seeing questions on forums, in our inbox, and over the phone about the
differences between some of the weather meters. All of the models have
slight variations. Some will do a lot of different things and some will
definitely help you more than lifting your wet finger in the air. Keep
in mind the weather meters aren't designed only for long-range shooting.
Some guys buy them for long-range shooting and other uses (hiking,
vocational use, etc.). Each newer model retains the features of the
previous model while adding some new features. Here's a breakdown:
Kestrel weather meter has a display with back lighting for low light
conditions. Each meter comes with a 5 year warranty.)
adds on a pressure sensor that helps you predict fish and wildlife
activity as well as knowing when the weather's going to turn nasty. This
is useful because barometric pressure influences a bullet's trajectory.
The 2500 also measures altitude and has a clock and calendar function.
K3500 Delta T -
incorporates a Delta T calculation. In layman's terms, a quick guide
for acceptable spraying conditions (ex: applying pesticides). While the
Delta T feature doesn't do much for a shooter, this model does have a
data hold feature that will record your data along with the time. The
3500 also comes with a lanyard and protective cover.
calculates Density altitude. It has a Data Storage feature where a user
can automatically store data at personalized intervals (you can set to
record data every 2 sec, every 12 hours, or anywhere in between. The
K4000 has an expanded button interface compared to older models. Data
can also be uploaded to a PC with the optional Kestrel Interface.
includes a digital compass, wind direction, crosswind, and
headwind/tailwind. Ideal for long range shooters and military snipers
NV - Night vision -
The back-light on night vision units is more subdued. It incorporates
an optical filter to reduce overall brightness and preserves night
vision. It takes 30-45 minutes for the average eye to adapt to darkness
and maximize night vision. Therefore, this is ideal for use once your
eyes have adapted to low light conditions., preventing night blindness
and night vision fatigue. The NV models come only in OD Green.
- wireless data transmission eliminates the need for a separate
interface and cabling. Data transmission communicates up to a 30 ft
As far as shooters are concerned, the 2500 is a stripped down version
that will still give a shooter the basics. The 4500 gives the shooter the most transferable info out of all the models.
