Narrative:

We were just starting our descent to bullhead city/laughlin when we noticed an small aircraft pass from south to north at our last altitude. We had been using ZLA for VFR advisories. When I contacted the controller to inform them of the near miss, they stated that they showed no primary or secondary target on radar. The lesson I learned is that even though using VFR advisories, I must maintain a high level of vigilance for traffic (yes, I know, I have heard this before from many pubs). We do not believe the other pilot ever saw us.

Title: SMA ON DSCNT HAS NMAC.

Narrative: WE WERE JUST STARTING OUR DSCNT TO BULLHEAD CITY/LAUGHLIN WHEN WE NOTICED AN SMA PASS FROM S TO N AT OUR LAST ALT. WE HAD BEEN USING ZLA FOR VFR ADVISORIES. WHEN I CONTACTED THE CTLR TO INFORM THEM OF THE NEAR MISS, THEY STATED THAT THEY SHOWED NO PRIMARY OR SECONDARY TARGET ON RADAR. THE LESSON I LEARNED IS THAT EVEN THOUGH USING VFR ADVISORIES, I MUST MAINTAIN A HIGH LEVEL OF VIGILANCE FOR TFC (YES, I KNOW, I HAVE HEARD THIS BEFORE FROM MANY PUBS). WE DO NOT BELIEVE THE OTHER PLT EVER SAW US.
