Thanks for the video, it is a good one, even though I was aware of these methods. I have had mixed results with the aiming of the wind meter in target direction. But that could easily been from a varying wind speed too. As you mentioned there is a lot of field time required to be able to read wind effectivly. About the time you think you have it whipped it will kick your butt.

LOL! Ya, the wind sucks!

You can use either BC or velocity to adjust the trajectory curve. Check out the Ballistic calculator on LRH. It is exactly what is used in the G7 rangefinder.
Long Range Hunting Ballistics Calculator

I believe they have you shoot at your maximum range, or as close to it as you can, and then enter the trajectory validation info from that distance. Then it will adjust the entire curve.

That is what exbal does out to 999 yards. But you can enter multipul distances with their own correction + or - in inches. Then it averages, adjusts MV and you get the best average curve. BC changes have to be done seperatly and manually entered. Exball will accept multipl BC's to which I have found a handy thing to get a perfect curve. The G7 only gives corrections to 1400 so it is pretty possible one BC would be good to go. Usually when only one correcton is done at the longest distance you shoot, it will result in the curve being off at 500 yards or so. But, It is much better to be off 1/2 moa at 500 than at 1000.

Probaby not nearly as big of a challenge for an advanced long range hunter, but for the moderatly experienced hunter that does not shoot all the time it could be an issue. I will mull this over and then discuss it with my friend. I was about ready to pull the trigger too, but now I am undecided again. Maybe I think to much...

I hate wind!!!

I think your always guestamaing the wind, to a certian extent anways( or we would never be wrong). As for the comment about moderatly hunter having problems with the wind system, he will have problems with any wind system(all were doing is entering numbers into a preferred system) jmo.. Reading the wind is the hard part, using the different calculators are the easy part..Biggest thing is pratice with any system, or you shouldn't be shooting at long distances.. I hope i make sense ..

I also hate the wind

I think im going give one a try.. Thx for the reviews from every one..

Like several members here, I am seriously considering this unit, along with the vectronix plrf05. The vectronix is being offered on a group buy over on snipershide. Davidsons, would you consider a group buy for LRH members?

i tried to find the price of the group buy vectronix at sniper hide..
Found nothing ..if you know ,,what was the price.
