Not much of a problem this side of the Pond.
I'm on the same side of the pond as you...just a little farther downrange.
In my view anyone who believes in see and avoid should go fly with someone who has TAS
I have no idea what TAS is..traffic alert systems, perhaps...but I generally use TCAS II...and I'm the missionary of see and avoid. Moreover, it's not just a good idea. It's the law.
Provided you are using the unit in VFR,...
It's very VFR presently, operating under VFR...but night, dark, few references, and a LOT of traffic, much of which isn't reporting, much of which can't. Simply being VFR means very little...because a VFR night here is still hard instrument conditions.
You were probably using one of the earlier units.
I was not.
I have run mine alongside TAS and over around 10 hours I did have a single false warning.
I have run them for several hundred hours in a variety of different aircraft and different units...not earlier ones...and have had hundreds of false warnings.
