Products Ultralight Backpack Mounting Equipment

The calculator below will generate a "ball park" measurement for installing our Ultralight Backpack on your hawk.

The calculator relies on both empirical and theoretical data. In some cases, there simply aren't any data available so we use linear regression to predict the results. We use models to predict the measurements for species that don't have empirical data. In order to get better results, we break the prediction model into three distinct categories of birds: micro, medium, and large.

If you find this program useful, please help us make it even better by submitting your final installed data (species, sex, weight, and measurement) or any previous data so we can improve it for the falconry community. Please email data to:

  physical build may be different and you may need to make minor
  adjustments for it.

These measurements are from the tip of the Ultralight Backpack to the cross stitch location, which is just below to crop.
