Explorer DVL - Piston

Product Name:Explorer DVL - Piston
Product Description:
Year of introduction:
System components:Introducing the EXPLORER Doppler Velocity Logs (DVLs) offering precision navigation solutions designed for your littoral to mid-depth endeavors and ideally suited for your small lightweight vehicles and/or low power/long endurance applications. Explorer’s innovative design consistently delivers high accuracy, precision Doppler navigation and current profiling capability, in a compact package designed to meet the stringent weight and power constraints of today’s next generation vehicles. Remote or self-contained, shallow water or deep, the Explorer family of DVLs has a navigation solution ideally suited for your unique system requirements. Explore the possibilities with the multiple external sensor drivers included as well as an optional ntegrated PNi TRAX AHRS IMU.
