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).
MOUNTING THE FISHFINDER: Cockpit space in any paddle craft is premium real estate, so definitely do some planning before you do some drilling. The carpenters pencil is your friend in this case. I suggest that before you drill/cut, you spend some time on the water and use that pencil to mark up potential mounting spots. You have to be able to see it well and to reach it, but it needs to be out of the way when you cast, land a fish, or get in/out of your boat. If your boat has some sort of console, that's an obvious mounting choice. But, if you don't then Ram Mounts offers a number of multi-position solutions that will allow you to mount it just about anywhere. Once you decide where it will go, you have to get the wiring to the battery and to the transducer.

There are plenty of different things you want to keep in mind while searching for the perfect GPS fishfinder for you. First, keep in mind that not all models are created equal. Some will clearly be more useful than others. You will also find that different boats call for different fish finders. Many times ditto depending on the style of fishing or information most important to you.
Pinpoint your favorite waypoints and track fish with a fishfinder from Academy Sports + Outdoors. With a detailed black-and white LCD display, you can clearly spot fish as deep as 1,000' as well as track their location with depth finder technology. Water temperature sensors allow you to monitor the biological patterns of prospective catches, letting you pinpoint where they'll be at any time of day. With a waterproof casing, our selection of fishfinders are designed for use on boats or kayaks. Our giant boating and marine shop has an assortment of marine electronics from popular brands, like Humminbird, Garmin marine and Lowrance, can help you reel in the largest catch. Receive notifications for certain depths and types of fish, as well as sonar and mapping software, so you can find exactly what you're looking for.
It’s no secret that HDS displays are used by more tournament fishing pros than all other fishfinding brands combined, so we didn’t have to go back to the drawing board to build it; we just made the best fishfinder/chartplotter in the world even better. HDS LIVE  delivers premium performance and support for the best collection of innovative sonar features available – from Active Imaging™, StructureScan® 3D, FishReveal™ and LiveSight™ sonar, to exciting navigation functionality like C-MAP® Genesis Live mapping – all designed to help you find more fish.
Other devices which are widely used as bite indicators are floats which float in the water, and dart about if a fish bites, and quiver tips which are mounted onto the tip of the fishing rod. Bite alarms are electronic devices which bleep when a fish tugs a fishing line. Whereas floats and quiver tips are used as visual bite detectors, bite alarms are audible bite detectors.
A GPS is a must have for many fishers and having it in one unit with a fish detector is economical, space saving and convenient. Having the addition of a GPS gives you many benefits. It will give you the ability to mark hot fishing spots and easily return to them in the future, as you can mark the spot on the GPS and then track your way back to it later. These spots are called waypoints and on most units you will be able to mark hundreds or even thousands of them.
Now let’s imagine another scenario – again your sonar is stationary, but this time 2 fish swim through your sonar beam, one big and one small. The big fish swims very quickly through the sonar beam, the small one swims slowly. Which one will make the longer fish arch on your screen? The answer is the small one. That’s because a slow moving object will leave a longer mark than a fast moving one, whatever their size.
Portable fish finders are the better choice for those who lease their boat. Also if you ice fish or “fly-in” fish, a portable unit would be more suitable for you. They usually come with their own carrying case and battery power supply. Most of the fish locators come with the transom mount for installation. The portable units come with the transducer already attached to the transom with the use of a suction cup.

The final point to remember when you are looking out for fish arches is that it doesn’t need to be a full arch. Half arches (like the ones shown in the screen shot above) also show that there is fish. In ourtutorial on how sonars work, we explain in detail why sometimes you get a full arch and sometimes you get a half arch. The short answer is that you will get a full arch if a fish swims through the whole of your sonar cone, and a half or partial arch if they only swim through part of it.

Do you prefer having more detailed and high-contrast visuals on your fishfinder? Color LCD options from Academy Sports + Outdoors can ensure you don't miss a single catch. With higher-quality screens, you can zoom into specific sections of the water and even target specific fish. With additional sensors, our collection of marine GPS can track the movement of fish in real time, allowing you to trail and snag them before they swim away. Academy also carries portable fishfinders as well as castable fishfinders which are great for kayak, surf or bank fishing.

However, fish finders for professional use, i.e., those used by commercial fishermen, can make use of other frequencies. Such frequencies include 15, 22, 28, 38, 45, 50, 68, 75, 88, 107, 150 and 200 kHz. There are some special fish finders that utilize the frequency of 400 kHz, but it is quite a rare case. As you can see, there is an extensive range of configurable frequencies available for fish finders for fishery vessels, and a fish finder generally makes use of a combination of two frequencies (high and low frequencies). The selection of the frequencies depends upon the intended purposes of the fish finder, which include, inter alia, finding specific fish species; grasping the seabed condition; conducting a wide-area-search with the search angle of 90 degrees at one go; conducting detailed search for fish schools; detecting fish schools that give weak echo returns; avoiding interference/conflict with other fish finders used nearby. The searchable range (depth) and search area are dependent upon the frequency used. On the one hand, high frequency ultrasound is suitable for a detailed search, although it cannot be used for search in deep water. Low frequency ultrasound, on the other hand, is suited for general searches in a wider area as well as searching in deep water.
