The center of the beam in my unit is about .5 mils right of the center of the reticle and perhaps .2 or so high. I have marked the spot in the below image. I have slipped a little hand drawn diagram of this into the rangefinder pouch in case I forget. Fortunately, the Vector's reticle has fine graduations so it is easy to keep the correct spot precisely identified. I expect that this degree of deviation is probably well within the tolerances that most rangefinder makers accept in QC.

The short answer is yes, but you have a lot more choices than that. In the binoculars, unconnected to the app, your choices are to utilize the binos sensor or to input a temperature manually. This is very fast to do between the OLED screen and the full D-pad menu interface. If you are connected to the app, you can pull up the below environment screen which will populate with GPS determined local weather measurement data in the upper box and your choices for what is used in the calculation below. In this case you can choose device (this is the binos onboard sensor), internet for local weather station based data, or you can manually input the data. As you can see, this screen shot was taken when I was testing how much effect you could get on temp data from the binos sitting in the sun. It is what you would expect and your probably best off using weather station data for your calculations most times you have cell signal. The pressure sensor in the binos seems to generally be in pretty good agreement with local weather stations but the temp sensor will heat up a good bit when the binos are sitting in the sun and I do not belive the humidity sensor is super accurate. I was standing on top a dam 50 feet from a massive reservour at the time of this measurement. I don't think 23% was correct for the humidity. It certainly didn't feel like 23%.
