Description
The Garmin B619 is a 500 W bronze thru-hull transducer that works at two fixed frequencies, 77 kHz and 200 kHz, providing depth and water temperature to 900 ft. The 77 kHz frequency gives a wide 45 degree beam for broad coverage and good performance in deeper water, while the 200 kHz frequency narrows to a 15 degree beam for sharp, detailed returns in the shallows. Unlike broadband CHIRP transducers, the B619 runs at these set frequencies.
The tilted-element bronze housing sits near-flush in the hull, with only about 5 mm protruding below, and provides a true vertical beam without a separate fairing block. This part number is the 12 degree tilt version, suited to hulls of 8 to 15 degrees deadrise on boats up to 9 m. An integral depth and temperature sensor is built in. The B619 uses an 8-pin Garmin connector with a 30 ft cable and plugs directly into a Garmin chartplotter or fishfinder with an 8-pin sonar port, so no separate sonar module is needed; adapter cables are available for older 6-pin and 4-pin units.

Sonar
| Sonar type | Fixed dual-frequency (not broadband CHIRP) |
| Frequency | 77 kHz (low) and 200 kHz (high), dual frequency |
| Transmit power | 500 W |
| Maximum depth | 900 ft |
Beam
| Beamwidth | 77 kHz: 45 degrees; 200 kHz: 15 degrees (at -3 dB) |
Mounting
| Mount type | Bronze thru-hull, tilted-element, near-flush (only about 5 mm of housing protrudes below the hull); provides a vertical beam without a separate fairing |
| Element tilt (this variant) | 12 degree tilted element |
| Supported deadrise (this variant) | 8 to 15 degree hull deadrise |
| Recommended boat size | Up to 9 m (30 ft) |
Physical
| Housing material | Bronze (ABYC H-27 compliant housing) |
| Temperature sensor | Yes – depth and temperature |
| Speed sensor | No |
Connectivity
| Connector | 8-pin Garmin (8G) |
| Cable length | 30 ft (9 m), with a right-angle cable exit |
Compatibility
| Compatible sounders | Connects directly to Garmin chartplotters and fishfinders with an 8-pin sonar port (for example echoMAP 50s/50dv/70s/70dv); no separate sonar black box is required as it runs from the unit''s built-in traditional sonar. An 8-pin-to-6-pin adapter is required for older 6-pin GPSMAP units, and an 8-pin-to-4-pin adapter for 4-pin echo/echoMAP/STRIKER sounders. |
General
| In the box | B619 bronze thru-hull transducer with cable, rubber hull washer, hull nut and installation instructions |

Is the B619 a CHIRP transducer?
No. The B619 is a fixed dual-frequency transducer working at 77 kHz and 200 kHz, rather than a broadband CHIRP transducer. It provides depth and temperature.
Does the B619 need a separate sonar module?
No. The B619 plugs directly into a Garmin chartplotter or fishfinder with an 8-pin sonar port and runs from the unit's built-in traditional sonar. Adapter cables are available for older 6-pin GPSMAP units and 4-pin echo, echoMAP or STRIKER sounders.
What do the 77 and 200 kHz frequencies do?
The 77 kHz frequency gives a wide 45 degree beam for broad coverage and deeper water, while the 200 kHz frequency narrows to a 15 degree beam for sharp detail in the shallows. It sounds to 900 ft.
What hull does the 12 degree tilt suit?
This 12 degree tilt version suits hulls of 8 to 15 degrees deadrise. The tilted element provides a vertical beam without a fairing block, and the bronze housing sits near-flush in the hull.
Does the B619 read water temperature?
Yes. It provides depth and temperature. It does not include a speed sensor.
