Garmin Striker Vivid 4cv
In the second part of 2020, Garmin released a new series of Striker fish finders, the Vivid series. These basically offer the same features as the Plus units, but with 7 new added color modes for the ClearVü mode. These can actually be quite helpful as certain submerged objects or structure can appear differently depending on the color palette used.
The Striker Vivid 4cv is one of the smallest Garmin fish finders at the moment. It features a QSVGA color display with a pixel matrix of 272H x 480V. It has LED backlight for improved readability in direct sunlight and is IPX7 waterproof. It comes with a standard tilt-and-swivel mount, while the transducer has a transom mount. It does not have networking features and also does not have a microSD card slot.
The unit supports multiple base frequencies, including 50/77/200 kHz for standard CHIRP sonar, and 260/455/800 kHz for ClearVü sonar. This being said, you can pair it with different transducers, including the 50 kHz capable ones. However, it does not support Panoptix sonar or SideVü sonar.
The transducer included with the Striker Vivid 4cv is the classic GT20 model. This transducer uses two conical beams for standard CHIRP. Their coverage is 15° @ 200 kHz, and 45° @ 77 kHz, with the maximum possible depth capability of 1,900 ft. (579 m). For ClearVü, it also uses two beams, but they are oval, not conical. Their coverage is 53°x2.5° @ 455 kHz and 29° x 1.6° @ 800 kHz. The maximum depth capability is 750 ft. (288 m) for the 455 kHz beam.
The Garmin Striker units are not pre-loaded with charts and do not support any charts. The Striker Vivid 4cv is no exception. However, it does have a basic GPS plotter and has Quickdraw Contours. This is a bathymetric mapping feature that uses the GPS data and the sonar data to reveal and record the depth contours of the lake that you’re scanning. It also has Depth Range Shading. Plus, it offers the possibility to record tracks, create routes, and save waypoints.

Humminbird Piranhamax 4 DI
The PiranhaMax 4 DI is one of the oldest, most popular, and most affordable Humminbird fish finders. Although it’s one of the models released in 2016, it’s still available in 2023. It’s one of the Humminbird models without GPS and maps. For reference, this is the Humminbird unit part number 410160-1.
The PiranhaMax 4 DI offers two sonar technologies. These are standard DualBeam sonar and Down Imaging. It does not have CHIRP technology. It supports two frequencies, these being 200 kHz and 455 kHz. The DualBeam sonar can use both these frequencies, while the Down Imaging sonar operates only at 455 kHz. The unit does not support 83 kHz or 50 kHz.

Humminbird HELIX 5 DI G2
Although it’s one of the Humminbird fish finders released in 2016, the HELIX 5 DI G2 is still available in 2023. It offers a similar range of features to the PiranhaMAX 4 DI, but has a 5-inch display, with a pixel resolution of 800 x 480. Since it’s a G2 unit, its interface is slightly different, more user-friendly than the interface of the previous model.
The HELIX 5 DI G2 does not have any navigation features. It’s a sonar-only fish finder. It offers standard DualBeam Plus sonar and Down Imaging sonar. It also does not have CHIRP technology like the newer units.
The unit comes with the XNT 9 DI T transducer which uses two conical beams for standard sonar, and two thin beams for Down Imaging. The beams of the standard sonar offer a coverage of 28° @ 200 kHz, and 16° @ 455 kHz. The Down Imaging beams have angles 75° @ 455 kHz, and 45° @ 800 kHz. The maximum depth range is 600 ft. (183 m) for standard sonar, and 350 ft. (106 m) for Down Imaging.
The HELIX 5 DI G2 offers most standard sonar features available with the more expensive 5-inch Humminbird units. To begin with, SwitchFire and Selective Fish ID are available with the DualBeam Plus sonar. SwitchFire is a quick filter which gives you access to a Clear Mode and a Max. Mode. The Clear Mode removes most of the clutter an insignificant targets, leaving only the biggest targets on the display. This way, you can immediately see the bigger fish. Conversely, Max. Mode brings on the full information provided by the transducer, showing even the smallest targets. The Selective Fish ID feature essentially replaces the targets interpreted as fish, with fish icons and can show the exact depth of each fish next to it.
A classic Gimbal mount is included with the unit. However, there is also the option of an in-dash mounting kit. The box does not include a unit cover.

Deeper Pro+ Smart Sonar
The Deeper Pro+ Smart Sonar is not exactly your standard fish finder. That’s because it does not include a control unit. All the sonar elements are encased in a spherical shell made of tough plastic. It is intended for use with a smartphone and is castable with a fishing rod. It connects to your smartphone (or tablet) via the Fish Deeper app available for iOS and Android.
The Fish Deeper app has a pretty versatile interface. It has quick launch buttons for the phone’s camera (which is quite neat if you want to quickly snap a photo of a fish you caught), calendar, maps, weather, settings, and others. It also has a split-view function so you can see both the sonar and the bathymetric mapping in the same window, in split-screen.
The Deeper Pro+ sphere integrates a dual-beam 15°/55° transducer. Its maximum depth capability is 260 ft. (80 m). It also has a pretty decent WiFi range; it should be able to send data to your smartphone in a range up to 330 ft. (100 m).
Internal GPS and a bathymetric map creation function are also available with this fish finder. This being said, you can create your own custom maps for your fishing spots with the most up-to-date depth contours.
Last but not least, the unit features a USB port concealed by the top cover of the spherical shell. It can be charged via USB cable with a smartphone charger or from a PC. It also comes with a portable bag.

