So, put in that context, I'd rather have a piece of equipment with me with consumer grade electronics in it which MIGHT fail as part of an extending net to help find and avoid traffic than rely on just my eyes solely - after all, if it points out conflicting traffic which I've not seen, then it's done it's task......
Steve,
I agree with you. An interesting point about my club's experience, is that there is a lot of Mode C traffic in our airspace that we weren't previously spotting visually.
For the benefit of people not familiar with PowerFlarm, it gives range, azimuth, track direction and altitude differential of other PF and ADS-B equipped aircraft. For Mode C equipped aircraft, that are being interrogated by SSR, it shows an estimated range ring, based on the power of the received signal plus the altitude differential.
