Catch radius

Setting	Catch radius (meters)
Rule parameter	catch.radiusMeters
Default	30 meters

The catch radius is the maximum GPS distance at which a catch attempt can succeed. For this the server compares the most recently reported locations of X and the detectives.

Which value should I choose?

GPS is not always exact

Buildings, trees and reception can affect the position measurement. A larger radius compensates for such fluctuations but makes catching easier.

• 30 meters is a practical starting value for most rounds.
• A smaller value demands more precise GPS measurements.
• With poor reception a larger value can avoid frustration caused by GPS deviations.

Choose the radius so that a catch also feels fair and comprehensible on site. With the photo catch, a detective reports the catch and X confirms it in the app; photos are not uploaded.
