Humminbird PC 11 - Filtered Power Cable (6ft)
720057-1Compatibility:
Clean Power for Big Screens
If you are getting interference on your fish finder or need to wire a new unit, the Humminbird PC 11 (720057-1) is the heavy-duty filtered power cable you need. This 6-foot waterproof cord is designed specifically for larger HELIX and legacy Core series units that draw more current.
Built-In Noise Filter:
Unlike standard power cords, the PC 11 features an integrated choke block. This built-in filter helps eliminate electrical interference (RFI) from your outboard motor, trolling motor, or other electronics, ensuring you get the clearest possible sonar and Side Imaging picture.
- Inline Fuse Required: This cable does NOT include an inline fuse. You must install the proper size fuse (typically 3A to 5A, check your unit's manual) to protect your expensive electronics from power surges.
- Model Specific: This cable is too large for smaller HELIX units. Do not attempt to force it into a HELIX 5 or HELIX 7.

Frequently Asked Questions
Does this cable come with a fuse?
No. The PC 11 power cable has bare wire leads at the end. You will need to purchase and install an inline fuse holder separately before connecting it to your battery or fuse block. Check your specific unit's manual for the correct fuse rating.
What is the heavy block on the cable?
That is the built-in noise filter (choke). It is designed to isolate your fish finder from electrical interference generated by your outboard alternator, trolling motor, or bilge pumps, which keeps your sonar screen clean and clear of vertical lines.
Will this fit my HELIX 7?
No. The HELIX 5 and HELIX 7 use a slightly smaller power connection and require the standard PC 10 power cable. The PC 11 is specifically molded for the larger HELIX 9, 10, and 12 units.
