Finger Clock

This hack isn’t so much about finding direction as it is knowing when to stop hiking and start making base camp for the night. Many survivors underestimate how long it can take to set up a proper base camp, and then find themselves rushing around in low-light conditions. A reliable way of estimating the amount of time left until sunset is by using your fingers. Hold your hand up sideways with the bottom of the sun resting on top of your index finger. Now, count the number of fingers going down until they connect with land. Each finger represents approximately fifteen minutes of sunlight available.
