Are these units reliable and worth having in your glider?

Are they consistent enough to trust in a real threat situation?

Yep, too bad they went out of business. Have to say that despite it's shortcomings that it was a decent inexpensive bit of kit for traffic SA. Having said that, I had contacted their support just before they went out of business due to a filtering problem with my MRX. It was sporadically picking up targets and sporadically picking up my squawk code. They replied to my email support request with advise on how to fine-tune the sensitivity inside the "Admin" menu. Their response ...

" ... You can adjust the suppression level to adjust to your transponder by
entering the admin menu. (Mute + Down buttons) Once in Admin, press
ENTER/MENU to skip through the altimeter adjustment, and you should see a
screen which shows "P000 009" You can change the right side values between 5
to 20 to capture your transponder. Every transponder and aircraft vary so we
have this adjustment to allow for variations. You must hit ENTER/MENU after
adjusting the level to save it. (The screen will then return to normal view) ... "

If you try this, just be careful. Write stuff down before you make changes. I did not do that and now I am not sure what the factory default setting was on my MRX. It may have been "P000 009" as indicated above but I am not certain of that. If anyone knows what the factory default sensitivity setting should be, please post it here.
