I'm confused..... USING the Kestrel at the Range......do I leave the ENVIRONMENT screen "update" parameter ON or OFF? Or do what you described above every few hours to UPDATE readings?
The REAL question I was going to ask here.... Looking at my USER SCREEN #1 which has WIND DIRECTION....I do NOT get a stable reading. Even when holding the unit upright and motionless. The reading will bounce back and forth through the 360 degree swing.
Like; 316 , 271 , 161 , 047 , 027, etc. Try to RE CALIBRATE the compass?
Appreciate the help here.
