Bridge Equipment and Systems Volume 3: Speed Log and Echo Sounder (Elstan’s® Pocket Book Series)  (Paperback, Elstan A. Fernandez, Prosanjeet J. Sarkar)

This pocketbook is based on an extract from the book titled Bridge Equipment for Navigation and Control of Commercial Ships. It deals with understanding the Ship’s Speed Log and Echo Sounder. The Pocket Book Series was introduced based on the fact that there is a changing trend in the way books are read today. The new normal is that readers and students prefer to read specific, and not so voluminous content, in the least time, as time comes at a premium these days.
