Why Handheld Kestrel Devices Don’t Cut It

Kestrel handheld WBGT devices have a bias for higher readings

Multiple independent studies have shown that Kestrel devices tend to provide readings that are higher than the actual WBGT. This becomes more pronounced as the WBGT values increase, resulting in activites being altered unnecessarily.

They can’t tell you what actions to take or warn coaches + training staff

Kestrel devices are simply a measurement device. They aren’t integrated with your heat stress policies, and they can’t tell trainers and staff what to do next. Perry Weather alerts all coaches and staff what to do next via text + mobile notifications.

They require maintenance and calibration

Kestrel devices require calibration for up to 30 minutes before use, leaving you with yet another thing to worry about before practice. Eliminate human errort and calibration issues with Perry Weather.
