Best settings for Insight Genesis

Best Settings COLLAGE FACEBOOKTo make the best possible Insight Genesis custom contour map of your favorite lake, pond, reservoir creek arm or river section, drive your boat pretty slowly, make shore-to-shore up-and-back trips spaced pretty closely together, and record small sonar logs with the correct settings dialed in on your Lowrance, Simrad or B&G GPS/chartplotter.  Mapping is really based on your objectives-better maps at slower speeds and closer boat paths.

Following are all the details in a handy Best Practices Guide you can print, put in a Ziploc bag, and store in your boat.

Logging speed

Recommended Speed –10 mph or less on lakes, reservoirs and rivers for all three layers (contours, veg, hardness)

Maximum Speeds for Desired Outputs:
  • Just Contour Lines – less than 19.5 mph
  • Contours, vegetation, and hardness – Less than 9.5 mph

Recommended boat path

If you’re not logging sonar while you fish, we recommend some map-making methods to create the best map with Insight Genesis. To map an entire lake, reservoir creek arm or section of a river pool, slowly drive your boat in a crisscross pattern, making shore-to-shore, up-and-back tracks across the entire area you seek to map. Some refer to this process as “mowing the lawn.” Complete your survey trip by driving a full circuit of the area as close to the shore as water depth will allow.

For the best results on most bodies of water, space out your up-and-back tracks at maximum 150 feet (a little less than 50 meters) apart. You might, however, want to space your tracks closer together. The tighter your spacing, the more accurate your map’s depiction of fish-holding bottom structure will be.

On ponds or other smaller and/or shallower bodies of water, you’ll get better results by spacing your tracks closer together. Follow these recommendations:

  • 5 acres or smaller – 15 feet (5 meters)
  • 6 to 10 acres – 30 feet (about 10 meters)
  • 11 to 20 acres – 45 feet (about 15 meters)
  • 21 to 30 acres – 60 feet (about 20 meters)
  • 30 acres and larger – 150 feet (about meters)

To assist with track spacing, and to view your progress on the water, use your split screen – with your chart on one side, and your sonar display on the other – and set your chart to show your track/trail

Map-as-you-go option

Reid Miller larger view mapYou don’t have to survey your water body all at once in the manner described above (although that method will give you the best results, the fastest). Another way to use Genesis is to record a sonar log every time you hit the water to fish. That way, you build up a detailed contour map of your best spots visit over time, without additional time or effort. If there’s a particular area you want to ensure you have immediate full coverage of, however, follow the survey tips above.

After making your initial crisscross-and-circuit survey, it’s best to record a sonar log every time you’re on the water and merge all your logs frequently. Merging new sonar logs into your master map increases total coverage, adds greater detail and keeps your map current.

Recommended and required settings

These settings on your Lowrance unit will result in the best custom contour, vegetation, and bottom-hardness maps:

  • Fishing Mode – Shallow Water
  • Ping Rate – 15 pps
  • Range – Auto (Default). This is critical for optimal contours, bottom hardness, and vegetation detection
  • Frequency of Traditional Sonar – 200 KHz or “High CHIRP” (Required)
  • Frequency of StructureScan (if present) – 455 KHz
  • Enable WAAS Differential Correction on GPS — For directions, click this link WAAS Differential Correction for a downloadable PDF.

For step-by-step instructions to follow to dial in these settings, click this link Insight Genesis Recommended Settings — Lowrance for a downloadable PDF.

Recording Sonar
  • We recommend carrying or storing two 8 GB SD cards.
  • We recommend logging no longer than one hour per file. 
  • Do not split both 83 & 200 kHz frequencies, and avoid toggling between screens and adjusting settings while logging data

Transducer placement

We recommend following the Lowrance installation instructions that accompany the unit. Failing to install the transducer correctly could interfere with the sonar signal, preventing collection of accurate data.
