School me on Kestrel Units

[Dobermann]

What about other brands of wind meters? Are Kestrel the best option?

The system might work, but there is ZERO chance I’m using that contraption for anything.

I have this weatherflow meter and I can't get shooter to pull density altitude for some reason. It will pull density altitude in the BallisticsARC app.

Anyone have one and know how to do this?

I bought mine years ago and found it in my safe recently. I have been trying to figure out how it works but it is less than ideal. I just need to buy a Kestrel.

I looked into that a little. Does it plug into a phone or connect blue tooth?

It's Bluetooth

Here’s a DA chart-

I will post a video in a bit of how to use it.

Very useful. Thank you for sharing.

So if all you want is wind speed, DA and temp on the same page...which model Kestrel is minimum? It seems the cheaper Kestrels do not spit out DA, but instead station pressure/temp/elevation and may not have options for user pages.

That's great! I follow all that fine. Thanks!

I don't understand how fluctuations in barometric pressure are handled though. Do you just ignore it?

That's why I use temp and station pressure. Station pressure is combination of altitude and barometric pressure or as you put it, what the bullet "feels." I don't see how that's taken into account in your method. Does it just not matter that much? Thanks again.

First of all, thanks @Formidilosus for educating all of us. I definitely see the value in a simple single input instead of multiple.

I'm still hung on on the same question @Antares had. What the bullet "feels" is the resistance it is encountering in flight, which you are encapsulating in the single DA. From my beginner understanding based on kestrel's explanation of DA here, the DA varies with temp and station pressure. Alternatively you can derive station pressure from altitude and barometric pressure (i.e. corrected pressure).

In your estimate of DA in post #21, you were guessing temp and altitude to come up with DA. Assuming your temp and altitude are perfectly correct, couldn't there still be variance in how altitude estimates the station pressure? If so, that would lead to variance in measured DA vs estimated DA. Is this something that you've found doesn't materially change ballistic solutions enough to use in the field?

Or if you don't want/need a ballistics solver on board or bluetooth, the non link 5000 is ~250 bucks. Believe its the minimum model you can do a user screen with DA, temp, and wind.

 

[Shraggs]

When I bought last year, according to kestrel customer service the base 5700 was the starting model to include DA. This is without any on board ballistics solvers. I believe there are 4 5700 variants.

Regarding the 5000, things may have changed and would just call them as maybe it’s less money.

Pressure is mostly controlled by actual altitude and temp. Any error isn’t enough to cause issues in shooting. Start checking DA against your drops.

Do you scroll through the options you have selected or do they all show on one screen when getting readings?

Man. I wish I had known this earlier. Love the simplicity

If I'm understanding this the suggestion is pretty much to use a Kestrel for the wind and then a DA chart/basic math/shortcuts for everything else?

If that's the case is there anything wrong with the 1000 or 2000? Or even the Caldwell wind wizard which is like $36 on sale right now?

I don't shoot comps and right now am only shooting to 400 yards or so anyways. I'd like to push further eventually but for now 400 gives me something to work with. When hunting I typically have dope on my phone lock screen and printed out. I'm just looking for something to confirm a wind speed in hopes of improving my wind calls. Currently working on the brackets/mph system.

For my part it’s just an acknowledgment of what you need/what system is easier or better. I prefer a weather meter that gives me wind speed and DA as it’s quicker. The chart for DA is a great back up field tool.

As for weather meters the one I really preferred was the Brunton ADC Pro as it did both wind speed and DA, but also a clock and an alarm and the battery lasted a year plus constant on. They had some QC issues and were discontinued however.
