I'm seriously considering buying a PowerFlarm for VFR in the UK / nearby europe.
I'm buying it on a "better than not having it" basis, married to an "it's extra information, not to be relied upon, but you never know" attitude.
Ignoring whether the entire concept of TCAS / PCAS, etc is good or bad, can anyone tell me any reason not to buy one, and instead to buy a competing product?
