Bluesounder is a Bluetooth ® BLE linked echo sounder designed specifically for baitboats used in the sport of coarse fishing. Baitboats ordinarily take baits and line to distant locations with the help of remote echo sounders to locate optimum locations. Existing echo sounders for baitboats rely on conventional monochrome LCD displays to provide visual depiction of the bed of fishing waters. Bluesounder interprets the existing radio transmissions from these baitboats and passes them to an iPhone or iPad to display a much more detailed image with choice of colour schemes. The display can be frozen, swiped back in time so that the last few minutes of depth profile can be reviewed and the units and zoom levels can all be changed to suit the user and conditions. A radio transmission strength (from the baitboat) indicator and Bluesounder battery condition meter are present to provide all the information you need to survey your venue and find that perfect spot.
