Bluesounder is a Bluetooth ® BLE linked echo sounder created by Fulcrum Designs specifically for Angling Technics baitboats. Baitboats ordinarily take baits and line to distant locations with the help of remote echo sounders to find optimum locations. Existing echo sounders for baitboats rely on custom designed 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 Apple or Android phone or pad 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, speed 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.
