Two key developments that made exploration voyages possible were advances in navigation technology and improvements in ship design. The invention of the magnetic compass and the astrolabe enhanced sailors' ability to determine their position at sea, while the development of sturdier ships, such as caravels, allowed for longer and safer journeys across oceans. These innovations enabled explorers to venture further and map uncharted territories, leading to significant discoveries during the Age of Exploration.
There are quite a few devices that have made sea exploration as you know it possible. Submarines are one of these devices.
