V1 is very noisy. But the arrows do help a lot with deciphering what threats are real and what aren't. Quite often I pick up cheaper radar detectors from people driving past me. At first the V1 picks up a strong signal in front, but as the car passes me it quickly shows to the side then behind and I know it wasn't a cop. Also helps you figure out if it's from a store because it usually just shows the side arrow as you're passing, which is good where I am because both stores and cops are on K band here.
