Your Finish, Your Choice.\u003c\/h2\u003e\u003cp\u003eThe Humminbird HDR 650 is a high-performance in-dash digital depth gauge built for boaters who push the throttle. It reads bottom depth accurately to 600 feet at speeds up to 70 mph — well beyond what most gauge-style sounders can handle — making it a strong choice for fast powerboats, ski boats, and performance runabouts where a chartplotter-style unit isn't the right fit.\u003c\/p\u003e\u003cp\u003eThe 1-1\/4\" backlit LCD display is large and easy to read, with shallow and deep water alarms that alert you before you reach a depth you've flagged. Readings are available in feet, fathoms, or meters.\u003c\/p\u003e\u003cp\u003eOne standout feature: the HDR 650 ships with two face plates (white and black) and three trim rings (black, white, and silver), so you can match your helm panel without ordering a separate bezel kit. It mounts in a standard 2-1\/8\" gauge hole and is fully waterproof.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDepth Range: 600 ft\u003c\/li\u003e\n\u003cli\u003eMaximum Speed: 70 mph\u003c\/li\u003e\n\u003cli\u003eDisplay: 1-1\/4\" backlit LCD\u003c\/li\u003e\n\u003cli\u003eAlarms: Shallow and deep water\u003c\/li\u003e\n\u003cli\u003eUnits: Feet, fathoms, or meters (switchable)\u003c\/li\u003e\n\u003cli\u003eGauge Hole Size: 2-1\/8\" standard\u003c\/li\u003e\n\u003cli\u003eWaterproof: Yes\u003c\/li\u003e\n\u003cli\u003eIncludes: Transom-mount transducer, 2 face plates (white \u0026amp; black), 3 trim rings (black, white \u0026amp; silver)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIn the Box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHDR 650 depth gauge display\u003c\/li\u003e\n\u003cli\u003eTransom-mount transducer\u003c\/li\u003e\n\u003cli\u003e2 face plates (white and black)\u003c\/li\u003e\n\u003cli\u003e3 trim rings (black, white, and silver)\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e The HDR 650 is the right pick for fast boats — particularly performance runabouts, ski boats, and bass boats — where speed-rated depth accuracy matters and a traditional gauge-hole mount is preferred over a chartplotter. The 70 mph speed rating sets it apart from most in-dash depth gauges, which typically top out at 35–45 mph. If your boat runs fast and you want a clean helm-mounted depth readout rather than a multifunction display, this is the unit to spec.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGauge hole note:\u003c\/strong\u003e This unit requires a 2-1\/8\" hole, which is slightly larger than the 2-1\/16\" standard used by most Faria and Garmin gauge-style sounders. Confirm your panel cutout before ordering.
