More efficient and certainly more energy efficient than wielding a big knife or machete, a good pair of pruning sheers are invaluable in the type of jungle we have here. Vines, tendrils, Salacca Palms, brush, and small branches are easily cleared with these. Plus, there is very little chance of hurting yourself like you can with a blade.
When traveling through the jungle, as a backup plan, we put leaves upside down on the trail to mark it. The GPS is good for the general lay of the route, but the finer details are best laid out by clippings.
On the ridge route that we’ve been working on, the trail is very well defined at times, then just seems to vanish… leaving us to trail-blaze to find it again.
