Underwater Detectors

All SED and SEL series detectors are available in underwater SUD, SUL, and SHUD versions, respectively. Every underwater detector is pressure tested to 40 meters depth (60 psi). The 'W' quartz diffuser is required to withstand the pressures of underwateruse. Filters are optional, with O-ring seals between all filter rings. Standard SUD detectors come on a 100 foot long, water-blocked cable (Polypropylene reinforced cables up to 600 feet available). The anodized aluminum components provide excellent corrosion resistance to salt water, for all-weather durability.
