I really love my BF Goodrich TCAS.
I used it this morning, I like it very much.
Does it give me a false sense of security - absolutely not, it does enable me to locate traffic that my eyeball struggles to and makes me feel safer when in the soup.
It overlays on my G1000 MFD so there is no loss of situational awareness.
I still look outside, in fact it speeds up acquisition of traffic so much I have more time to scan the rest of the sky when VFR.
A safety plea - if you have a mode C transponder then please switch it to ALT, it lets those of us who have this great technology see eachother and also see those who don't have it.
