Castable fish finders can be used for fishing from shore, boats, and ice.

Because it uses your smartphone’s screen as its screen, the screen does not exist. Is that weird? It’s not at all. After connecting to your smart phone via Wi-Fi, it displays information on both Android and iOS. It doesn’t require any cellular data so you can use it without interruption.

It also allows you to save, review, and analyze your maps right from your bed, thanks to its GPS. You can create bathymetric maps right from shore and get free access to Lake book which is Deeper’s bathymetric management platform.

It can scan down to 260ft, so it doesn’t scan very deep. It has a great target separation of 0.5 inches and scans at around 15 scans per minute. It can be cast up to 330ft/100m.

Let’s now talk about the sonar. You can choose whether to use a narrow or wide beam. This is what kind of sonar? It is a dual beam sonar. This is the beauty of dual-beam sonars. Wide beams (90kHz 55deg), cover a larger area, but provide less detail. While narrow beams (290kHz 15,deg), give you a more detailed view of a smaller area.

It is easy to set up and doesn’t require cables. It is ideal for smooth trolling.


  • Castable
  • Dual beam sonar
  • Useful for ice fishing
  • Wi-Fi is preferred to Bluetooth
  • No cables are required


  • Battery with short-life

This fish finder is a great choice if you’re looking for a fishfinder that costs less than $500 and has Down Imaging and dual-beam sonar.

If you’re looking for one that has a dual beam sonar, I assume you already know the purpose of it. But I will tell you. Dual-beam sonar allows you to choose between narrow beam and wide beam.

Although the narrow beam can be useful for scanning small details, it cannot scan large areas. A wide beam, on the other hand scans large areas but doesn’t provide much detail.

The Dual Beam Scan’s impressive features are limited. It only allows for one frequency per scan, while the Dual Beam Plus scan lets you use multiple frequencies at once.

The down imaging sonar has a 2D depth of 600 feet (200 KHz) and a DI depth of 320 feet (455 KHz). It provides a detailed view of the area below your boat.

It’s also quite powerful with 2400 watts peak to peak and 300 Watts RMS.

It comes with tip 2.5’’ target separation to detect fish from the general vegetation.

It also has an XNT9 Di T transducer with a water-temperature sensor. The transducer can be mounted on the transom. It can be used to scan the water for fish, or even target them.

It boasts a 4.3″ color LCD screen display with 256 colors. It features a resolution of 272H X480V pixels and is easy to read in sunlight due to its LED backlight.

As life has shown us, there is no perfect solution. It doesn’t include a CHIRP Sonar, which some users consider essential. It does not have a GPS or other navigation functions.


  • Features Down Imaging
  • Uses the Dual Beam Sonar function
  • The screen displays 256 colors
  • Is equipped with an XNT9 Di T transducer


  • No CHIRP sonar technology
  • Navigation features are missing
  • No Dual Beam Plus scan function
  • Chartplotter is not required

Bottom line

Although this fish finder lacks certain essential features, such as a navigation function or CHIRP sonars, it still offers a lot. It has impressive features like a dual beam scan, a down imaging scan, and the ability to measure water temperature.

What to look for when buying a fish finder?

You must be clear about what you want before you buy anything. It is not a good idea to just buy anything, only to find out later that it is junk. We have chosen to share with you the most important features of a fishfinder. You will need to decide which one is more important to you.

1. Frequency

Every fish finder has its frequency. It is determined by its frequency. Most people believe that the higher frequency is better. You aren’t wrong but you don’t know everything. It isn’t a puzzle.

Frequency transmits waves into water and returns information about what’s under the water. It is important to remember that lower frequencies transmit wider beams while higher frequency emits narrower beams.

Fishing in deep water requires a fish finder that scans deeper. However, it will not scan large areas.

If you have to scan large areas, choose one that has high frequency.

2. Power

The faster the information appears on the screen, the more wattage you have. It also reduces the time it takes to respond.

3. Transducer

This is due to the frequency at which the transducers emit sound waves into water. The wider beam scans large areas, while the narrower scans deeper.

Because it emits sound waves in a cone-shaped pattern below the water, it is closely related to the cone angle. The beamwidth is usually between 9 and 60deg. A cone angle of 20deg is great for fishing at different depths.

4. CHIRP Sonar

A CHIRP Sonar technology is a compressed high-intensity radio pulse. CHIRP Sonar technology is superior to traditional ones as it transmits a continuous range at the same frequency. This allows for clearer images and higher resolution.

5. Water Resistance

Make sure your fish finder is not damaged by water. It’s obvious that fish finders will come in contact with water, and could get wet. Go for an IPX7 fish finder.

6. Screen Resolution and Size

What good power and frequency would do if the screen has poor resolution and is small? They would be useless. High resolution screens will always be better as they show more detail.

A screen size that is suitable for your workspace is important. A large screen may not be a good idea for a kayak that is small.

7. Screen Color

A colored screen is better than one that only shows the information in black and white.

8. Chartplotter & GPS

Many people mistake a Chartplotter with a GPS. You must be aware of the differences between them. A Chartplotter lets you map the area around your location so that you can perform navigation. This allows you to see where you are relative to where you started.

GPS, on the other hand allows you to only mark waypoints.

What to Expect From a $500 Fish Finder?

For less than $500, you can get many features from some of the most powerful fish finders.

This list includes sonars with CHIRP, GPS, dual beam sonars, microSD cards, and others.

The bottom line is that a budget-friendly fish finder purchase doesn’t have to be difficult if you take into account the important features. Next, narrow down your choices and choose the one that suits you best.

Last Thoughts

I’m sure you have found the best fish finder for under $500. It is easy to find the best fish finder for you. It is as easy as prioritizing your needs and you will see which one suits you best.

We know how stressful and confusing it can be to purchase something on a limited budget so we’ll give you a brief recap.

Lowrance HOOK24X fish finder is the best choice if you want to save your waypoints or pinpoint fishing spots. It has a microSD card slot. It is also the most affordable. It’s also notable for its dual coverage, Solarmax display, ease-of-use, auto-tuning sonar and built-in mapping. It does not have a GPS.

Garmin Striker 4 may be the best fish finder if you have a deep concern about having your fish finder scan to very deep depths. It scans down to 1,600 feet freshwater and 750 feet saltwater. It also has an in-built GPS that allows you to mark up 5000 waypoints. Unfortunately, this would mean that you would have to sacrifice a Chartplotter or a large screen.
