small fish finder gps combo
GPS fishfinders that integrate sonar are also very useful for fishing. With an in-built GPS, these devices can pinpoint your fishing spot in seconds. CHIRP (continuous inertial reference pulse) sonar technology allows you to see fish's habits and feeding patterns in a much more detailed way than traditional GPS. Any fisherman will appreciate a GPS fish finder that can display a greater than 7 inch screen.
Fish ID displays a fish icon whenever sonar returns find fish. The Flasher function gives a more abstract view and is suitable for ice-fishing enthusiasts. Split Zoom lets you magnify a portion of your sonar view. The function can be used in tandem with a regular display using split-screen capabilities. The Bottom Lock function focuses sonar pings towards the bottom of a water mass.
Display screen is the most important aspect of a chartplotter and fishfinder combo. The largest, highest resolution screen is what we choose. A couple of 5-inch screens that we have tested have resolutions exceeding 150 pixels per inch. This screen will display incredible detail but must be seen from close proximity.
The supplied transducer features a transom-mounted mount, a built-in probe for water temperature and a 20-foot length cable. A temperature graph function displays the difference between surface temperatures and the water currents underneath the surface.
GPS fishfinder combos also have the added benefit of being waterproof. While some units are IPX7-rated for water resistance, they lack Ethernet connectivity. Make sure you choose a unit that's water resistant if it is going to be in heavy rain or deep waters. Water-resistant units make up the majority of good quality. However, rain resistance ratings and depth will influence the quality of your unit.
