Humminbird PC-11 Power Cable for Side-Imaging Units , Black

Great

Product used for portable power supply for sonars!

Bought it for updating the Humminbird inside the house. Just wire it to a 12v 2A source with a fuse and do all your updates and chart plotting from your computer desk.

Does what I purchased it to do.

Fits my helix seven perfectly great price great product

perfect replacement

Helix 10SI gen1 works great.

It works. Does what it is supposed to.

This power cable came exactly as described. It replaced my original one, easily.

Very weak connection. Required the use of the 740129-1 to ensure it stays plugged in. If the unit is jarred the power connection also fails and the echosounder shuts off.
