Features
Stable and highly accurate measurement tool ensures stable speed data, utilizing high frequencies of ultrasonic waves. The JLN-205 has a miniaturized transducer integrated, enabled to install on the bow, a suitable location which has the slightest amount of influence to bubbles.Error Free
An ultrasonic beam is transmitted in fore and aft directions. At the same time, the hull motions such as rolling and pitching are detected and removed by simply measuring the difference of the Doppler shift reception signal, ensuring accurate and stable speed data, even in the roughest conditions.Compact Transducer
The transducer unit is compact and lightweight constructed of molded rubber. It has been designed to minimize the effects of aeration, which allows for stable and accurate operation.
Optimized view
The JLN-205 Doppler log integrates a high visibility 4"LCD display. The main data is displayed in large characters for easy reading. Many display modes, such as normal viewer, instruction comments and graphic viewer are readily available and selectable from the menu.
