Imagine dropping anchor in a crowded bay without the guesswork—knowing exactly how much rode you've deployed, with one-touch precision and built-in safeguards. The Lewmar AA570 chain counter transforms chaotic anchoring into a seamless process, whether you're handling all-chain setups or mixed rope and chain rodes. This wireless panel-mount solution connects effortlessly to your windlass, delivering real-time feedback right where you need it most: at the helm.
Boaters rave about its docking alarm that signals when you're nearing the end of your rode, preventing overruns that could tangle your propeller or damage gear. Pair it with multiple stations for helmsman and crew coordination, making it ideal for larger vessels exploring remote coves or busy marinas.
These features aren't just bells and whistles—they're proven to reduce anchoring stress, especially in low visibility or strong currents where every meter counts.
The magic happens via a grey sensor that mounts near your windlass gypsy, detecting chain links or rope passages with a simple magnet. Paired with the base station and console, it tracks deployment down to the meter, displaying it on an intuitive panel. Motor load sensors fine-tune accuracy for hybrid rodes, ensuring you never deploy too much or too little.
In practice, sailors use it to preset 5:1 scope for holding power, then retrieve precisely to avoid chain pile-ups on deck. The wireless link means you can monitor from anywhere on board, perfect for single-handing or coordinating with deck crew via VHF.

Engineered for harsh saltwater environments, it shrugs off spray, UV exposure, and temperature swings, ensuring years of reliable service.
Everything arrives ready to install, minimizing downtime and tools needed.
Mount the sensor close to the chain wheel without contact—aim for a 2-3mm gap with the magnet. Route cables away from high-vibration areas, and test the wireless link in open water before your first outing. For multi-station setups, sync units during initial power-up. Most installs take under an hour for experienced hands, blending right into factory windlass wiring.
Common pitfall to avoid: Over-tightening sensor mounts, which can skew readings. Calibrate your rode length post-install by deploying a known amount and adjusting via the console menu.
It handles both all-chain and rope/chain combinations using the included grey sensor and motor load terminators for spot-on accuracy across setups.
Yes, it's fully compatible with DC, AC, and hydraulic windlasses, monitoring rode without interfering with motor operation.
The panel-mount console communicates wirelessly with the base station at the windlass, offering cable-free installation and reliable range throughout most vessels.
Absolutely—install up to two standalone or combine with other Lewmar series like AA150 or AA710 for multi-station monitoring.
It provides audible and visual warnings as you approach pre-set rode limits, preventing chain overruns that could foul your propeller or deck.
Exceptionally precise, tracking to the meter via sensor and magnet detection, with calibration options for your specific rode calibration.
Rated from -5°C to 60°C, it's tough enough for tropical heat or chilly northern latitudes, with IP-rated protection against spray.
