To expand: My experience with these simpler devices is that if you have
more than, say, two close-by targets (a typical situation in a busy
pattern), they become useless since you'll be busy looking outside. I
turn our voice alerting off on the Monroy in these cases, since it will
just say "traffic nearby" all the time and show a distance of a mile. I
know that already, so I look outside.

I'm not familiar with the Monroy, but it's threat determination doesn't
sound as good as the MRX. To quote from a post I made:

"I'm also using an MRX. I believe it's warnings are also based distance
and altitude trends, not just distance and altitude. For example,
consider two aircraft the same distance from you and the same altitude
above, one descending and one ascending. Only the descending one will
trigger the alert signal."

In other words, the MRX "advisory" and "alert" warnings are not based
just on traffic being nearby, but actually approaching your position. In
addition, it displays distance down to 0.4 mile.
