Can we get more info? Velocity, dist from planetary body, inclination, maybe a pic for review? I thought along the same lines at first, but i found out it depends on a few things as to how frequent the tone is. Velocity, dist from the planetary body ur scanning, inclination etc. Here's my setup with Mechjeb for info. the basics: - Orbit: 245 000 km - Inclination: 88 degrees - Velocity: 300 to 400 ms - 1 med scanner & 4 sml scanners (basically can scan the surface no matter its orientation) My scanner is based on the concept of self sustaining vessel without need for continual watching. Others may have a better, more effective setup than me. Cyphas_Cain
