PCAS Monroy ATD-300

[kmach]

Hi everyone,

I had a close call last week and am considering a passive collision
avoidance system.

I think my wig wag landing lights and strobes from Aeroleds saved my bacon. the 172 passed level from 1 oclock to my 9 from out of the late evening sun while I was in the downwind of a private unregistered strip. I had completed a position report on the enroute freq a minute or two earlier and changed to the airfield freq and called the downwind, I was completing the landing check, when my passenger called "plane", I looked up to see it go by at the 11 pos 100yds away. I think if I didn't have a passenger , I don't think I would of ever known of it's presence!

I have tried the Zaon XRX last year , but was unable to calibrate its internal compass , it did not like the electonics in my dash, so I sent it back.

I am now considering the Monroy ATD-300 with the externally mounted antenna .



I know of the pcas limitations , but, just maybe one might save an incident, alerting of an aircraft that your mark II eyeballs can't see while your head is swiveling, also a person has to look at the panel once in a while !

Anyone use one of these, are they another useful tool ? Experiences ?
