How long can the sonar work on a single charge?

The sonar provides up to 4 hours of continuous use on a full charge, depending on operating conditions and settings.

Is this sonar suitable for shallow water?

Absolutely. This sonar is specifically optimized for shallow water environments . It can detect fine targets as small as 10 mm , delivering clearer detail where structure and fish are often tightly packed.

Can I review sonar data after scanning?

Yes. The app allows you to rewind and review previous sonar data , so important details are never lost. This is especially useful for analyzing structure and confirming potential spots after scanning.

Does the sonar turn on and off automatically?

Yes. The sonar automatically powers on when placed in water and turns off after being out of water for 5 minutes. This helps conserve battery life and ensures a simple, hands-free user experience.

Can I adjust the sonar sensitivity?

Yes. Sensitivity can be adjusted directly in the app, allowing you to either filter out noise for a cleaner display or retain more raw data for detailed interpretation.

Is the sonar stable during retrieval?

Yes. The sonar features multiple screw mounting points , allowing you to select the optimal position based on your height above the water. This helps keep the sonar vertical during retrieval, ensuring more stable and accurate scanning.

Does it work without mobile data?

Yes. Sonar data works without mobile data. Mobile data is only required if you wish to use online or satellite maps . Offline maps can be downloaded in advance.

Perfect for every fishing style

Use it from the shore, on the ice, in a kayak, or from a float tube.
The BEETACKLE sonar gives you clear depth and fish readings wherever you fish. Compact, wireless, and easy to use — helping you find fish faster in any condition.

Shore Fishing: Cast the sonar out from the bank to quickly check depth, bottom contours, and fish presence.

Ice Fishing: See what’s happening below the ice in real time.

Kayak Fishing: Mount the sonar from your kayak to see depth, structure, and fish beneath you in real time.

Float Tube: Mount the sonar directly to your float tube for real-time depth, structure, and fish readings beneath you.

0.3m Shallow Water Precision

Most fish finders lose accuracy in water under 1 meter.

BEETACKLE is specially optimised for shallow water, detecting fish and structure from just 0.3m.

Perfect for margins, weed beds, and shallow feeding areas — so you never miss what others can’t see.

True 100m

Many castable sonars claim a 100-meter range, but in real fishing conditions, that number often proves unreliable.

Our sonar is engineered to deliver a true, usable communication distance of up to 100 meters, not a lab-tested figure.

- Stronger signal penetration over water

- Significantly improved stability at long distances

- Reliable real-time data transmission, even at extreme casting range

High Precision – 10 mm Target Detection

BEETACKLE castable sonar can detect targets as small as 10 mm, delivering clear and highly detailed imagery.The advanced tri-beam design ensures both resolution and coverage:

- 680 kHz / 7° – ultra-fine detail for close inspection

- 230 kHz / 20° – balanced coverage for everyday scanning

- 100 kHz / 47° – wider beam for deeper detection

Wireless Charging -Fully Sealed -Effortlessly Reliable

Traditional castable sonars rely on exposed charging ports or Type-C connectors that must be unscrewed before charging.

Every opening introduces risk — water ingress, worn seals, and long-term reliability issues.

Our sonar eliminates this weakness entirely.

Simply place the sonar on the charging base and let it charge safely and effortlessly.

- Full charge in approximately 2.5 hours

- LED indicator stays solid when charging is complete

- Designed for long-term use in wet, demanding environments

Turn Raw Data Into Clear 2D & 3D Maps

Understanding structure, contours, and subtle changes in terrain is what truly reveals productive fishing spots.

Using the app, our sonar allows you to create detailed 2D and 3D depth maps automatically as you scan the water.

This enables you to:

- Visualize underwater terrain clearly

- Identify drops, humps, channels, and transitions

- Mark and revisit promising spots with confidence

Instead of guessing based on isolated readings, you gain a clear, intuitive view of the riverbed, helping you make smarter decisions and fish more effectively.
