Whether using True North with a declination or Magnetic North, the relationship between the DOF and WD will be the same as it is relative. Really the only issue you would have with using Magnetic is with Coriolis effects being slightly off. For example at 1000 yards, if you think you are pointing 0 degrees but are off by 21 degrees, you would incur around 0.03 mil difference in Vertical Coriolis. At 2000 yards this is around 0.07 mils. IMO unless shooting at really extended ranges, it is much easier to use Magnetic North and not worry about declination.
The real question then becomes if the VAR correction is taken into account in the ballistic computations of the Kestrel. It might not make a difference most of the time (maybe a lot in ELR) but for peace of mind it would be great to know that it has been taken into account in the displayed results of the device.

If in the weather mode you are using magnetic the ballistic calculation uses magnetic. If you change it to True the ballistic formula uses True.

Friends

I just discovered that Kestrel has Zoom classes to teach you how to use your device. I wish I had found this sooner. Sign up and learn at:

Enjoy!

    Save it where? It exists in two places. In the app, and on the Kestrel. Is it not saved simply by existing and being able to be used?

    If you use the Kestrel link to enter your data then in the upper right corner you will see three little squares. If you tap those it will show save profile.
    You must save profile before sending to the unit or nothing will change.

    The three little squares are located in the upper right hand corner of the Edit Profile screen.

    Is there still a way to update Direction of Fire and Wind Info for all Targets in a target list? With the latest update I can't seem to find it again....unless I just forgot where I was doing it before.

    When I press save, and I’m able to send the profile to the Kestrel and use it, I assume it is saved.
    Are you saying there is another screen with 3 squares I need to save profiles to?

    The other screen I was referring to was for the Kestrel/Hornady 5700 4DOF. I should of ask what unit you were using first. Sorry. The key is to save the profile each time before sending it to the unit. Hope it works out ok for you.

    I have always saved changes before sending a profile to the unit. The always get erased during an update.

    I would give Kestrel a call. I can't imagine why it would get erased. Best of luck. Sorry I couldn't be of more help.

    It hasn’t seemed to matter yet as they are deleted every single time I update. Current is 1.45. I can’t say for certain what the last one on the unit was, but I’d wager a guess it was the last one before 1.45.

    I've had my 5700 Elite with AB for a couple of years now, and have done at least 8 updates, and don't recall ever losing anything. For me, at least, if the profiles are on the Kestrel, on recent releases, it pulls them, updates the code, a pushes them back. On early releases, you had to have them stored in the app yourself, but that has not been the case for some time. Note, though, that right after it reboots when the fw is loaded, it is *NOT* yet done - if a few moments, it should push the profiles back, and if you play with it prior to both the app *and* the Kestrel saying "Done", you can interfere with the restore.

    With the risk of asking a stupid question:

    I have an AXMC with 3 barrels and one fixed scope. The 3 barrels have a slightly different POI so when I change barrel I slightly adjust from 0 for 2 of the 3 calibers (obviously one of the three as 0/0 on the scope) . Should I use "zero height" and "zero offset" in the "gundata" for the other to calibers that are not 0/0??

    YES, set up separate profiles and us the ZH and ZO to indicate the variance from dead center for the two not zeroed dead center - high and left hits are + number entries and low or right hits are - number entries.

    Thanks for quick response.

    So just to be 100% sure: If my .308 barrel is 0/0 and my 300 norma after barrel switch is +.5/-0.2 MILS (zerood) that is also the value I enter in the profile for the 300norma barrel? And the value the Kestrel then gives -for the 300Norma gun profile- (let's say 10Mil up for 1000meters) that is 10 MIL up from 0. Correct?

    First, there are no ballistic changes between 1.43 and 1.45, the changes impact non-ballistic meters, so upgrade is not required.
    Secondly, make sure you PIN is turned off.

    ballistics don't match AB App vs Kestrel 5700 elite with Custom drag models . Whet I set G7 BC Kestrel ballistics matches the AB application.

    I think this is due to different data on the servers Kestrel Ballistics and Applied ballistics
    Hi! Can you help me with this?

    There is only 1 bullet library and that is managed by Applied Ballistics. When you open the Kestrel app it connects to the AB library and checks if any new bullets have been added and if yes, asks if you want to download them.

    then why are there differences between AB App and Kestrel device in the calculations?

    I disagree with this. Calculations should be the same before truing rifle.
    I can't remember if you answered, did you try changing both to G7 to see if the data line up perfectly? This will prove the settings are the same.

    You 100% sure you’re inputs are identical?

    If both products need to be and can be trued to actuals( and they do) why do they need to match perfectly?
    Yes, I'm sure.

    When I input G7 BC output calculations are the same

    When I set CDM BC in Kestrel and AB Application, output calculations don't match each other.

    His point, and it's a fair one is the cdm is returning different dope, in the kestrel vs the AB app.

    The models are different, why?

    The G7 in both returns the same dope in both, so should the CDM, this is a problem with AB, they did the same a while back with hornady eldm140, and an update radically changed the CDM. No rev control of information, several revs later it changed back.

    AB and the kestrels are awesome, but this is an area of needed improvement.

    Hi Kestrel,

    I might be in error here but I thought I saw Kestrel and Magnetospeed merged which makes great sense and should mean great things going forward.

    I am a fan of both products.

    If this is true could the people on the Ballistic meter side shout over to the people in the T1000 Target indicator side and point them toward this thread....


    Please give us back the Rev 1, T1000

    Sorry if I am in error regards my assumptions will quickly delete if I am in error.
