DS-85 Doppler Speed Log

Highly Accurate Measurements

When a vessel moves through the water, acoustic noise is created and is known as a boundary layer. This noise layer can cause errors with acoustic devices. By measuring speed through water (STW) farther away from the keel, the DS-85 penetrates through this noise and boundary layer resulting in a more stable and accurate speed measurement compared to an electromagnetic speed log.

Better Stability

With the new transducer and newly designed process algorithm, the impact of foam is reduced, enabling highly accurate and stable ship speed information.
