Re: Gunwerks G7 BR2 Rangefinder Review

Also, how do you enter wind direction? is it a clock, degrees or 1/4 , 1/2 , 3/4 and full value?

Thanks
Jeff

I think you have to guesstimate. If the wind is say 9mph but coming in at a 45deg angle then you would enter 5mph wind.

You don't enter a direction all wind increments are for a full value wind.

This sounds like it would be something that would take more practice than a ballistic program with the clock system and finer mph increments. But I feel with a lot of practice a faily accurate level could be achieved. But for sure a lot of guestmating. 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!!!

Re: Gunwerks G7 BR2 Rangefinder Review

I hope I am not asking too many questions or ones that have been covered here before. But this info could be good for the thread as well.

So, Does it accept G1 and G7 BC's ?

Also can you enter multipul BC's and low end velocities?

Thanks again

Jeff

Broz,

It takes G1 and G7 BC's. Not sure about the multiple BC's but it has the trajectory validation tool witch will fix error in your trajectory curve.

Also, regarding the wind questions you asked above. For traditional LR shooters that are used to using ballistic charts or programs and wind meters etc, the G7 concept does seem quite different at first and even less precise but the G7 boys have done a nice job in coming up with easy ways to determine cross wind component inputs from a full value wind.

This video gives a short explanation of how they do it. I have played with their concept and it works well with some practice. For me there is a lot of going by feel and experience anyway when it comes to wind doping because there are so many additional factors that a wind meter can't show so in many ways I am coming up with my own wind input anyway based on up/down drafts, cross currents, etc. I think with some time in the field the 5 MPH increments would become pretty workable.



HTH,

Scot E.

Thanks Scott, I would assume the trjectory validation does it by changing muzzle velocity up or down. Or does it have a way to alter BC and velocity to better fine tune the curve? I would think that would equire entering multipul distances at once for validation. Is that an option?

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.
