I just had the pleasure of using my Kestrel 4500NV with Applied Ballistics for a local Long Range Varmint Silhouette Match on Saturday. I have the bluetooth model and I downloaded one of the custom bullet drag curves the week before.
It was DEAD ON at ANY range. I was completely blown away. No more having to send data to a PDA or having to making guess adjustments for the change in temperature throughout the day. I simply looked at the Kestrel and it was bang on the Varmint silhouettes out to 850 yards (800 meters). The wind meter function, giving you wind speeds 1 and 2 (denoted as WS1 and WS2) and the direction, gave me a lot of information. Hitting the rabbit at 500 meters was not a daunting of a task as it was before the Kestrel.
I just cannot say enough good things about the Kestrel. Thank you LawnMM for your help and thank you Bisontactical.com for the 5% discount. I am not for shameless plugs, but damn, that Kestrel kicks ass. Okay, back in my hole now.
