from the above link "Kestrel Elite Weather Meter with Applied Ballistics" [ not with LiNK ] - the pictures actually say "no link".
That is actually higher than my price. You really should be buying from someone you can talk to about these. That one your referencing is the Kestrel 5700 Elite with Applied Ballistics (no LiNK). Normal price on that is $599. I strongly recommend you buy one with LiNK otherwise updating firmware, or working with any of the tons of newly integrated devices like SIG, Leica etc won't work...
Guys like myself and most of the retailers here are giving Snipers Hide guys the best deals we can, and places like EBAY, Amazon and Devor arent going to give you a better price - and certainly won't take the time to make sure the purchase you make is going to do a good job for the type of shooting you are doing.
