While many users are skeptical about spending hundreds of dollars on a depth finder, no one can deny their utility in refining the fishing trip’s effectiveness. So, investing in a depth finder is a good idea if you’re struggling to find a better fishing spot.
Recently many users have been talking about the Simrad Cruise 7 Depth finder. It is a phenomenal unit that brings many features to the anglers.
However, there has also been a slight increase in the number of complaints regarding the functionality of your unit.
So, let’s cover a few of these common issues and how you can get around them if your Simrad Cruise 7 Depth finder is not working.
Simrad Cruise 7 Depth Finder Not Working?
- Check Transducer Connection
The transducer connection is the first thing to check when your Simrad Cruise 7 depth finder is not working. The transducer sends the sound waves into the water to measure the depth.
If the transducer is not connected correctly, then the depth finder will not be able to function.
To connect it, first ensure the power is off to the depth finder. Next, locate the transducer port on the back of the unit. It will have a rubber grommet around it.
Take the transducer cable and insert it into the port. Push it in until it is snug. Once it is in, screws on the retaining nut to hold it in place. Finally, turn on the power to the depth finder and test it out.
- Check Settings
If your transducer is connected correctly and you are still having issues, then the next thing to check is the settings. There are a few different settings that can affect the performance of the depth finder.
To access the settings, press the menu button for three seconds. This will bring up the main menu. Click the arrow keys to the “Settings” option and enter.
The first setting to check is the “Depth Range.” This is how deep the depth finder will measure. If it is set too shallow, it will not pick up the deeper depths.
The following setting to check is the “Frequency.” This is how often the sound waves are sent out. A higher frequency will give you a more accurate reading but will also use more battery power.
The last setting to check is the “Transducer Type.” Make sure this is set to the correct type of transducer you use.
- Adjust Sensitivity
If you are still having issues, the next thing to try is adjusting the sensitivity. The sensitivity controls how sensitive the depth finder is to sound waves.
To change it, press and hold the menu button for three seconds. This will bring up the main menu.
Click the arrow keys to the “Settings” option and enter. Then use the arrow keys to scroll to the “Sensitivity” option and press enter. You can then use the arrow keys to adjust the sensitivity up or down.
- Restart Depth Finder
If you have tried all of the above steps and your depth finder is still not working, then the last thing to try is restarting it. To do this, press and hold the power button for three seconds.
This will turn off the depth finder. Please wait a few seconds and then press the power button again to turn it back on.
- Look for Corrosions
If you still have issues with your depth finder, there may be corrosion on the cable or the transducer itself. If this is the case, you will need to replace the cable or the transducer.
First, disconnect the transducer from the depth finder to identify corroded areas. Next, inspect the cable and transducer for any green or white buildup. If you see any, then that is corrosion.
To clean it off, you can use a wire brush or sandpaper. Once you have removed all the corrosion, reattach the transducer and try the depth finder again.
- Perform a Cavitation Check
If you are still having issues with your depth finder, there is possible cavitation. Cavitation is when air bubbles form on the transducer. This can cause the depth finder to give inaccurate readings.
First, disconnect the transducer from the depth finder to check for cavitation.
Next, place the transducer in a bucket of water. Turn on the depth finder and see if it gives accurate readings. If not, then there is cavitation present.
To fix this, you will need to clean the transducer. To do this, first, remove any dirt or debris from the transducer. Next, place the transducer in a bucket of clean water.
Add a few drops of dish soap to the water and stir it around. Let the transducer soak for a few minutes, and then remove it. Rinse it off with clean water and dry it with a soft cloth. Once it is dry, reattach it to the depth finder and try the depth finder again.
- Speed Problems
One of the most common issues with this depth finder is that the unit will stop working once you increase the speed of your boat.
This situation can be tricky to deal with when you don’t know how to better manage the transducer’s location.
The best thing you can do to overcome this issue is to relocate the transducer to another position deeper in the water.
Relocating the transducer will simplify the unit’s work, as the water bubbles won’t interfere with its essential functions.
On the other hand, if you can’t relocate the transducer, then the only thing left to do is manage your boat’s speed to limit the water’s disruption.
That way, you will get an accurate reading, and the unit will keep working flawlessly.
With that said, you can always call an expert to manage the depth finder installation better. It will eliminate the problems with depth reading while driving the boat.
- No Reading
Aside from the speed problems, users often complain about no depth reading even when the boat is not moving.
Most of the time, this issue can be traced back to a defective transducer, and you’ll have to either clean or replace the transducer to get everything working again.
If you bought the transducer a few months ago, you wouldn’t have to bother with extensive troubleshooting steps.
All you need to do to get around this problem is to remove the transducer from the housing and clean it with a dry cloth. Your primary focus should be removing all the marine growth and weeds from the bottom of your transducer.
That way, your transducer will be able to get accurate readings without running into interferences with the depth finder.Ideally, the issue should be fixed at this point, and your depth finder will start working perfectly.
However, if you’re still running into the same problem and there is no reading on the unit, then there is a good chance that you’re dealing with broken connection points.
To fix this issue, you just need to fix the wiring and clean the corrosion from the connection points, and everything will be in order.
- Issues with Shallow Water
Lastly, users have complained about struggling to manage the depth finder in shallow water.
If you’re in a similar situation and the unit just won’t show accurate readings on shallow water, then there is a good chance that you’ve not managed the sensitivity settings.
To avoid this issue, you must turn off the automatic settings and manually reduce these settings.
After reducing the sensitivity, you can cover the same area again; hopefully, you won’t have to bother with the same problems. You will be able to fix the issue in no time as long as your transducer is in perfect condition.
Otherwise, you will have to clean the transducer and remove all weeds from the bottom section of your boat.
These were a few issues that users were struggling to manage while using the Simrad Cruise 7 Depth finder. Luckily, most of these issues can be easily fixed, but if you’re still unable to fix your unit, then your only option is to reach out to customer support.
Just call the company number and explain the issue to them. That way, you will be able to isolate the problem quickly, and the unit will keep working flawlessly.
