Since walleye are typically suspended over deeper waters among open water schools of forage fish, summertime walleye anglers use depth sounders
to locate concentrations of suspended forage fish.
Using GPS, depth sounders
, masks and snorkels, video cameras and notebooks, we `anchored' the image in three-dimensional reality, as well as mapping the reef's ecological zones and their health.
A spokesman for North Wales Police said items stolen included Global Positioning System navigation units, depth sounders
and outboard motors.
In the relatively shallow waters of Northern Europe, navigators could also use sounding lines or depth sounders
to determine the depth and type of sea bed (sand, silt, or rock) giving expert navigators information about their position, and this all figured in the corresponding rudder charts.
While Marine Tech's speciality is the servicing and maintenance of outboards, Adam will do all manner of installations from depth sounders
, bass motors, wiring and the actual motors themselves, on site.
