The design and construction of the SAL R100 Speed Log is the result of decades of research and development, iterations and innovation. The latest addition to our Speed Log is a tank installation option that we call Easy TankTM – a cost-efficient alternative to the Sea Valve and traditional tanks, creating possibilities for installations in very tight spaces. Easy TankTM is approved by DNV GL and is considered a closed-ended installation. It requires no watertight compartment and is available for both Steel and Aluminium hulls.

Regardless of which installation option you prefer, SAL R100 provides robust and accurate speed-through-water (STW) measurements thanks to the unique acoustic correlation technology. Read more about our products here or contact one of our resellers!
