In honor of our old friend Brock Yates, the impresario of the legendary Cannonball Run, we use a system of one to five cannonballs to rank the detectors.

Whistler XTR-520

Pros: Somewhat similar to the Whistler XTR-560 at a slightly lesser cost.

Cons: Even shorter range than the XTR-560, particularly on laser reception. Lacks the Ku band reception of the XTR-560, although that’s not really relevant for most of us.

Bottom Line: A very basic, modestly performing unit.
