Realistic Sound Level Meter

This analog sound level meter (Model #33-2050 made by Radio Shack) was used by Egon in Ghostbusters II during the battle with Vigo just before Vigo materialized. At different points in the film, both Egon and Ray carried one of these in small pouches on their belts. Its intended purpose remains unclear.
