Higher frequency transducers have shorter wavelengths and more wave cycles per second, which means you can visualize more details (smaller fish) but have only shallow to moderate depth capacity. One sound wave at 200kHz is slightly longer than 1/4", so a 200kHz sound wave will be able to detect fish as short as a quarter of an inch. A 200kHz transducer has a range of only about 600'. High frequency provides a crisp, clear picture of the bottom with the tradeoff of less depth range. For best resolution, choose 800kHz or 455kHz transducers.

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.


Humminbird 140C Fishin’ Buddy is one of the top rated fish finders among the portable type. So you can use it on your boat, on the leased boat, on the dock or for fishing from anywhere else. To use the device you won’t need to do any rigging or wiring. Instead it uses extendable transducer tube housing with the length suitable for most small and mid-sized boats.

Winter weather may run us inside, but that doesn't mean the sport sleeps. Those "other things" I mentioned will be covered when I write my book, but for now they will have to wait. In the mean time, let's discuss some other "deep thoughts". Or should that be "thoughts about the deep"? Or maybe it would be "I thought this water was deeper". This article is about depth finders, or more commonly called "fish finders". In this issue, we'll discuss your options when it comes to selecting one of these gadgets, along with tips for temporary or permanent installation.


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.

The CHIRP sonar that is built into this model is second to none in terms of performance, and always gives you a clear picture and measurement of the floor and surface beneath your boat, as well as the location of the fish around it. Another feature that we really enjoy about this Humingbird fish finder is that it comes with a built in SD card slot so that you can save your favorite waypoints to it. You can even upload additional maps to your software using the SD card feature.


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.

It changed the game once. Now it’s poised to do it again. The HELIX Series has evolved, now offering MEGA Imaging+, Dual Spectrum CHIRP and Bluetooth connectivity in select models, along with exclusive technologies like Humminbird Basemap that you won't get from any other fish finder in its class. Power. Bold styling. Ease of use. In this family, the apple doesn’t fall far from the tree.

For just around 600 you can get this Raymarine Dragonfly fish finder that offers features that are usually found on much pricier models. It uses next-gen CHIRP technology that gives photo-like imagery with high resolution structure. The CHIRP technology transmits a wide spectrum of frequencies and the result is a much higher resolution. The generous size (5.7 inches) of the display gives an easy read of the underwater details and the 1600 nits gives clear viewing even in bright daylight.
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.
Choosing the perfect fish finder for your requirement is hard with many features such as imaging, power and more. The main purpose of a fish finder is to catch more fish with the screen displaying the fish and underwater structure and physical objects. Other information such as water temperature and depth are common on the majority of devices with many high end fish finders providing much more.
Commercial fishermen also make use of these characteristics. They conduct a search by low frequency (i.e., 15 kHz) beams first to grasp the general locations of fish schools around the boat. Subsequently, they narrow the search area for a fish school, using high frequency beams (200 kHz), to detect the exact location of the fish school and operate the boat to be directly above the targeted fish school.
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.

We’re only slightly kidding when we say that one of the simplest ways to pick a transducer is to decide just how big of a hole you want to drill in your boat. Fishfinders intended for the small-boat, freshwater angler often come with a transducer, usually a transom-mount type. But many transducers are purchased separately and need to be installed through the hull.
By calculating the amount of time between when the sound wave was sent and when it bounced back, it measures the distance and shows it on the screen. If the wave doesn’t encounter anything on its way, it reaches the bottom. If the bottom is soft and it’s just mud and weeds, the signal gets absorbed. A rock bottom will reflect a stronger signal back.
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.
BABY STEPS: You don't have to spend a ton of money or be an engineer to get your kayak electrified. Here we have the Lowrance X50DS. The fishfinder and the installation kit will run around $250. Look at what you spend for a rod/reel/braided line, and you'll find this kit is certainly affordable. The display is 4-level grayscale, and the battery pack contains AA batteries. However, what it may lack in fashion it makes up by function. The battery pack goes in a dry bag, and the unit itself is easily removed at the end of the day. It features a built in temperature sensor and 120 degrees of wide angle coverage.

