MTRMTR ing an extended family of negative discharge sparkers. Fea- turing twin banks of 40 electrode tips, the Dura-Spark L80 can operate in 40 or 80 tip mode, offering energy outputs of either 100 Joules or 200 Joules per shot, which is ideal for very shallow areas. Its small footprint and low power consumption makes it particularly useful on board smaller survey craft with limited deck space and minimal lifting equipment. The Dura-Spark L200 features twin banks of 100 electrode tips that can be ? red at up to 500 Joules per shot concurrently, independently, in ? ip-? op mode, or with a combination of ? re delay or split ? re delay. Making its ? rst appearance during the second half of 2019, the Dura-
