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.
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.

The image above, at right, clearly shows the bottom structure—plants, sediments and hard bottom are discernible on sonar plots of sufficiently high power and appropriate frequency. Slightly more than halfway up from the bottom to the left of the screen centre and about a third away from the left side, this image is also displaying a fish – a light spot just to the right of a 'glare' splash from the camera's flashbulb. The X-axis of the image represents time, oldest (and behind the soundhead) to the left, most recent bottom (and current location) on the right; thus the fish is now well behind the transducer, and the vessel is now passing over a dip in the ocean floor or has just left it behind. The resulting distortion depends on both the speed of the vessel and how often the image is updated by the echo sounder.
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.

If I'm scouting a new area I won't know anything about what sort of structure is ahead until I paddle over it, blowing out any fish that may have been there. With this little guy, I could cast it to the spot, get a read on what's below and proceed. And, you have the luxury of retrieving it slowly to see bottom contours between you and that fishy spot. There have been a number of occasions when I've made numerous casts at a fishy looking location (without any luck), only to paddle over there and discover that it was 10" deep, nobody home.

Ultrasound frequency used by a fish finder generally ranges from 15 kHz to 200 kHz. However, the majority of the conventional fish finders oriented for recreational craft utilize 50 kHz and 200 kHz. Such fish finders available in the market incorporate electronic circuitry that can transmit and receive ultrasound in these two frequencies. Also, a transducer mounted on the bottom of the craft is configured to handle these two frequencies.
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.
A GPS also gives you navigation through the waters. For this you will need to select a unit that comes with background maps and charts. One more benefit of the addition of the GPS is safety. Wherever you fish, you will have the confidence that at the end of the day the GPS will easily point you home. For example, you could be fishing throughout different locations during the day, or you could lose sight of land, or some severe weather could suddenly roll out. In such situations, a GPS will give you the exact direction to your home and will tell you how far it 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.

Fly fishing tackle is equipment used by, and often specialised for use by fly anglers. Fly fishing tackle includes fly lines designed for easy casting, specialised fly reels designed to hold a fly line and supply drag if required for landing heavy or fast fish, specialised fly rods designed to cast fly lines and artificial flies, terminal tackle including artificial flies, and other accessories including fly boxes used to store and carry artificial flies.


The common earthworm is a universal bait for fresh water angling. In the quest for quality worms, some fishers culture their own worm compost or practice worm charming. Grubs and maggots are also considered excellent bait when trout fishing. Grasshoppers, flies, bees and even ants are also used as bait for trout in their season, although many anglers believe that trout or salmon roe is superior to any other bait. Studies show that natural baits like croaker and shrimp are more recognized by the fish and are more readily accepted. A good bait for red drum is menhaden.[5] Because of the risk of transmitting whirling disease, trout and salmon should not be used as bait.
When it comes to fish finders and fishing GPS technology, the HELIX 5 delivers some of the best in functionality and creating a seamless user experience for fishing pros and hobbyists. This unit uses precise broadband CHIRP, a Reflex interface, imaging sonar and the power to chart and create maps using Auto Chart Live. The HELIX 5 has taken what is already a premier fish finder tool, and taken it to new heights in terms of features and creating an even better user interface. The display looks rich and clear, and is powered with 4,000 watts of PTP power output.
The best value fish finder models that we have listed above are the most popular in 2014. All of them have high fish finder ratings and predominantly positive reviews of the users. According to your needs, one model or other might be a better choice for you. When you compare fish finders, you should consider your budget and the features you would like the fish finder you are looking for to have. Before choosing fish finder, you need to decide do you need a portable unit or a fixed one for mounting onto your boat. Also consider will a fish finder be sufficient for your needs or do you also need an integral GPS in the unit. We hope that with the information that I have provided in this best fish finder reviews, you will find a fish finder that will help you catch more fish.
Early sporting fathometers for recreational boating used a rotating light at the edge of a circle which flashed in sync with the received echo, which in turn corresponded to depth. These also gave a small flickering flash for echos off of fish. Like today's low-end digital fathometers, they kept no record of the depth over time and provided no information about bottom structure. They had poor accuracy, especially in rough water, and were hard to read in bright light. Despite the limitations, they were still usable for rough estimates of depth, such as for verifying that the boat had not drifted into an unsafe area.
Setting your tip-up baits at the proper depth requires a little work. Then every time you catch a fish or check your bait, you need to reset them. If you’ve got a few nickel-size buttons, those resets become no chore at all. Start by running your main line through one hole in the button and out another. This should allow you to move the button up and down the line easily, but provide enough tension to stop it from sliding on its own. Next, attach your egg sinker, barrel swivel, leader, and hook to the line. Once your depth is set, simply slide the button down to the water’s surface, and then reel the button up to the tip-up’s line guide. Now every time you reset your line after catching a fish or changing bait, wind the spool until the button is at the tip-up guide. Your bait will be set in the same place within the water column every time.
Another great feature of the Elite-5X HDI is the Downscan Overlay that combines traditional sonar with Downscan. Downscan’s primary purpose is finding structure, but it can’t very accurately spot individual fish. That is better done by sonar. Combining the two in one, this device displays on one screen both bottom and structure. So you can see every rock and submerged object as well as fish.
As you look for a GPS/fishfinder combo, keep in mind that the best power and frequency won’t mean much if you can’t use the information. Think in terms of a computer. You can have the most-powerful and efficient computing capability, but without a high-quality monitor, the data does you little good. That’s why it’s always a good idea to spend a bit more to get a top-shelf screen.
As we mentioned, the strength of a fish finder is in how well it can locate the fish, which is why you need a high-quality transducer. CHIRP technology is one of the best you can find, and it provides a 200-watt RMS signal that can reach down to 1,600 feet in fresh water and 750 feet in salt water. Overall, you can find plenty of fish with this device.
Networked system: Fully networked systems are available from all the major suppliers, and usually will support a huge range of data sources including radar, raster and vector GPS charts, video, and SiriusXM satellite radio. Many allow Bluetooth/WiFi, and you can control them from your iPhone or Android smartphone. Your fishfinder, often an external “black box” module, is just one of these sources of data. Multiple-display network systems are great for medium-sized or large vessels. Capabilities get more amazing every year.
