Have you ever wanted to view your BioBase EcoSound trip in even more detail? The trip simulator feature available on Lowrance sonar units is a great way to take a closer look at your trip for troubleshooting, or just to identify areas of interest for your next field day. First thing we recommend you do is to purchase an AC to DC power converter so you can run your Lowrance on a work bench or desk. That’s a lot easier than running off of a 12 volt battery that you’ll have to continually recharge. Once you get your unit’s power supply, we’ll walk you through how to view and replay your previously recorded sonar log in simulator on your Lowrance (it works on Simrad too).
Select the Sonar Log for Simulation
Figure 1. Begin on the home screen and select settings
Figure 2. scroll down to simulator
Figure 3. Turn on simulate, but make sure demo remains off.
Figure 4. Select the file that you would like to simulate. It is always a good idea to give your sonar logs descriptive names so they are easy to identify! Re-record Logs to Recover Areas Lost to Corruption
Figure 5. Select “Advanced”
Figure 8. Tap power button and select “Log sonar”
Figure 9. Name the sonar file, then select “Record”
Figure 10. After starting recording, select “Log sonar…” again to see time remaining. Select “Stop” about 30 seconds before the time remaining ends. Get a Deeper Look at Your Sonar Log
Figure 11. Sonar simulation with standard settings.
Figure 12. Adjust sensitivity setting to improve the appearance of the log. Turn sensitivity down to reduce excess noise in the sonar image. Turn the sensitivity up to brighten washed out logs. 
Figure 14. Adjusting the colorline can also affect the appearance of the sonar log. Turn the colorline down to reduce excess noise in the sonar image. Turn the color line up to brighten washed out logs. 
Figure 15. Turn on the depth line to see where the depth was measured. This can be a great tool when working in areas with soft, mucky bottoms. Consult this blog about how the depth line can help you correlate depth in BioBase with depth on your display.
Mark Waypoints for Use in BioBase or in the Field
Another useful feature that many BioBase customers love is waypoints. While you may know that you can collect waypoints on your Lowrance unit while on the water, did you know that you can also collect waypoints using simulator after you have returned from the field? This feature is great to mark areas you may have missed the first time around or to help mark areas for editing in BioBase or Arc GIS. To mark a waypoint using simulator, just follow these steps:
Figure 19. The waypoint that was set within the sonar log is now displayed on the chart.
