Underwater archaeology has advanced with the invention of scuba, allowing divers to collect artifacts more effectively. Sonar and lidar have further improved the accuracy of site readings, eliminating the need for divers to collect information themselves. Remote-controlled devices are now used with lidar and sonar. Underwater archaeology has greatly evolved since its introduction. They could only do so many things to try to collect artifacts without having a way to navigate underwater. They would try to collect artifacts with buckets, nets, and even hooks. This would not be very successful, though, and often complicates discovery of those artifacts. The first real advancement in the field of underwater archaeology was the invention of scuba. Scuba made it possible to send real people underwater to carefully extract these artifacts. The invention of scuba was the first underwater breathing apparatus. This made it possible to send divers under the water for longer periods of time to achieve a more in-depth research technique. The next advancements in underwater archaeology would be sonar and lidar. These made it possible to get a more accurate reading of a site, and you would not have to send actual people under the water to collect this information. Remote-controlled devices were often deployed to use lidar and sonar.
