Bottom layer auto shift
The bottom layer (E) has the ability to automatically shift and display the measuring depth according to the ups and downs of the sea bottom. This is a great source of information for efficient fishing and for the safety of your nets.
Automatic bottom current tracking
Normally run automatically, the new JLN-650 allows bottom tracking with depths up to approximately 400 meters1, measuring direction and speed relative to the sea bottom. If sea bottom becomes too deep, it automatically switches to water tracking mode or through GPS mode, depending on user selection.
Five depth layers
The JLN-650 Doppler current meter allows continuous display of tidal currents at five depths layers (A, B, C, D, E) simultaneously, of which each layer is measured in four directions: port ahead, starboard ahead, port astern and starboard astern. The user can select the depth of each layer, showing different information. You can also select bearing2 displayed as North-up (with true north at the top of the display) and Head-up (with bow at the top of the display)
Fish finding
You can view fish echoes in four-directions, two-directions ahead, or in any one direction, allowing for easy fish tracking. Just as any typical fish finder, you can set the display to the type of fish or sea conditions simply by adjusting the sensitivity.
