Definitely don’t want to hoof it. Many use the srv to cover a decent amount of ground and start looking but I prefer getting back in my ship. I do this in a Dolphin so viewing and landing aren’t hard at all. Get in, lift, boost with 0 throttle, and end up plenty far as needed for diversity. But yes, it can be a real pain. For bacteria, I like to land somewhere near the terminator (day/night border) and fly towards the star on the horizon. It seems to help highlight the change in texture. But, still, I do give up entirely sometimes. Especially when I can’t find the 3rd bacteria hit come across some very visible fungi.
