I have a Zaon MRX and would not fly without it now it does not make you look out less in fact it makes you look out more than you already do. It warns you with several beeps through your headset of any transponder signals it considers a threat. It does not mean that there aren’t aircraft in the vicinity that do not have transponders so you still have to look out. I think it is an aid to prudent flying just like GPS, it does not replace a map but can be used in conjunction with one. I say grasp the technology, get one you can never have enough help when your aviating especially with look out!
