Top 3 Castable Fish Finders For Shore Fishing On Fishing Kayak

Fishing from shore or a fishing kayak can be tricky. You can’t always see what’s happening under the water. This is where castable fish finders come in handy. These small devices can be thrown into the water to show you what’s going on below the surface.

Castable fish finders have changed the game for many anglers. They help you find fish, understand the underwater landscape, and even check water temperature. This means you can make smarter choices about where to cast your line.

In recent years, these devices have become more popular and more advanced. They’re now smaller, easier to use, and packed with helpful features. Many can connect to your smartphone, giving you a clear view of the underwater world right in the palm of your hand.

For shore fishing and fishing kayak enthusiasts, castable fish finders are a great tool. They’re portable, easy to use, and can greatly improve your chances of catching fish. Let’s look at some of the best options available today.

Garmin STRIKER Cast

The Garmin STRIKER Cast is a compact castable fish finder that packs a punch for its size. We tested this device in various conditions, from shore fishing to kayak angling, to see how it performs.

This small blue plastic ball weighs just 75 grams, making it easy to cast and retrieve. It connects to your smartphone via Bluetooth, displaying sonar readings through the Garmin STRIKER Cast app.

The STRIKER Cast offers two sonar frequencies: 260 kHz for a wider scan and 455 kHz for more detailed views. We found the 260 kHz setting useful for quickly locating fish and structure, while the 455 kHz mode provided clearer images of underwater objects.

During our tests, the device showed accurate depth readings up to about 150 feet. The water temperature feature was also spot-on, helping us understand fish behavior better.

One standout feature is the GPS-enabled mapping. The STRIKER Cast can create custom Quickdraw Contour maps with 1-foot contours. This proved invaluable for finding and remembering productive fishing spots, especially in unmapped waters.

The device’s battery life impressed us. We used it for over 6 hours without needing a recharge. However, we noticed our phone’s battery drained faster while using the app, especially in colder weather.

For fishing kayak users, the STRIKER Cast works well when towed behind at slow speeds. We did experience occasional disconnects when moving too quickly, but this wasn’t a major issue.

The app interface is user-friendly, with options to switch between traditional 2D sonar and an ice fishing flasher mode. We appreciated the ability to adjust settings like gain and range directly from our phones.

ProsCons
Portable and lightweightBluetooth range limited to about 60 meters
Accurate depth and temperature readingsOccasional disconnects at higher speeds
GPS mapping capabilityPhone battery drain

During our trials, we found the Deeper Pro easy to use from shore or a fishing kayak. Its lightweight design allows for effortless casting, enabling quick scans of different areas. The sonar proved reliable in detecting fish, mapping bottom structure, and providing depth readings up to about 260 feet.

The app interface is intuitive, offering options to adjust sensitivity and view modes. We particularly appreciated the split-screen feature that displays both 2D sonar and a flasher-style view simultaneously. The GPS-enabled mapping function stood out as especially useful, allowing us to create custom contour maps of unmapped waters.

Battery performance was impressive, lasting through several extended fishing sessions. However, we noticed increased drain on our phone’s battery while using the app, particularly in colder conditions.

For fishing kayak users, the Deeper Pro performed adequately when towed at slow speeds. We experienced occasional signal drops in choppy water or when moving too quickly, though this is typical for most castable units.

ProsCons
Highly portable and easy to castSignal interruptions in rough water
Accurate fish and structure detectionSmartphone battery drain with extended use
GPS mapping capabilityLimited advanced sonar features
Impressive battery lifeNo built-in display
Versatile for shore and kayak useWi-Fi range limited to about 330 feet

The Deeper Pro Fish Finder is well-suited for shore anglers, kayak fishers, and those exploring small or unmapped bodies of water. Its portability and mapping features make it a valuable tool for discovering new fishing spots.

While it may not replace a full-sized fish finder for serious boat anglers, the Deeper Pro offers a good balance of features for its price point. It’s particularly effective for quickly scanning different areas from shore or a fishing kayak, helping anglers make more informed decisions about where to focus their efforts.

During our tests, we found its Bluetooth connectivity to be reliable, offering a stable connection to our smartphone within its 100-foot range.This fish finder’s spherical design, resembling a traditional bobber, allows for smooth casting and retrieval. We appreciated its 10-hour battery life, which lasted through our entire day of fishing without needing a recharge.The iBobber’s sonar technology provides decent underwater readings, though not as detailed as some higher-end models. It effectively showed us fish locations, water depth, and temperature. The fish alarm feature was particularly useful, alerting us to potential catches without constant screen monitoring.We found the accompanying app user-friendly, offering features like waterbed mapping, trip logs, and GPS tracking. These additions enhanced our overall fishing experience, helping us mark productive spots for future visits.While the iBobber’s 100-foot range is shorter than some competitors, we found it sufficient for most shore fishing scenarios from our fishing kayak.

Why Use A Castable Fish Finder For Shore Fishing

Castable fish finders have revolutionized shore fishing, offering anglers unprecedented insights into underwater environments. These compact devices provide several key advantages:

Improved Fish Location: Castable fish finders allow shore anglers to scan large areas quickly, identifying fish-holding structures and depth changes that are invisible from the surface. This capability significantly increases the chances of locating fish.

Depth Mapping: Many castable fish finders offer GPS mapping features, enabling anglers to create detailed contour maps of fishing spots. This information is invaluable for understanding underwater topography and finding productive areas.

Portability: Unlike traditional boat-mounted fish finders, castable units are highly portable. They can be easily carried in a tackle box or backpack, making them ideal for shore fishing or use from small watercraft like fishing kayaks.

Cost-Effective: Castable fish finders often provide advanced features at a lower cost compared to full-sized units, making them an attractive option for anglers on a budget.

Versatility: These devices can be used for various fishing scenarios, from shore casting to ice fishing, offering year-round utility.

Tips For Using Castable Fish Finders From Shore Or Fishing Kayak

To maximize the effectiveness of your castable fish finder:

  1. Practice Casting: Use a heavier rod and line to cast the device accurately and prevent losing it.
  2. Scan Systematically: When shore fishing, cast in a fan pattern to cover a wide area efficiently.
  3. Interpret Data Carefully: Remember that fish icons on the display are interpretations of sonar returns, not guaranteed fish sightings.
  4. Use in Conjunction with Other Methods: Combine the fish finder’s data with your knowledge of fish behavior and seasonal patterns for best results.
  5. Protect Your Smart Device: Use a waterproof case or float for your phone or tablet when fishing.
  6. Maintain Battery Life: Turn off the unit when not in use and carry a portable charger for extended trips.
  7. For Kayak Use: When using from a fishing kayak, troll the device slowly behind you for a continuous read of the water column.
  8. Update Software: Regularly check for and install app updates to ensure you have the latest features and improvements.

By following these guidelines and choosing the right castable fish finder for your needs, you can significantly enhance your shore fishing and fishing kayak experiences, increasing your chances of locating and catching fish in various water bodies.
