The bigger screen on Helix 7 along with the great pricing attracts servers and countless anglers with the ideal fishing system. You won’t have to worry about spending thousands of dollars on the equipment and installation fees to make use of this device. It is at the top of the list for many experts and beginners, so make sure to test it out if you’re in the market for a mid-tier fish finder. However, it is not all sunshine and rainbows with the Humminbird Helix 7. You will occasionally come across minor issues with this fish finder that can be pretty annoying when you’re out on a fishing trip. So, it is better to be prepared, and the following list of common problems with Humminbird Helix 7 will give you more perspective on the situation.
Common Humminbird Helix 7 Problems
1. Helix 7 Won’t Start
Power-related issues with the Helix 7 are pretty common and can often be traced back to missed installation instructions. If the power connectors are not managed properly, or the voltage output from the battery doesn’t match the demands of the Helix 7 unit, then you will also be running into the same problem.
To fix this problem, you will have to isolate the issue by using a multimeter. If the battery is drained, then you’ll have to get a replacement immediately. Similarly, damaged wiring should also be replaced quickly to avoid further complications.
2. Transducer Problems
Anglers often struggle with securing output from the transducer. This problem is pretty serious, and you won’t get any information on the screen when the transducer is not sending any information. Luckily, the cable is the main culprit behind this problem, and you can inspect the connector pins along with the cable to isolate the problem. In case the cable is damaged or frayed, securing a replacement is the only real option.
3. Fish Not Showing Up
When fish is not showing up on the Humminbird Helix 7 system, you will have to go over the sonar configurations. Most of the time, you’re running into sensitivity and filter issues. Moreover, Fish ID features can also block the fish from showing up on the screen. So, you need to turn off the extra features altogether and then turn them on one by one to narrow down the malfunctioning configurations.
4. Missing Depth Readings
When the frequency is set too low, you won’t get any depth reading from the system. It is true that the lower frequency helps you get a broader perspective of the activity below your boat, but you need to switch to the higher frequency to get to the bottom. So, try accessing the sonar setting and turning to a higher Chirp frequency. This will be enough to get the depth reading back, and you should double-check the transducer connection to further improve this situation.
5. Excessive Clutter on Display
The presence of too much information on the display is also an issue as you won’t be able to find any useful information. Many anglers complain about this issue, and you will likely run into this situation when the clutter configurations are not appropriately managed.
All you have to do is to turn up the clutter management features on the unit and find a spot where you’re only getting the desired information on the screen. Keep in mind that turning up these features too much will remove all the information from the screen. So, try to make small increments and then test out the performance from the Sonar System.
6. Display Losing Power at High Speed
Lastly, you will often come across situations where the system will lose power at high speed, and you won’t get any response from the display. This issue with the display points toward power interruptions from the battery. Ideally, you need around 20 volts of consistent output from the battery when using this unit. So, if the battery is in poor condition, just get a replacement.
Overall, these were some of the common issues that you will experience with the Humminbird Helix 7 unit. For the majority of these issues, you will be able to fix the situation within a few minutes. However, if you’re running into hardware issues, then calling the Humminbird dealer is your best move.
