Wireless Fish Finder - Rechargeable Sonar Sensor 45M Depth for Portable Fishing

Rechargeable Wireless Fish Finder - 45M Depth Sonar Sensor with 2.4" Color Display

Locate fish with precision and confidence using this advanced wireless fish finder featuring rechargeable battery, 45-meter depth capability, and real-time sonar imaging. The portable design with 2.4-inch color LCD display delivers critical underwater data—fish position, water depth, temperature, and bottom contour—helping you find productive fishing spots faster and catch more fish. Perfect for serious anglers who demand professional-grade fish-finding technology in a portable, user-friendly package.

Wireless Sonar Technology - 150M Range

The wireless sonar sensor transmits underwater data up to 150 meters (492 feet) to your handheld display, giving you the freedom to fish from shore, dock, kayak, or boat without cable limitations. Cast the sensor into your fishing zone and receive instant feedback about what's below the surface. The wireless design eliminates tangled cables and allows you to cover more water efficiently.

45-Meter Depth Capability

Scan depths up to 45 meters (147 feet) to locate fish holding in deep water, identify structure and drop-offs, map bottom contours for productive zones, and find thermoclines where fish concentrate. The substantial depth range handles most freshwater and inshore saltwater fishing scenarios, from shallow flats to deep reservoir channels.

2.4-Inch TFT Color LCD Display

The bright, easy-to-read color screen displays detailed sonar returns in real-time, making it simple to distinguish fish from structure, vegetation, and bottom composition. The color differentiation helps you interpret underwater conditions quickly, even in bright sunlight. The compact 2.4-inch screen balances portability with readability.

90-Degree Beam Angle Coverage

The wide 90-degree sonar beam at 125 kHz provides extensive underwater coverage, scanning a large area beneath and around the sensor. The broad beam angle increases your chances of locating fish and structure, making it ideal for searching new water and identifying productive fishing zones quickly.

Comprehensive Underwater Data

Continuously monitor critical fishing information including water depth for safe navigation and structure identification, water temperature to find optimal fish zones, fish position and depth for precise presentation, bottom contour to locate drop-offs and structure, and fish size indicators to target trophy fish. All the data you need to make informed fishing decisions appears on one screen.

Rechargeable Lithium Battery

The built-in 3.7V lithium battery eliminates the need for disposable batteries, saving money and reducing environmental impact. Charge via the included USB cable using the wall adapter, car charger, or any USB power source. The rechargeable design ensures you're always ready to fish without worrying about battery availability.

Multiple Charging Options

Charge your fish finder using the included wall charging head for home charging, car charging head for vehicle charging between fishing spots, or USB data cable for power bank or laptop charging. The versatile charging options mean you can recharge anywhere, keeping your fish finder powered during extended fishing trips.

Customizable Settings

Tailor the fish finder to your preferences and fishing conditions with user-selectable zoom for detailed viewing, sensitivity adjustment for different water conditions, depth units (feet or meters), depth range customization, shallow water alert for safety, fish icon display on/off, fish alert notifications, and chart speed settings. Save your preferred settings in built-in memory—they're retained even when the unit is powered off.

Portable and Lightweight Design

The compact, handheld design fits easily in tackle boxes, fishing vests, or backpacks. Take it anywhere you fish without the bulk and weight of traditional boat-mounted fish finders. The portable format makes it perfect for anglers who fish from multiple locations or prefer mobility over permanent installations.

Splash-Proof Construction

The Level 4 waterproof rating protects against splashes, rain, and wet conditions common in fishing environments. While not submersible, the splash-proof design handles the moisture exposure typical of fishing activities, ensuring reliable operation in real-world conditions.

Fish Alert and Shallow Water Warning

Enable fish alert to receive notifications when fish are detected, allowing you to focus on fishing rather than constantly watching the screen. The shallow water alert warns you of depth changes that could pose navigation hazards, adding a safety dimension to your fishing electronics.

Bottom Contour Mapping

Understanding bottom structure is critical for locating fish. The continuous bottom contour display reveals drop-offs where predators ambush prey, humps and points that concentrate fish, channels and ledges that provide migration routes, and hard bottom versus soft bottom composition. Use this structural information to position your bait in high-percentage zones.

Temperature Monitoring

Water temperature directly affects fish behavior and location. Monitor temperature to find optimal zones for target species, identify thermoclines in stratified water, track seasonal temperature changes, and predict fish activity levels. Temperature data transforms guesswork into strategic fishing.

Wide Operating Temperature Range

Function reliably in conditions from 14°F to 122°F (-10°C to 50°C), covering everything from ice fishing to summer heat. The broad operating range ensures year-round performance regardless of weather conditions.

Complete Package Includes

• Main display unit with rechargeable battery

Easy to Use

No complicated installation or technical expertise required. Charge the unit, power it on, cast the wireless sensor into the water, and start receiving sonar data immediately. The intuitive interface and straightforward controls make it accessible for anglers of all experience levels.

Pre-Use Charging Recommendation

For optimal performance, fully charge the device before first use. This ensures maximum battery life and allows you to spend more time on the water without interruption.

Find More Fish

Stop wasting time fishing unproductive water. This wireless fish finder shows you exactly where fish are holding, what depth they're at, and what the bottom structure looks like. Use this information to position your bait precisely in the strike zone, dramatically increasing your catch rate and fishing success.
