Recently decided to replace the Garmin
Echo 100 I had on our dinghy
with a Raymarine
Dragonfly 4 Pro.
was just a depth sounder
. It has two plugs at the back, one for power, the other for the transducer. I had issues with corrosion
in the plugs, if the power cable wasn't just right, it wouldn't power up. Lately the temp gauge became 20-30 degrees F off, which I'm guessing may have been a corrosion
issue as well. It was installed for about 1.5 years, and kept on the dinghy
in the elements after the cables
I figured it would die completely as soon as we left for Mexico
, so I decided to replace it with the Raymarine
unit. The raymarine unit has GPS
as well as the fancy new see underwater sonar. I figured if I was somewhere sketchy I could launch the dinghy and check out the anchorage before bringing the mother ship in.
Enough background, here's the real meat of the post. During the install I was surprised to discover that the Garmin unit came with tinned wires and a fuse, where as the raymarine wires are copper and the fuse you must supply yourself. The fuse isn't that big of a deal, but not using tinned wire? I was happy to see that the Raymarine only had one connector, and it was big and beefy, so hopefully it will hold up in the elements better than the Garmin.
