The 1988 Gossen Spot-Master (in US Ultra-Spot) is a hand held spot exposure meter. It has a reflex viewing system with 15° angle of view, within this is marked a 1° circle where light readings are measured by a fast-acting Silicon blue photocell. The display is an LCD readout surrounding the viewing area. Both ambient and flash light can be measured.

Measurement modes are: ambient, flash, EV, zone, and cine. When measuring flash the corresponding ambient light setting is also displayed.

The meter will average up to 10 ambient readings. It will also store readings according to the zone system, averaging the highest and lowest.

The 1994 Spot-Master 2 has minor revisions, operation and specifications are identical.
