We currently only have a mount that works on a Picatinny rail (which is included). We are currently looking for partners to help develop different mounting options for customers who do not have Picatinny rail mounts. Hopefully this could be an option at some point in the future

Please make sure to turn off either the Kestrel or the HUD after using them. While both have an Auto Shutdown mode (when enabled), neither unit will turn off when connected to each other. Therefore if you throw a connected Kestrel and HUD into your bag when finished shooting, neither will turn off until the battery dies (or you eventually turn them off).

When filter is on, it runs the microphone through an electrical filter, but as of now we do not recommend turning the filter on as there should be no need to do so.

Please see the attached guidance with Exporting Issues with LiNK iOS.

Your KST1000 can be configured for fixed or random start delays in the main menu. With the left and right buttons, you can scroll the fixed start delay. Scroll all the way left to turn off the fixed delay. The random line allows you to add random time to the start delay. Again, scroll right and left to change the maximum randomized time. This combination of fixed and random delay will result in a random delay between 2.0 and 3.0 seconds. To change the lower bound, make the adjustment in the start delay line. To change the upper bound, make the adjustment in the random line.

1. After calibrating the compass, use the left or right arrow buttons to set the range. Holding the button will make the range increase quicker.
2. Press the center button to enter environmental capture. Swing or wave the Kestrel to get airflow over the sensor. Once the temperature stabilizes press the center button again.
3. Next is the direction of fire screen. Point the back of the Kestrel towards your target and press the center button to do a capture.
4. Wind direction and speed follows. Point the back of the Kestrel directly into the prevailing wind. Make sure you capture at least 10 seconds of wind in this direction and when satisfied press the center button to end capture.
5. If inclination was set in the app, enter your inclination angle using the directional arrows.

See chart below:

Set the logging rate to the max, 12 hours. You could set the data refresh rate to its max, 1 minute, but that will only have an effect when connected to the DROP. Also if you connect to the DROP in colder weather, this will affect battery life more than in warmer temperatures. If possible, warm up the DROP before doing a data upload to Kestrel LiNK to help with battery life.
