Finally, we come to the HDS-7 from Lowrance. I have had limited experience with this company, but from what I know it is a fantastic maker of fish finders, and the HDS-7 is no exception. This particular model has a seven-inch touchscreen, which makes it one of the most high-tech options you can find anywhere. If you like a more ergonomic design and want something that is more user-friendly, the HDS-7 could be for you.
Transmit Power: Transmit power is expressed in watts RMS (root mean squared) and is related to how well you see in silt-laden water, view down to greater depths and successfully resolve separate targets and bottom structure. A 500-watt (RMS) fishfinder should have plenty of power for most coastal applications. Serious bluewater anglers should look for 1,000 watts or more. Inland lake fishermen can see the shallow bottom with only 200 watts.
A fish hook is a device for catching fish either by impaling them in the mouth or, more rarely, by snagging the body of the fish. Fish hooks have been employed for millennia by anglers to catch fresh and saltwater fish. Early hooks were made from the upper bills of eagles and from bones, shells, horns and thorns of plants (Parker 2002). In 2005, the fish hook was chosen by Forbes as one of the top twenty tools in the history of man.[2] Fish hooks are normally attached to some form of line or lure device which connects the caught fish to the angler. There is an enormous variety of fish hooks. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. They are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, processed, dead or live baits (bait fishing); to act as the foundation for artificial representations of fish prey (fly fishing); or to be attached to or integrated into other devices that represent fish prey (lure fishing).
The intensity of the sonar return from a hard bottom will be different to one from a hard bottom. Your fish finder uses colour to show this difference. In the standard colour palette of the Deeper display, the colour varies from dull brown (softest) to intense orange (hardest). In the day mode colour palette (see screen shot), the difference is even easier to see, with the colour ranging from purple (softest) to red to orange to yellow (hardest).
The most common mistake anglers make when reading their fish finder is thinking that a long arch means a big fish. This is not the case. On your sonar display, you should think of length as representing time. For example, imagine you keep your fish finder stationary in the water (in other words you are not reeling or trolling it). If there is a fish underneath that is also stationary, what will you see on your fish finder display? You will see one continuous line. That doesn’t mean there’s a blue whale stranded in the pond you’re fishing. It means there is a stationary fish under your fish finder, and it might be a very small one.

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.
These are very valuable features to target for a range of species, and the good news is, they are easy to spot with a fish finder. As you troll or reel in your device, you will see the depth contour change – don’t forget to use the depth reader on your display (on the Deeper App it’s in the top right corner of the screen) so you can track how quickly the depth is rising or falling.
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).

Hello there! My name is Rick and you’ve probably come across my website because you’re in search of a product that will make your fishing experience easier and more effective. Or maybe you are just looking for information to get a better understanding of fish finders. In any case, you’ve come to the right place. I’m not a professional in this industry, I’m just a fishing enthusiast and during my search for the best fish finder on the market I’ve learned quite a few things about them. To give you the benefit of all the research I’ve done, I’ve created this website.
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.

Your fishfinder needs to accomplish two objectives: find the fish and help you record where they like to hide at your favorite fishing spot. In both respects, Garmin’s Striker 7SV definitely delivers the goods and then some. This superior scanning sonar gives one of the most complete images available of what is in the water around you and how deep the fish are hiding in real time with near-photographic detail. In terms of an easy to use interface, this model uses dedicated navigation and function buttons to provide reliable responses for more intuitive operation even by novice users.
For precise detection of structures and fish, our Raymarine radar bundle gives you remarkable resolution. The Garmin Chartplotter radar combo updates your position 10 times per second to accurately maintain your heading. A large screen with an outstanding LED display on our Humminbird fish finder GPS provides images that are easy to read even in bright sunny conditions. You can find the best marine depth finder GPS combo here, and we stand behind all of our products with a 30-day guarantee against defects. Contact our team of experts if you should need any assistance in finding the products you require.
Fish will show up on your screen as an arch (the reason why they are shown as an arch is explained in detail here). But it’s important to remember these arches can vary in size (length and width), and might not be a full arch – look out for those half arches too. The screenshot below gives some nice examples of different arches. They vary in length and width, and some are not full arches, but these are all fish.

Modern lines are made from artificial substances, including nylon, polyethylene, dacron and dyneema. The most common type is monofilament made of a single strand. Anglers often use monofilament because of its buoyant characteristics and its ability to stretch under load. Recently alternatives such as fluorocarbon, which is the least visible type, and braided fishing line, also known as 'superlines' because of their small diameter, minimal amount of stretch, and great strength relative to standard nylon monofilament lines.
