Lewmar Chain Counter AA570 – Durable & Smart Tool
Lewmar AA570 Chain Counter for Boats & Marine Engines
Introduction
Managing your anchor chain with precision is crucial for boat safety and operational efficiency. The Lewmar Chain Counter AA570 provides boaters with real-time chain length readouts, ensuring safe and accurate anchoring every time. Specifically designed for seamless integration with Lewmar windlasses, the AA570 elevates anchoring to a new level of reliability and control.
This essential marine accessory features a clear LCD screen, waterproof construction, and intuitive controls that even novice boaters can handle confidently. Whether you’re docking, anchoring overnight, or maneuvering in tricky coastal zones, the Lewmar Chain Counter ensures you always know your chain status down to the foot.
Overview / What Is Lewmar Chain Counter AA570
The Lewmar Chain Counter AA570 is an advanced digital device that accurately measures and displays the deployed length of anchor chain. Installed at the helm or cockpit, it connects to your windlass system and gives real-time data as you anchor or retrieve the chain. This improves both safety and efficiency on board, especially in unfamiliar or deep anchorages.
More than just a counter, the AA570 integrates seamlessly with Lewmar windlasses and comes with an auto-stop feature that can prevent accidental overwinding, thereby protecting your windlass motor and chain. Its waterproof rating and high-contrast display make it suitable for harsh marine conditions and night-time operations.
Top Benefits of Using Lewmar Chain Counter
The Lewmar Chain Counter AA570 is more than a convenience — it’s a crucial upgrade for any boat with a powered anchor system. Below are the standout advantages:
- Precision Anchoring: Know exactly how much chain is deployed to ensure optimal scope and safety.
- Improved Motor Life: Auto-stop prevents overwinding, extending the life of your windlass motor.
- Increased Safety: Reduce human error and eliminate guesswork in anchoring.
- Easy Integration: Plug-and-play design compatible with all major Lewmar windlasses.
- Backlit LCD Display: Read the counter even in low-light or night conditions.
These features make the Lewmar Chain Counter a valuable addition for boaters looking for both safety and convenience in their anchoring systems.
How to Install Lewmar Chain Counter Properly
Installing the Lewmar Chain Counter AA570 is straightforward but requires careful attention to wiring and windlass compatibility. Here’s a step-by-step overview:
- Mount the display unit at the helm using the included bracket or surface mount template.
- Connect the unit to the windlass sensor cable and power source, ensuring proper polarity.
- Use waterproof connectors and route cables through safe, dry paths to prevent corrosion.
- Calibrate the chain length using the Lewmar guide; this ensures accuracy in readings.
For best results, refer to the official Lewmar installation manual or hire a marine electrician. A well-installed counter will function reliably for years, even in challenging weather.
Maintenance Tips
To ensure your Lewmar Chain Counter operates flawlessly, regular maintenance is key. Follow these expert-backed tips:
- Monthly Inspection: Check for any cable wear, water intrusion, or corrosion near connections.
- Screen Cleaning: Wipe the LCD with a soft, damp microfiber cloth to remove salt residue.
- Firmware Check: Occasionally update the unit if firmware updates are available from Lewmar.
- Sensor Alignment: Make sure the windlass sensor is properly aligned and free of chain debris or obstructions.
With proper care, the Lewmar Chain Counter can last over 5 years without issue. This maintenance is minimal but crucial for long-term success.
Lewmar Chain Counter Troubleshooting Guide
If your Lewmar Chain Counter AA570 malfunctions, don’t worry — many issues are user-correctable. Here are common problems and solutions:
- Display Not Powering On: Check for blown fuses or loose connections in the power line.
- Incorrect Chain Count: Recalibrate the unit and ensure the chain counter sensor is clean and in the correct position.
- Screen Flickering: Verify voltage stability; a battery monitor may be helpful to detect irregular power input.
If problems persist, consult Lewmar’s support or a marine electronics technician. Many users report that most issues can be resolved with simple recalibration or re-securing loose cables.
Lewmar Chain Counter vs Manual Chain Marking
While some boaters use manual paint or plastic markers on their chain, this method has serious drawbacks. Markings fade, wash off, or get obstructed by mud and grime, making them unreliable. On the other hand, the Lewmar Chain Counter AA570 provides digital precision that doesn’t degrade over time or depend on visibility.
Manual methods also require crew at the bow to watch and count links during operation, increasing the chance of human error. A chain counter streamlines anchoring, requiring less manpower and providing better outcomes every time.
Expert Advice and Pro Recommendations
Seasoned captains and marine techs often recommend upgrading to a chain counter early in your boat ownership. It reduces operational stress, increases anchoring success rate, and minimizes wear on critical gear.

Detailed FAQ Section
How do I calibrate the Lewmar Chain Counter for accurate readings?
Calibration involves setting the length per chain mark and ensuring the sensor is aligned. First, deploy a known length of chain (e.g., 10 feet), then access the setup menu on the AA570. Input the chain length and let the counter learn how many pulses equal that distance. Once complete, test accuracy by fully deploying and retrieving the chain. Calibration ensures error-free tracking and allows for auto-stop configuration.
Can I use the Lewmar Chain Counter AA570 with non-Lewmar windlasses?
While the AA570 is designed for Lewmar windlasses, it can be used with other models if compatible sensors and electrical interfaces are present. However, auto-stop functionality may be limited or disabled depending on how the external windlass behaves. Consult your boat technician or refer to Lewmar’s compatibility chart for specifics before installation.
How weatherproof is the Lewmar Chain Counter AA570?
The unit is rated IP67, meaning it is fully protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. This makes it suitable for outdoor helm installations. However, protection from direct hose spray and regular inspection of seals and cable entries is advised to maintain integrity over time. Many boaters install it in partially sheltered cockpits for maximum life expectancy.
What kind of power supply is required to run the AA570 Chain Counter?
The Lewmar Chain Counter requires a 12V DC power supply, standard on most boats. It draws minimal current, ensuring your battery remains unaffected during extended use. Power cables should be marine-grade and fused to prevent overload. Always use proper cable management and secure wiring to reduce shock and vibration stress.
Is the Lewmar Chain Counter easy to use for first-time boaters?
Yes. The AA570 is designed with an intuitive interface, using large buttons and a clear backlit display. It comes pre-configured for plug-and-play operation, and the instruction manual walks new users through every step. In less than 10 minutes, most users are fully comfortable reading and interpreting the counter, making it a must-have for both new and experienced boaters.
Conclusion
The Lewmar Chain Counter AA570 is an essential tool that improves accuracy, safety, and convenience in anchoring operations. Whether you’re boating recreationally or managing a serious marine vessel, this accessory enhances your confidence and control at the helm. With easy installation, rugged design, and smart features like auto-stop and calibration, the AA570 is worth every penny for peace of mind.
