Forward Looking Sonar -Just brilliant !!! Two parts to it, the through hull sensor and the display connected by a cable. The sensor looks forward 7.5 degrees either side of centre and is best mounted along side the keel so that is protected by the keel from nets and lines. The display has 3 settings and in this case is showing an average water depth of 14 metres out 50 metres ahead. You can see sections of the anchor chain descending from the bow.
