Its rugged gray finish withstands harsh conditions, ensuring reliable, high-speed connectivity between Lowrance devices and beyond.

## Description

The Lowrance Ethext-15Yl Ethernet Cable is made to withstand the toughest onboard marine environments. The cable networks any NMEA-certified sensor on the boat such as sonar, GPS and multifunction gauge, regardless of brand, to share or display user-selectable data with other instruments installed on the network. For example, the use of a fuel-flow sensor in conjunction with a GPS or speed sensor can provide detailed information to help you manage fuel consumption and calculate range.

Review: Connects like a dream… - I installed this cable on my 17' fishing boat so that I could have one Lowrance HDS unit on the steering console, and another on the bow of the boat. After fighting the boat for a few hours (it did not want another cable installed, or was it that I didn’t want to cram my arms and hands into the tightest areas of the boat?) I connected the two units and they work seamlessly. One note about my installation: the cable hole in my dash was not big enough to fit another connector through it. I didn't want to drill another hole in my dash just for one additional cable, so I cut the cable and fed the cut end through the existing hole in my dash. Then I spliced it together with conventional connectors. I was concerned about how well it would work after doing that, but it turned out to work perfectly. I am not saying this is something you should do, I'm just pointing out that it is possible in tight situations. Your results may vary.
Review: rear transducers working on the front deck. - Nmea 2000 cable does not share transducer info. this cable is required to use any transducer that works on both Gen 3 units.

### ⭐⭐⭐⭐⭐ rear transducers working on the front deck.
*by A***Y on 20 November 2018*

Nmea 2000 cable does not share transducer info. this cable is required to use any transducer that works on both Gen 3 units.

### ⭐⭐⭐⭐⭐ Solid product
*by E***. on 22 November 2013*

Great product...the answer to my data sharing between Lowrance chartplotter HDS Gen 2 Touch units. I find all Lowrance products above standard. VERY IMPORTANT: measure the exact route this cable will take from one area to the next before you order. You may find that you will need the longer length size.
