Marine Compasses, Gauges & NMEA Networking Equipment

Beyond the chartplotter, a boat still needs the basics done right: knowing your heading, keeping an eye on engine vitals, and getting all your electronics talking to each other. CritPro carries marine instruments, compasses, and networking gear built for real use at the helm, as part of our full boating selection for boat owners who want a helm that actually works together.

What to Look for in Instruments, Compasses & Networking Gear

A magnetic compass is not just a backup for electronics, it is the one instrument on the boat that works with no power at all. Choose a compass sized and dampened for your boat's typical ride, since a compass built for calm inland water will swing too much on a boat that pounds through chop offshore. Mount it where you can actually see it from your normal seated position at the helm, not just where it fits.

Gauges and senders need to match your engine and fuel system, not just look right on the dash. Mismatched senders are one of the more common reasons a fuel or temperature gauge reads wrong from day one. For networking, NMEA 2000 is the standard that lets your gauges, sensors, and displays share data over one backbone instead of a tangle of separate wiring, and it is worth building any new install around it from the start rather than adding it piecemeal later.

What This Category Covers

Instruments, compasses, and networking gear at CritPro includes magnetic compasses, analog and digital gauges, senders and sensors, NMEA 2000 networking components, gateways, and cabling. Whether you are outfitting a new helm or tying an existing system together, this category covers what keeps you informed and your electronics talking to each other.

Pairing Instruments & Networking with Other Boating Equipment

Instruments and networking gear tie directly into the rest of your marine electronics, and a properly networked helm lets your fish finder, chartplotter, and gauges all share the same data instead of running as separate islands. Our full boating selection covers everything else needed to outfit the helm.
