Narrative:

The bizjet suddenly appeared at about 3 O'clock position (to my right) at probably less than 2000 ft away. I don't think I saw it until the aircraft turned away from me. We were below the andrews AFB class B airspace floor right at the shore of the chesapeake bay. A contributing factor is using a new handheld GPS for the first time. This may have distraction me from my normal traffic scan. After the near miss, I confirmed my altitude of 2000 ft. Upon approaching sby, I verified my altimeter setting was within 100 ft.
