The tools I thinke that Hernando de Soto used as tools swords, rifles, guns, daggers, and armor. Hernando de Soto was a soldier so he had gear. He did not sail a boat or used a astrolabe but I am pretty sure he used a compass to get around. He was a general or a commander. He traveled from Florida to mississippi so he used a compass to know if he was going the right way . He also used any tools that conquistadores around the 1500, 1600 used.
