What is Sakamoto doing holding those rods? On page 3 of chapter 9, Sakamoto is walking while holding two rods in his hands. What is he trying to accomplish doing that?
Sakamoto is holding the L-shaped dowsing rods, which are used to


  locate ground water, buried metals or ores, gemstones, oil, gravesites, and many other objects and materials.




The rods enable Sakamoto to:


physically locate the trap set up by Acchan and his gang
spiritually locate "points which require adjustment".
