Just about everyone who has used a high definition sonar/GPS unit or the newer underwater video machines has come to the conclusion these fishing tools are invaluable for finding fish, structure and fish holding cover. The problem with these units is they pull a lot of amp power and if you’re not prepared dead batteries are going to be the norm of the day!
In my boats I rig two cranking batteries wired in parallel (positive to positive and negative to negative) to double the amp hours and keep the voltage at 12 volts. Typically I use two 27 group batteries with the one being connected to the outboard a cranking battery and the one powering accessories a deep cycle model.
Not only do large screen sonar units require a lot of power to operate, even when switched off they have a static amp draw that can ruin a battery if not managed properly.
If there isn’t room in your boat for two batteri...
It’s true that no fishing boat is perfect and/or capable of doing all the things an avid angler might have interest in. Boats in general and fishing boats in particular are a lesson in compromise.
Fishing boats are a compromise because no single boat design or model is capable of performing flawlessly at the many ways anglers target fish. Case in point, that sleek and speedy bass boat hull that’s ideal for chasing largemouth on in-land bodies of water, is about worthless for trolling up salmon with downriggers on the big pond.
MULTI-SPECIES OR MULTI-PRESENTATION?
Some boats are made to be compromises like the always popular multi-species hulls. It’s true that multi-species models are designed with an eye toward versatility. The multi-species concept is a solid concept for the angler who wants to fish a wide variety of species, but even this boat type has short comings....
For those who love to troll for trout, salmon, steelhead and walleye, three words should be on your lips at every fishing adventure.
Finding fish is fundamental to fishing success, yet it amazes me how ill equipped many anglers are when it comes to using sonar effectively. Sonar technology has so rapidly evolved in recent years, that it’s surprisingly easy to find yourself using flip phone technology in a smart phone world!
If you are one of those “flip phone” guys, it’s time to dig in and educate yourself on the advancements of modern sonar. While traditional broad beam sonar is still the primary tool used to locate open water species, if your sonar is not equipped with something called “chirp” technology you are not seeing the full picture. Chirp sonar is a multi-signal version of broad beam that delivers much greater detail and more precise target separation than po...
