The Gossen Digisix is a professional, compact exposure meter. This is a hybrid because it features a digital display with measurements in EV but with an analog dial. With an optional accessory, it can be mounted onto a camera shoe. It features a timer for measuring from 0 sec to 30 min, a watch in 12 or 24-hour mode, and a thermometer which can be set to Celsius and Fahrenheit and which ranges from -15°C to +70°C. The Digisix is in excellent condition and works as expected. It comes with a new battery, the original case and lanyard, and the original owner's manual in German and English.
