Garmin Striker 4
Although the Striker 4 010-01550-00 is one of the first Garmin fish finders of the Striker series 
(released in 2015), it still is one of the most popular models at the moment. That’s because it’s the most affordable unit and pretty much offers an excellent price/quality ratio.
The Striker 4 is equipped with a 3.5-inch color display, featuring a pixel matrix of 480V x 320H and LED backlight for superior readability. Its waterproof rating is IPX7 which essentially means that it can withstand incidental water exposure. It does not have Wi-Fi or other networking features and comes with the standard tilt-and-swivel mount.
This Garmin fish finder does not have, nor it supports ClearVü sonar. It only has standard CHIRP sonar. It supports three base frequencies, these being 50/77/200 kHz. It also supports dual-frequency. It makes available several standard sonar features such as Fish Symbol ID, A-Scope, Ultrascroll, Auto Gain, Flasher, Split-Zoom, and several alarms.
The transducer included with the unit is the Garmin 010-10249-20. It’s a dual-beam transducer that supports 77/200 kHz. Evidently, it does not support ClearVü. It casts two conical beam, one of 45° @ 77 kHz, the other of 15° @ 200 kHz. The 77 kHz beam has the greatest depth range; it can scan depths up to 1,900 ft. (579 m). The transducer comes with a transom mount, 20 ft. (6 m) of cable, a 4-pin connector, and has an internal temperature sensor.
The Garmin Striker 4 fish finder is not a full chartplotter but does have basic navigation features.

Garmin Striker Plus 4
The Striker Plus 4 010-01870-00 is currently one of the most affordable Garmin fish finders. Although it is one 
of the units released in 2018, and the newer Vivid series was already released it is still available at the moment. It only has CHIRP sonar, the basic GPS plotter, and the Quickdraw Contours feature.
Since it’s one of the most basic Garmin fish finders, the Striker Plus 4 does not support SideVü, ClearVü, or Panoptix sonar. However, it does support four frequencies for its standard CHIRP sonar, these being 50/77/83/200. The CHIRP intervals may vary depending on the transducer. The unit also supports dual-frequency. Thus, if you pair it with a dual-beam transducer, it can use both beams at the same time and you can view their returns in split-screen.
The unit comes with the standard Garmin dual-beam transducer that supports 77/200 kHz. It’s a plastic transducer, has 20 ft. (6 m) of cable, with a 4-pin connector. It is also temperature capable.

Buyer’s Guide for the Best Garmin Fish Finders
As we’ve mentioned above, Garmin releases at least a few new fish finders, if not a whole series, every year. However, not all of them are well-received and not all of them may fit your needs or budget. Therefore, here are a few things to consider if you want to end up with one of the best Garmin fish finders.
Fish Finder Series
So far, Garmin has released several chartplotter and fish finder series. These are GPSMAP, ECHOMAP, and Striker.
GPSMAP series. The Garmin GPSMAP units focus on offering a wide array of navigation features and networking possibilities. All of them support Radar but not all of them have built-in sonar. Most do support sonar, though, if they are connected to a GSD or GCV Black Box sonar module. So, these being said, the GPSMAP models are multifunction boating instruments, rather than fishing tools. They’re also quite a bit more expensive, in general, than the units of the other Garmin series.
ECHOMAP series. The Garmin ECHOMAP series offers mid-range fish finder and chartplotter combos. They all have standard internal GPS and are pre-loaded either with the LakeVü maps or the BlueChart maps. These don’t support Radar but do offer NMEA networking possibilities and wireless connectivity. The most recent models of this series are the ECHOMAP UHD and the ECHOMAP Ultra, which have replaced the older ECHOMAP Plus and ECHOMAP CHIRP.
Striker series. The Garmin Striker series includes the most affordable Garmin fish finders. These don’t support charts but do have a basic GPS plotter and the Quickdraw Contours feature. They’re pretty much focused on sonar features rather than navigation features. They don’t have NMEA ports or Ethernet, but the 7-inch and 9-inch models do have wireless connectivity.
Types of Sonar
Currently, there are four main sonar technologies offered by Garmin. These are traditional CHIRP, ClearVü, SideVü, and Panoptix. Depending on unit, these are available in various combinations. For example, the most affordable models, like the Striker Plus 4, only have traditional CHIRP sonar while at the opposite point of the price chart there are models like the ECHOMAP Ultra 126sv which have all the sonar technologies.
Now, depending on the fishing method that you’re using, or the fish that you are looking for, some sonar technologies may be considerably more useful than others. For example, if you’re looking for structure, or bass that might be hiding near structure, DownVü sonar is great. If you’re looking for pike stalking prey near-surface and rely on long lure casts, SideVü will definitely make a difference. And finally, if you want to view real-time lure and fish movement, Panoptix sonar is definitely the sonar technology that you should opt for.
Supported Frequencies
Most Garmin fish finders support at least 77/200 kHz for traditional sonar, and 455/800 kHz for structure scanning sonar such as ClearVü and SideVü. If you’re fishing on lakes that aren’t too deep, the supported frequencies shouldn’t matter that much because with any transducer, you should be able to scan depths of at least a few hundred feet. However, if you’re fishing off-shore, you should definitely opt for a unit that supports 50 kHz for traditional sonar, and 260 kHz for structure scanning (ClearVü). A transducer/unit combo that supports these frequencies should be able to scan depths greater than 2,000 ft.
Transducers
Most Garmin fish finders come with at least one transducer. The most common model included with at least a few units is the GT20-TM. This transducer supports 77/200 kHz for standard CHIRP and 455/800 kHz for ClearVü (does not support SideVü or Panoptix). Of course, each unit is compatible with at least a few transducers. So, in case you are thinking of a future upgrade, you might want to check the transducer compatibility of the unit you’re looking at.
GPS and a decent chart platform are great features to have in a fish finder. They can be quite useful especially if you’re fishing off-shore or on a large lake. All Garmin units starting from 2018 have at least a basic GPS plotter and the Quickdraw Contours feature. If you don’t want to spend on navigation features, the Garmin Striker units are the ones to put on your list. However, if you’re looking for superior navigation features, then you should opt for either a GPSMAP model or an ECHOMAP model. These have at least a 5 Hz internal GPS, and at least LakeVü g3 or BlueChart g3 maps. They are also compatible with their superior versions, LakeVü g3 Ultra, and BlueChart g3 Vision.
Other Included Accessories
Garmin fish finders are available in various bundles. Some include more than one transducer. Especially the ice bundles come with the carrying case, battery, and charger. Even though a bundle like the Garmin 010-01893-21 is intended for ice fishing, it can still be adapted for boat or kayak fishing. Also, accessories such as a unit cover, flush mount, or trolling mount for the transducer can always be useful when on the water, so if there’s a version that includes them all, it’s not a bad idea to go for it.
Final Word
Garmin offers a wide selection of fish finders; some are greater than others and benefit from a considerably higher popularity among anglers. Our page here brings to view the top 10 best Garmin fish finders for 2021. All the models here have an almost clean 5-star rating on all retailer websites. They also cover a wide range of prices, from the most affordable ones to some of the most expensive. Therefore, if you’re looking for a Garmin fish finder, at least one on this list should fit your needs and your budget.
