I don't see any mention of the Sig 2400AB.....Someone bring me up to date on this please? Must be a reason it is not one of the suggested rangefinders?
Teesquare, the 2400 is another very robust solution to consider, but it does not give the EHR in the way that the OP requested. In many ways, it is superior, in others, not so much. It is very expensive, but includes AB software right there. Just range it, and it will spit out your solution right there in mils or MOA. No need for a turret. Holds 3 different curves, and AB sw is awesome. I have it on my Kestrel Elite (BTW, Leica's SW is older, but so far, out to 1k, it is within .1 MOA of the Kestrel, and with a little tweaking, the difference was only .05MOA when coriolis and/or aero jump were not factors). A lot of guys really like theirs, I have used one in a limited fashion, hope to score one for longer loan to review soon. Sig's RF's are really fast as well in terms of reshooting your distance etc.
Downsides to me at least, the most obvious will be the glass. To my eyes, not even close, but some people don't care about this. More technical, the Leica has a smaller beam dispersion, 50% IIRC. And then there is the wind solution. How you handle this will determine whether the differences matter or not, but the 2400, the wind seems kind of an after thought to me with the dongle they supplied for your phone. When I talked with the Sig engineers, they sorta agreed, but they said that when they use it, they just put in a generic 10mph wind and then adjust their hold based on where they thought it was in comparison to this number. Problem with this to my mind is 1) I really want to know a little more precisely what the wind is doing, probably due to my inexperience in judging the wind, especially when I travel to new places where the vegetation is different from home 2) I found entering the wind into the Sig fiddly with the buttons etc 3) Wind is an important calculation with Aero jump, so if you put in 5 but it's really 15, your aero jump will be wrong. At 500 yards, no biggie, but at 1500, can be a biggie.
For the cost of the 2400, you can more or less buy a 2700 and the Kestrel Elite with AB. Not suggesting that's the better solution, nor that the 2400 is the better solution. It just depends, they both have their strengths and failings, and both manufacturers have left something on the table instead of really finishing the job in my opinion.
Best solution, to my mind, and only on paper until we see how it performs, looks like it will be the new Vectronix....range...it talks to a Kestrel Elite where everything is automatically entered and your solution is right there, wind and all. But man, that is a pricey solution!