The fishing line to which it is attached may snap and you can lose your Deeper Pro+ or it may be difficult to retrieve. |
Vexilar SP200 T-Box
Although Vexilar is known specifically for its ice fish finders, they also offer a model that is similar up to a point to the Deeper Pro+ model. That is the Vexilar SP200 T-Box. However, it is not a castable model like the Deeper fish finder. It includes a conventional dual-beam transducer and a small sonar black box. The sonar black box also has an internal WiFi module so it can connect to your smartphone or tablet via the free SonarPhone app available for iOS and Android phones.
The SonarPhone app offers a pretty wide array of fish finding features, including fish icons, bottom zoom, noise rejection, surface clarity, automatic range, fish alarm, and more. It can also run both beams of the transducer simultaneously. Unlike the Deeper Pro+ app, it does not have a map creation function. However, it is compatible with the Navionics app. Therefore, if you install the Navionics mapping app, the SonarPhone app can work with it so you can view the sonar and the maps in split-screen.
The transducer included with the Vexilar SP200 uses the 200/83 kHz frequency channels. It casts two conical beams with a coverage of 20° @ 200 kHz, and 40° @ 83 kHz. The maximum depth range is 240 ft. (73 m) and can be achieved by the 83 kHz beam. Also, the WiFi range of the small black box is approx. 300 ft. (91 m). The transducer comes with a transom mount and also has an internal temperature probe.

Deeper PRO+ 2 Smart Sonar
The Deeper PRO Plus 2 is one of the fish finders released in 2021. It’s basically a newer version of the Deeper PRO+ which essentially has the same features but comes with a triple beam sonar system. For reference, this is the Deeper smart sonar part number DP5H10S10.
The fish finder itself has the same construction as the previous model. It is encased in a spherical shell made from a durable thermoplastic material, black in color. Since it’s a castable fish finder, it does not come with a head unit. It connects to your smartphone via Wi-Fi (not Bluetooth) and has a broadcasting range of 330 ft. (100 m).
The connection between the Deeper PRO+ 2 smart sonar and your phone is mediated by the Fish Deeper app. It offers a wide variety of standard sonar features such as fish symbols, A-Scope, Circular Flasher, and more. It also offers features such as a calendar, shortcut to the phone camera for a quick selfie with your catch, temperature reading, self-adjusting depth scale, and more. It’s also important to mention that now the app also has a premium mode with extra features such as 50,000 fishing spots marked on maps. The Fish Deeper Premium comes with a free 3-month trial for the PRO+ 2.
The unit’s transducer casts conical beams. Their coverage is 7° @ 675 kHz, 20° @ 240 kHz, and 47° @ 100 kHz. The maximum depth range can be achieved with it is 260 ft. (80 m). Also, it offers a better target separation than the older model, 0.4″ (1 cm) down from 1″ (2.5 cm).
In terms of navigation, the unit has internal GPS and supports GLONASS, Galileo, BeiDou, and QZSS as well. Plus, the app has a bathymetric mapping feature that allows you to map your own lake with the most up-to-date depth contours, and mark your favorite fishing spots on the maps.

What to Look for When Choosing Your Fish Finder
Needless to say, the 10 fish finders that we’ve covered here may not be all the models available under $300. Therefore, if you’re looking for affordable fish finders, here are a few aspects to consider.
Brand
Some of the most popular fish finder brand names at the moment are Garmin, Humminbird, and Lowrance. They pretty much offer fish finders from the most basic models to the most inclusive and most advanced. Some of their most affordable models are actually covered on this page. However, even their most basic units may cost a little extra due to the brand name’s popularity. So, if you only want a basic fish finder that costs under $300, you should also check some of the less popular brands such as Phiradar, for example.
Sonar
Most basic fish finders offer only one type of sonar, typically standard sonar with or without CHIRP technology. Of course, there are exceptions as well. For example, the PiranhaMax 4 DI, or the Garmin Striker Vivid 4cv are some of them. These also have down-scanning sonar. It is also a plus if a fish finder can support dual-frequency, as not all have this feature. This means that the unit can work with two sonar frequencies simultaneously and you can view the returns from two transducer beams in a split-screen.
Transducer
A transducer is not always included with a fish finder, but there are quite a few models under $300 that do include one. It’s definitely a plus to have a full fish finding system out of the box and not have to look for a compatible transducer once you’ve got your unit. Also, you can be sure that the transducer included with your fish finder is compatible with it. All the fish finders on this page include a transducer
Navigation Features
If you’re looking for an affordable fish finder, chances are you may not need GPS and charts. However, in case you do, there still are several models under $300 that include features like this. For example, the ECHOMAP Plus 43cv is one of the most complete models in this category offering standard GPS and the LakeVü charts. Also, units like the Lowrance Hook Reveal 5x, or the models in the Garmin Striker series, have basic GPS and a bathymetric mapping feature such as Genesis Live or Quickdraw Contours.
Networking Features
Again, if you’re looking for an affordable fish finder, you may not need networking features such as NMEA support, Ethernet, or online connectivity. Most models in this category don’t have these features. The only model under $300 that we could find, that actually supports NMEA 0183, is the ECHOMAP Plus 43cv.
Final Word
The fish finders that we’ve covered here are some of the best under $300 available in 2023, at least for the moment. Our top 10 covers models for all budgets and needs. Each one comes with a transducer, and most of them offer at least dual-beam sonar. They all offer excellent value for the price, and so far, most of them have gathered the best user feedback.
