5 days agoI can’t use any magnifying lenses because I have blind spots that interfere with it. I can use a digital camera, I actually have a pretty good one with 40x optical zoom. But since you need to really know where you’re pointing at for long distances, I mostly just use it for bee spotting!
The parabolic microphone idea sounds interesting! I use the Merlin bird ID app to identify what I can hear, but it’s not directional, obviously. I do have a pretty decent digital camera with 40x optical zoom, but you really need to know where to point it, because the slightest change in angle is a big change at a distance.
