Set the timer to 139 seconds

Online timer for 139 seconds

Starting the countdown for a second pass gives you 139 seconds to inspect the tent again for signs of a dingo. You may have checked the obvious spots already, so this round can cover paw prints near the entrance, disturbed soil beside the guy ropes, and any food scraps or rubbish left around the campsite. The short repeat also helps when fading light or dry ground made the first look uncertain.

Circling the tent again can take you beyond easy hearing range of a phone placed inside. A loud signal may still disappear beneath wind, conversation, a camp stove or vehicles arriving nearby, while an overly sharp tone can bother other campers. Keeping the device close enough to hear, with a moderate volume selected before the second circuit, makes the finish noticeable without turning it into a campsite-wide alarm.

Repeating the inspection gives you a chance to change your route rather than trace the same steps. Moving quietly in the opposite direction may reveal marks missed from the first angle, while the people nearby are less likely to be startled if they know a brief signal may sound. If someone is sleeping in the next tent, placing the phone in a pocket can keep the alert close to you and reduce how far it carries.
