16: How do I use the Garmin Echomap UHD2 to find fish?

 

Here are some examples of how to use the Garmin Echomap UHD2 to find fish:

 

  • Use the sonar image to look for structure. Fish are attracted to structure because it provides them with food and shelter. Look for areas with reefs, weed beds, drop-offs, and other types of structures.
  • Look for baitfish. Baitfish are a major food source for most fish species. If you see baitfish on the fishfinder, it is a good indication that there could be larger fish nearby.
  • Look for fish arches. Fish arches are marks on the fishfinder image that indicate the presence of fish. The size and shape of the arch can give you an idea of the size and type of fish.
  • Use the Chartplotter to mark waypoints and tracks. Once you have found an area where there are fish, you can mark a waypoint on the fishfinder or track so that you can easily return to that spot in the future.

Here is an example of how you might use the UHD2 to find fish on a typical fishing trip:

 

  • Start by turning on the UHD2 and selecting the fishfinder mode.
  • Use the chart plotter to navigate to a known fishing spot or an area where you have seen or marked fish in the past.
  • Start watching the Fishfinder and look for structures, baitfish, and fish arches.
  • Once you have found an area that looks fishy, mark a waypoint or track so that you can easily return to that spot in the future.
  • Throw out a few test casts to get a feel for what’s there. Then, it just takes some practice.

Here are a few additional tips on getting the most out of your UHD2 to find fish:

 

  • Use the zoom feature to get a closer look at the sonar image. This can help identify fish arches and other small targets.
  • Try using the split screen feature to view two different sonar images at the same time. This can help compare different areas or for viewing different sonar modes at the same time.
  • Experiment with different sonar settings to find what works best for the conditions you are fishing in.
  • With some practice, you’ll start getting a good feel for what areas hold fish and which ones don’t, and also what different types of fish look like on the screen.

17: How do I use the Garmin Echomap UHD2 to navigate?

 

To navigate, you must choose a destination, set a course, or create a route, and follow the course or route. You can follow the course or the route on the Navigation chart, Fishing chart, Perspective 3D chart view, or Mariner’sEye 3D chart view. 

 

The image above shows the different look between a Navigation Chart and a Fishing Chart.

 

You can set and follow a course to a destination using one of three methods: Go To, Route To, or Auto Guidance.

 

  • Go To: Takes you directly to the destination. This is the standard option for navigating to a destination. The chartplotter creates a straight-line course or navigation line to the destination. You need to be careful here, as the direct path option may run over land and other obstacles.
  • Route To: Creates a route from your location to a destination, allowing you to add turns along the way. This option provides a straight-line course to the destination but allows you to add turns into the route to avoid land and other obstacles.
  • Auto Guidance: Uses the specified information about your vessel and chart data to determine the best path to your destination. This option is available only when using a compatible premium chart like Garmin Navionics+. It provides a turn-by-turn navigation path to your destination, avoiding land and other obstacles.

 

The image below shows how a route might look on your navigation chart.

 

 

Building a Route

 

 

Here are a few common UHD2 Navigation Questions:

 

How do I make the Chartplotter point me in the direction in which I want to go?

  • Tap a location on the Chart and Navigate to the waypoint using the “GoTo Button”.

 

How do I make the device guide me along a straight line to a location using the shortest distance from the present location?

  • Build a single-leg route and navigate it using the “RouteTo Button”.

 

How do I make the device guide me to a location while avoiding charted obstacles?

  • Build a multi-leg route and navigate it using the RouteTo Option.

 

Can the UHD2 create a path for me?

  • If you have premium maps that support Auto Guidance and are in an area covered by Auto Guidance, then yes Auto Guidance can build a multi-leg route for you between two points.
