Yes, I know there is a huge thread about this already so before anyone post "go read it," I have. Its a lot of "You should add this" or "change that." What I would like to know is how accurate it is, specifically the density altitude feature. I cant find any reviews about it online. What I am wondering is if it works very well, do I need to spend the extra money on a Kestrel 4500 that does the same stuff. The only extra feature the higher priced Kestrels have over the lesser models is the density altitude, and I cant justify spending the extra $200-$300 on something that the Shooter App does already.
