As soon as I purchased my new skiff some three years ago, I had to have the latest and greatest fish-finder/GPS machine. I got it installed, but once I turned it on, problems followed. The software on my machine had some initial problems that were later corrected. Still, I needed to load a new version of the operating software.
That simple operation involved downloading the updated system from the manufacturer’s Internet site onto a computer, transfering it to a storage device and plugging that into my finder/GPS unit for automatic update. I somehow botched the operation and had to send the unit back. The manufacturer reloaded everything and promptly returned it.
Doing some Internet research on my new unit, I quickly set a few basic parameters and barely touched the settings again. It worked well, much better than the 15-year-old unit I’d had before, but I couldn’t help thinking I wasn’t using the machine’s full potential. This winter I decided to fix that.
Beneath the Iceberg
The electronic fish-finder is the most revolutionary tool available to anglers. It’s a tool with a story that dates back to the sinking of the Titanic.
The part of the iceberg hit by the cruise ship was underwater and unobservable to the navigating crew. After that disaster, work immediately began on how to detect below-surface objects. First developed was an echo-ranging apparatus based on the navigational methods of dolphins.
Reginald Fessenden, a Canadian working for a U.S. company in Boston, patented the first workable sonar —Sound Navigation and Ranging — device in 1912. Submarine warfare in the Battle of the Atlantic during World War II greatly accelerated its development, first by Britain, then the U.S.
The fish-finders we use today are spinoffs of that defense technology. Over the years, they have become so accurate and complex that they are prohibited from export by U.S. law. They’re so sophisticated that many anglers — I being a poster boy — fail to get the most from their units. There are just too many options for a simple fisherman like me to comprehend, let alone remember how they interact.
Learning the Machine
There is, however, a solution for us technologically inept. Almost all retailers of such units have at least one employee expert in their setup and use. In talking to a number of them over the last week, I have found them all eager to help, especially during the slow times of winter. Just disconnect your unit from the boat and take it to the store.
The expert there can hook it up in-house and go over the settings, explain the options and suggest changes for your type of fishing.
There also may be software upgrades available from the manufacturer. These are generally free and can be downloaded pretty easily.
It is wise to call ahead to make sure that the right technician will be on hand and that they service your brand.
If you have a GPS (the satellite-based Global Positioning System) unit combined with your fish-finder, you can review it as well. You can also discuss aftermarket products, such as navigational map overlays.
Wintertime is slow for both marine stores and anglers. Availing yourself now of the expertise that the stores offer will pay off in fish in the box and fun on the water in 2014.
