Now that would explain why the 3cm set picks up a lot of small boat stuff .
...when it's working that is. Both ours are made by Sperry and I wouldn't
give you a nickel for all of them in the whole fleet. Every ship the 3cm
works once in a while and then not well so we normally slave it to the 10cm
for an extra readout station. Ours has been that way for three months. The
other day we were talking about buying a small Furano and wiring it up on
the bridge with a 12 volt battery figuring we couldn't do any worse. So the
10cm picks up the sailboats close in because of that width rule and in the
case below he had three reflectors up? We also get a lot of ghost returns
some do 50 and 60 knots but don't exist! Worse yet we got a bunch of
returns in formation one day in the Red Sea and instead of ghosts turned out
to be the French Navy. Scary!

If you were looking at him with a 10cm set then his mast full of
crumpled tinfoil did nothing to increase his return. The reflecting
surface has to be wider than the wavelength.
