Points are more gradual than drop offs, but spotting them is just as easy (see the screen shot below). Make sure you maintain a steady speed when trolling or reeling so you get an accurate reading on how steep the incline is. You should scan with a narrow sonar beam to get the clearest reading, and to ensure you see any shelfs or humps which wider beam scanning might not pick up (our page onhow sonars workexplains why this is).
To get the most of the both there’s the dual beam type of transducers. It’s also called dual frequency and which combines both features in one unit. Other types of transducers are more specialized. They include multiple beams (can be 4 or more). These cover a larger area of the underwater and can even give a 3D image on the display. One more option is the side beam transducer. These units shoot their signals to the sides, which increases the search area for fish.

The use of the hook in angling is descended, historically, from what would today be called a "gorge". The word "gorge", in this context, comes from an archaic word meaning "throat". Gorges were used by ancient peoples to capture fish. A gorge was a long, thin piece of bone or stone attached by its midpoint to a thin line. The gorge would be fixed with a bait so that it would rest parallel to the lay of the line. When a fish swallowed the bait, a tug on the line caused the gorge to orient itself at right angles to the line, thereby sticking in the fish's gullet.

Multiple Charting options from Insight, Navionics and C-Map enable the Simrad GO5 to go anywhere the water takes you.
In summer and winter, water temperature is very important - these units will help you discover areas that should be comfortable for your target species. Safety is found in structure, for prey and predator alike. The illusion of safety for baitfish equates to food for prey. So locating proper structure is certainly important. It's been said that 90% of the fish can be found in 10% of the water. Believe it. If you're fishing structure in the middle of a lake or a man-made reef, knowing what's below you is important. Now you know.
These units are battery operated and the signal is transmitted back to the receiver. So, don't expect a lot of range or HD resolution. But, if you simply want to know how deep the water is ahead of you so that you can make better choices, this is it. For me, I would need to cast it with a rod/reel loaded with heavy braid. The areas I'd likely cast to would hopefully hold big snook and in the spring they love this color. I don't want the "dog ate my homework" story to become the "snook ate my transducer" story.

Moreover, the 7SV also has a built in Garmin GPS that allows you to make your own waypoint maps, which makes marking all those stumps, docks, and brush piles as easy as clicking a button or two. All map information is transferrable to other Garmin fish finder devices if you upgrade as well, adding even more versatility to the 7SV. Additionally, the 7SV also has its own rechargeable battery pack that helps you stay on the water all day long, thereby increasing your chances of finally reeling in that trophy catch you’ve been looking for all these years.

Harpoons are spears which have a barb at the end. Their use was widespread in palaeolithic times.[11] Cosquer cave in Southern France contains cave art over 16,000 years old, including drawings of seals which appear to have been harpooned. Tridents are spears which have three prongs at the business end. They are also called leisters or gigs. They feature widely in early mythology and history.
