DC Digital Ammeter with ±500A Range — Shunt Included
The Blue Sea Systems 8236 DC Digital Ammeter gives you a clear, real-time readout of current flow in your DC electrical system. Large LED digits are easy to read at a glance, with three selectable brightness levels so the display stays comfortable in both bright sunlight and low-light conditions. The splash-proof housing is built for the marine environment, and the compact face fits a standard 2" round mounting hole — making it a straightforward drop-in for most helm panels.
The ±500A measurement range covers both charge and discharge current in a single display, so you can monitor battery banks, alternators, and loads without switching between instruments. A 500A shunt is included in the box.

Parts Desk Insights
Best suited for boaters who want a dedicated, easy-to-read current monitor at the helm without adding a full multi-function display. The ±500A bidirectional range makes it particularly useful on vessels with larger battery banks where tracking both charging input and load draw matters. If you need voltage monitoring alongside current, pair this with the Blue Sea Systems 8003 DC Analog Voltmeter or the Blue Sea Systems 8015 DC Analog Voltmeter Panel for a complete helm monitoring setup. Confirm your panel cutout is a true 2" round hole before ordering — the face is slightly larger at 2.625" wide but the mounting hole requirement is 2".
