Kestrel Instruments Support & FAQs

Reference Altitude and Reference Baro have no impact on your ballistic solutions when using the Kestrel's internal solver.

If you are using an outside application to solve for the ballistic solution, it is suggested that you leave REF ALT set to 0. If you can select Absolute (or Station) Pressure in the app, then just use the number on the Baro screen wherever you go. If your ballistic solver expects an altitude, use the number on the Baro screen and always input 0 as your altitude. This way your solutions will be right and you never need to adjust the Kestrel at different locations.
