So they do work in river canyons? Great!

Any specific models to recommend? Motorola and Cobra brands were

Thanks, T

I bought a set of inexpensive Motorolas. So far they've worked well in
canyon situations, as long as the distance is within a mile or two.
Outside of that range, it's performance falls off to almost nil. I
haven't tried it on a straight line of sight, but I would imagine it
would extend the range quite a bit?
