I'm looking at a wind meter as well. Researched this a lot.

The Kestrels are certainly
much better quality with great customer service. I have a windmeter of
another brand, that connects to Strelok Pro via bluetooth. Nice, but....
It rarely works the way it is supposed to, it turns off after a short while by itself, and the air pressure readings were waaaay off.
For comparison look at the customer service of Kestrel: On the SnipersHide forum (not on a Kestrel forum) I asked specific questions that are relevant for airgunners wanting to use a Kestrel with the
Applied Ballistics package.
Within the day I had a detailed response from a Kestrel representative — and honest, as it was not favorable to what I wanted....
So, I still want a Kestrel. Without the PB ballistics program — they're not really made for airgunners — 25y minimum range, and other incompatibilities.
Strelok Pro is just amazing in comparison.
Now I need to decide: (1) Do I want my Kestrel to connect via bluetooth to my phone/ipad, even when a short distance away (10-30y), and continuously update my wind in my Strelok Pro reticle display?
(2) Or: Is is sufficient for me to read the wind velocity when holding the Kestrel into the wind, and then enter the wind manually into Strelok Pro?
Option (1) ends up very expensive: ▪Kestrel 4500
with bluetooth (cannot be added on later) = $180—250 used (discontinued; effective bluetooth range 10y)
▪OR Kestrel 5700
with bluetooth ("Link") = easily $400 used (effective bluetooth range 30y)
▪AND Weather vane = $50 new (rarely ever sold used)
▪AND Tripod to mount the weather vane = $30 cheap-o
➔ TOTAL = $260 to $480 (
used; for
new add another $100 to the 480).
Option (2) $100 gets you a used Kestrel that does all you need if you're fine with doing the handheld and manual entry thing.
I'm still struggling to decide.
I love the bluetooth thing, but is it worth an additional $160 (and a patient
Ebay search & wait of 6 months or more for a used unit at that price)...?

PS: Used Kestrels are often sold making ambiguous statements about their
bluetooth functionality. Do not be fooled!
If the 4500 does not have the bluetooth symbol on the top left of the screen — or —
If the 5700 does not have the word LINK written on the button located at the bottom right of the screen —
➔ then that unit
does not do bluetooth. And never will.
