Sonar Reflections


A good sonar unit may not be essential when fishing offshore, but it sure helps! This article covers some of the more subtle points on sonar selection and use that we encountered while setting up Toy Boat 2...

When we put Toy Boat 2 together, one of the requirements we had was to make use of as much existing equipment as possible. This included moving our old, reliable Lowrance X-85 sonar over from Toy Boat 1 .

We had some concerns about the move. The X-85 was a 375 watt (RMS) monochrome LCD fishfinder, with a 192 kHz, 20 degree transducer. At the time it was purchased, it was the "gold standard" in freshwater sonars, but we had read a lot of negative things about Lowrance units in saltwater on the Internet. Still, having owned a total of 6 Lowrance/Eagle units over the years, we had developed a certain amount of brand loyalty, and wanted to find out for ourselves what the issues really were.

So we started by moving the X-85 to Toy Boat 2, and doing our honest best to squeeze as much out of the unit in offshore use as possible.

When we finally encountered some issues with the unit which forced a replacement, we decided to switch over to a comparable Furuno unit (the LS-6100), and repeat the process.

We weren't expecting a lot of material differences between the two, but in fact, we were startled at how different the two sonar units were in terms of usability and performance. But the Furuno unit was not always better.

Admittedly, the specifics of this comparsion are somewhat dated - the X-85 is long gone (the closest thing they offer now is the X-125), but in the course of going through this process, we wound up learning a lot of general things about sonar installation, use and performance that we had never thought about before. Most of these things are still valid, so we thought we'd pass them along, as they may help you make a better decision when selecting a sonar unit for your skiff.
