I have done alot of looking but can't seem to find the answer. I have a older Kestrel NV4500 that I use wind and conditions and use Strelok for ballistics. I'm not sure how to set the barometric pressure and altitude. When I check it on Strelok the baro is close but alt.feet is way different. I'm really not sure what to do. I shot a comp that goes to a mile last year and I guess got lucky and made 2 impacts, but I really want to get this figured out. Thanks for any help as I'm lost as last year's Easter egg.
