GPS navigation is not only part of the activities like hiking, sport, geocatching, car and aviation transport on the present but it becomes part of fishing tackle like sonar. GPS navigation equipment for game fishing includes high sensitivity receiver which receives the signals from satellites and calculate your position upon received data. It is usually combo with sonar which enables to place hot spot into the memory during searching of proper fishing area. This you can use for navigation later.

Lowrance and Eagle navigators offer creation of sonar records written on the memory card. The records you can play in sonar or computer at home. You can mark interesting places and hot spots in all records and you can transfer these waypoints back to the navigator for using coordinates for navigation to your points. Your trail is included to the record. All Lowrance HDS models with Structure Scan sonar can record not only water column just under the boat but also underwater space to the sides from you. You can place the waypoint in the space too, not only on your trail, e.g. position 30 metres behind you and 14,3 metres on the right side.

Here you can mark your hot spots without your moving on desired position and scaring fishes. This is one of the reason why are Lowrance and Eagle navigators considered to be the basic fishing equipment. GPS navigation sometimes seems to be unnecessary but it needs only one investment - to buy navigator because GPS service is free of charge.
