Best for Ice Fishing: Garmin Striker 4 with Portable Kit
Key Points at a Glance

- LCD Display Technology
- Ideal for Ice Fishing and Vertical Jigging
- Easy to mark, navigate, and view locations
- CHIRP Sonar Technology
Dimensions
- Item Weight: 8 ounces
- Dimensions: 3.6 x 1.6 x 5.9 inches
The Details
Simplicity is key when looking for a fishfinder, and the Garmin Striker 4 is designed just for that. It has a keyed interface with dedicated buttons. And it has a 3.5-inch screen with easy-to-read fonts while the color changes throughout the day.
It features an in-built flasher which is useful for vertical jigging or ice fishing. This allows you to see sonar data in a flashier format. For a long lifespan and increased durability, this device has standard quality components that are built to endure the longest trips.
Users will find it disappointing when attempting to position the Garmin Striker 4 on their boat. It’s only usable if it can be attached via kayak or boat. If this issue persists, we suggest getting a separate ice transducer.
The CHIRP Sonar technology is the Garmin Striker 4’s highlight feature. It allows anglers to find their target by sending a number of continuous frequencies underwater. It helps you get better views on the display screen while the GPS helps with tracking your current position.
For basic kayak fishing, the Garmin Striker 4 is a great option. It allows anglers to create waypoints, making it easier to keep track of fish that’s within their location. Since it is IPX waterproof, anglers will be able to use it to enhance their fishing experience. The Striker 4 was our favorite fish finder under $300.

Best Portable Fish Finder Buyer’s Guide
Who Should Buy a Portable Fish Finder
Novice anglers should consider a Fish Finder because it makes tracking potential targets far easier and allows you to focus on your individual approach. Previously, fishermen had to spend hours blindly looking for fish underwater or hoping there was fish present. With the help of fish finders, it displays the fish while you’re out, increasing your chances of finding that quality catch you can be proud of.
And if you’re a professional angler, fishfinders help with keeping track of your favorite locations. Some devices have a built-in GPS system, allowing you to save your favorite spots and return to them at a later date as well as find other’s favorite spots.
For ice fishing, it saves time by finding fish deep below, in some cases at depths of over 100 ft, allowing you to catch even the most elusive of prey.
Important Features to Consider
Water Resistance
If you’re going to mount your fish finder on an open finder, water resistance is necessary. Always check for the IPX or JIS ratings. While both ratings are interchangeable, each of them determines a unit’s level of resistance to water.
An IPX/JPS rating of 4 means it’s safe from water splashing, making it difficult to use on a kayak. With a rating of 5-6, it can withstand high and low-pressure jets of water. With a 7 rating, it can remain submerged underwater for about 10-30 minutes. 8 is the highest rating, meaning it can stay underwater for hours.
Power
Before buying any fish finder unit, you have to look at the power that it provides. If you want a unit that has accurate and quick readings, then look for a unit with a higher wattage. Low wattage devices are slower and work better in shallow water.
This occurs because the fish finder converts the sonar waves created by the transducer. With lower watts, the readings aren’t accurate, and the sonar waves are slower. When the device has more power, it provides accurate readings and delivers faster waves.
Note:
- For 100 watts of power at 50 kHz, the fish finder will show readings of 400 ft.
- For 100 watts of power at 50 kHz, the fish finder will show readings of 100 ft.
Most fish finders in the mid-range use dual-range frequencies. That way, you can view the frequencies from a split-screen mode.
Transducers
Transducers are an important part of every fish finder. They transmit and receive sonar waves. Once the waves are emitted in the water, they bounce off objects and show their location. After this, the waves are picked up by the transducer.
Once the data comes back, it will be sent to the transducer unit. Then the signal is processed and creates a picture that’s easy to read and understand.
Transducers have different mounts for different occasions. If you want one that’s simple to install, consider getting a transom mount. But if you want something more advanced or have a larger boat, then you can go for a thru-hull mount.
Transducer Material
Depending on the boat you’re operating, you’ll have to find the right transducer material. For casual fishing purposes, a plastic transom mount will work. They are compatible with virtually any boat and kayak.
If you have an in-hull or thru-hull mount, metal or fiberglass hulls will need plastic housing. Steel or aluminum hulls will need stainless steel housing. Bronze housings are required for wooden hulls.
Frequently Asked Questions
Can I Change the Batteries Myself?
The answer depends on what batteries are compatible with your fishfinder. For instance, if your fish finder uses AAA batteries, then you’ll have to replace them when they run out. However, if they have lithium batteries than you can recharge them once the power is low, check the battery type of your fishfinder to ensure it gets the battery power, it needs to operate smoothly.
How Deep In The Water Can You Fish?
Look at the depth range of your fish finder before buying. If you’re fishing for a hobby, then a fish finder with a depth range of 100-140 is good for you. For serious anglers, there are fish finders that have a depth range of 150-320 feet.
Does the fishfinder work with Amazon Kindle?
Check the compatibility of your device. Most fishfinders work with iOS and Android systems. Since mobile software is changing, check which version of your phone system it supports. This will ensure that you get the right fishfinder for your fishing needs.

For serious shore anglers looking to up their game, the Deeper PRO+ is a great choice. It’s built-in GPS can be used to create bathymetric maps, which can be used to mark frequent fishing spots, retrieve, save, and even analyze all of your maps and scans.

Coverage is necessary when fishing outdoors, and the Humminbird 41060 has a lot of it. With over 320 feet of depth detection, you won’t miss a fish floating around underwater. In fact, you’ll get better sonar coverage with its 28°, 16°, & 74° at -10 dB.
The Humminbird tends not to work unless fishing under 15 feet. And the device will go from 20 to 6 feet on its reading, which makes it difficult to get an accurate description of the fish underwater. Because of its inaccurate readings, its a clear reason why it’s not in the top 5 on this list.