Raymarine has a few units that come with a built in GPS. The Dragonfly 4Pro, Dragonfly 5Pro, and Dragonfly 7Pro all have built in GPS. Pay close attention to the unit you are buying, because if you are looking for built in GPS the standard Dragonfly 4 and Dragonfly 5DVS do not have that feature built in. You absolutely have to go Pro to make sure you get the GPS you’re looking for.
Screen Color & Resolution is an essential factor in your selection. Color screens are the new norm on today’s fish finders. A color screen enables you to more easily decipher objects in the water, giving you valuable insight into your game fish. Also consider the amount of pixels on your screen—the more pixels, the greater level of detail you can see. LED backlit screens provide brilliant visual display, particularly for fishing in low-light conditions.

Understanding how a fish finder works will help you to understand how to use it. Fish finders work using sonar. It’s a technology that uses sound waves to display underwater objects. The fish finder produces the sound wave and with the transducer sends it through the water. Penetrating the water deeper, the sound wave starts to spread in the form of a cone (commonly called a beam). As the wave encounters objects within this beam, it sends the signal back to the transducer.

The sound wave spreads as it gets further from the transducer. The wider the cone, the larger the coverage area, but the as the cone angle spreads, sensitivity diminishes. A 20-degree cone is considered a versatile angle for fishers who frequent different water depths. More advanced devices come with double and triple beams, ideal for scanning deep water depths.
Lowrance hds 7 gen 2 touch. Took it off my boat when I got low balled on price of boat.... I think it has less the an hour on it... I honestly dont remember using it at all. Regardless, it has very very low hours if it was used at all. No ducer, wire or mounts come with this. Buyer of my boat literally handed me cash that was 500.00 short so I took it, unplugged this and walked away. Perfect for someone that already has lowrance set up on boat. Selling with no reserve. So good luck.
Few things aggravate ice anglers more than frozen rod guides. Chipping away with fingernails, teeth, or anything else lying around can easily damage both the frame and rings of the guides, but you have to keep them clear because iced guides will weaken line, especially super-­light monofilament or fluorocarbon. There are a number of homebrew remedies for tackling this problem, but none are more effective than lip balm, which creates a film on guides that inhibits them from freezing and building ice. It’s waterproof and takes quite a while for wet line or precipitation to break it down and necessitate reapplication. A small stick or tin stores easily in your pocket, and just a few swipes with your finger on guide rings will protect them from ice-up for several hours.
Commercial and naval fathometers of yesteryear used a strip chart recorder where an advancing roll of paper was marked by a stylus to make a permanent copy of the depth, usually with some means of also recording time (Each mark or time 'tic' is proportional to distance traveled) so that the strip charts could be readily compared to navigation charts and maneuvering logs (speed changes). Much of the world's ocean depths have been mapped using such recording strips. Fathometers of this type usually offered multiple (chart advance) speed settings, and sometimes, multiple frequencies as well. (Deep Ocean—Low Frequency carries better, Shallows—high frequency shows smaller structures (like fish, submerged reefs, wrecks, or other bottom composition features of interest.) At high frequency settings, high chart speeds, such fathometers give a picture of the bottom and any intervening large or schooling fish that can be related to position. Fathometers of the constant recording type are still mandated for all large vessels (100+ tons displacement) in restricted waters (i.e. generally, within 15 miles (24 km) of land).
Paddling.net has always given me plenty of room to not only discuss paddle fishing things, but other worldly things as well. So, with colder weather upon us and fewer fishing opportunities available, I figured I might as well take full advantage of that luxury and devote an installment to those "other" things. You know, like politics, religion/faith (the huge difference between them), family, crime/punishment, and why Kiss still isn't in the rock and roll hall of fame.
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.

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.

The power of a fishfinder—the strength of the “ping”—is expressed in watts RMS (root mean squared). Power is directly 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.


Bait: If you're not using live bait or cut bait, you'll want to use artificial bait or lures. Most artificial lures resemble the type of bait fish or other food, such as worms or shrimp, that the fish you're trying to catch normally eat. These artificial baits can be scented and have metal spoons attached to them or be painted in metal flake to reflect light in the water. Other types of bait include jigs and jig heads, spoons, flies and spinnerbaits, which you can attach artificial or real bait to, and attractants to make artificial lures smell lifelike.
