Overview / What Is Lewmar AA570 Chain Counter

The Lewmar AA570 Chain Counter for Boats & Marine Engines is an advanced digital display system that accurately measures and displays the length of anchor rode deployed. Designed to work with various Lewmar windlasses, it integrates seamlessly into your vessel’s electrical system, providing a live reading as the chain moves in or out of the windlass.

One of the standout features of the AA570 is its compatibility with both rope and chain configurations, making it a versatile option for many boat setups. The screen provides crisp, easy-to-read feedback and allows users to control the windlass remotely, depending on system configuration. This accessory isn’t just about convenience—it’s about improving anchoring safety by eliminating guesswork, especially in deep water or poor visibility conditions.

Why Boaters Choose the Lewmar AA570 Chain Counter

Choosing a high-quality chain counter like the AA570 is essential for any serious boater. Here are some of the reasons it stands out:

• Precision Deployment: Know exactly how much chain you’ve released.
• Wireless Interface: Optional remote-control compatibility adds flexibility.
• Customizable Settings: Adjust length units and anchor speed.
• Durable Build: Water-resistant casing and marine-grade construction.

Many customers report improved anchor holding performance simply because they can consistently deploy the right amount of chain—especially critical when anchoring in tidal or current-heavy areas.

How to Install Lewmar AA570 Chain Counter

Installing the Lewmar AA570 Chain Counter for Boats & Marine Engines is a straightforward process but may require basic knowledge of marine electrical systems. Follow these general steps:

1. Disconnect the battery power and ensure the windlass circuit is off.
2. Mount the AA570 display in a visible location near the helm or anchor station.
3. Connect the sensor to the gypsy or windlass shaft, ensuring accurate revolution readings.
4. Run the cabling from the sensor to the AA570 unit, securing it along the way.
5. Reconnect power and calibrate the unit based on your chain length and windlass model.

Once calibrated, the display will begin reading the chain’s length automatically as you raise or lower your anchor. Calibration should always be double-checked during first use for accuracy.

Lewmar AA570 Chain Counter Maintenance Tips

Regular maintenance will ensure your chain counter continues functioning for years. Here are some essential tips:

• Sensor Cleaning: Inspect the sensor for rust, corrosion, or grime every few months. Clean with a marine-safe cleaner.
• Cable Check: Ensure all cables are firmly attached and not showing signs of saltwater exposure.
• Screen Protection: Use a screen cover or hood to protect the display from UV damage when not in use.
• Annual Calibration: Recalibrate yearly or after making changes to your anchor chain or rode.

With just a few preventive steps, the Lewmar AA570 Chain Counter will remain accurate and functional through every season.

Benefits of Digital Chain Counting for Anchoring

Incorporating a chain counter isn’t just a matter of tech—it’s about improving boating safety and simplifying your anchoring routine. Traditional anchoring depends heavily on visual cues or counting chain links, which can be inaccurate. The AA570 eliminates this guesswork and offers:

• Peace of Mind: Know your anchor is deployed at the right depth.
• Enhanced Efficiency: Quick and confident deployment every time.
• Data Accuracy: Get consistent readings in all weather conditions.

These advantages lead to better holding performance and less time repositioning or adjusting your anchor set.

• Blank Display: Check power connections, fuse, and battery voltage.
• Inaccurate Readings: Recalibrate the system using the user manual.
• Sensor Not Detected: Verify that the sensor is correctly mounted and the cable isn’t damaged.
• Unit Freezing: Disconnect power, wait 60 seconds, and restart the unit.

Always consult the user manual for detailed error codes and contact Lewmar support for persistent issues.

Detailed FAQ Section

How do I calibrate the Lewmar AA570 Chain Counter?

Calibrating the Lewmar AA570 Chain Counter involves programming the unit to recognize how much chain has been deployed per revolution of the windlass. Start by ensuring the windlass and chain sensor are installed correctly. Then, access the settings menu on the AA570 interface. Enter the chain length per rotation and total chain length. Deploy and retrieve a test length, usually 10 meters, and ensure the reading is accurate. If not, recalibrate. It’s recommended to perform this process in calm water. Calibration ensures safety and accuracy, especially when anchoring in deep water or under challenging conditions.

Is the Lewmar AA570 waterproof?

Yes, the Lewmar AA570 Chain Counter is built to marine-grade standards and offers excellent resistance against water ingress. The display unit is sealed and rated to handle typical spray, light rain, and humidity levels found in marine environments. However, it is not designed to be submerged. For long-term protection, especially in open cockpits, it’s a good idea to use a protective hood or mounting cover. Routine inspections and cleaning of the unit will help maintain its resistance against saltwater corrosion and UV degradation, ensuring years of dependable service.

What type of sensor does the Lewmar AA570 use?

The Lewmar AA570 Chain Counter typically utilizes a magnetic or optical sensor that detects rotations of the windlass gypsy or chain wheel. This sensor reads chain movement with high precision and sends data to the display unit. Depending on your windlass model, the sensor may come included or need to be purchased separately. Always verify compatibility with your windlass before purchasing. Sensor performance is key to accurate measurements, and proper alignment during installation is critical. Lewmar’s manual includes clear guidance for sensor setup, wiring, and calibration.

Can I use this chain counter with other windlass brands?

While the AA570 is designed specifically for Lewmar windlasses, it may be compatible with other brands depending on sensor types and output signals. However, Lewmar does not officially guarantee performance or support for non-Lewmar units. If you plan to use the AA570 with a different windlass, consult both the AA570 manual and your windlass documentation. Often, third-party installations require custom sensor brackets or wiring adjustments. In general, pairing with Lewmar windlasses ensures seamless functionality and avoids technical issues.

How much does the Lewmar AA570 Chain Counter cost and is it worth it?

The Lewmar AA570 Chain Counter typically ranges between $300–$450, depending on vendor, shipping, and whether the sensor is included. While the price may seem high, it’s a valuable investment for safety, peace of mind, and anchoring efficiency. Especially in deeper waters or unfamiliar anchorages, knowing your chain length can prevent anchor drag and protect your vessel. Compared to manually counting links or estimating chain by feel, the AA570 is a smart, long-lasting solution for serious boaters.
