Airmar R111LH – sonda zanurzeniowa 2 kW CHIRP (38–75 kHz / 130–210 kHz) + temperatura – (przewody gołe)

The Airmar R111LH transducer is a 2 kW dual-band CHIRP depth and water temperature sounder. It operates on low frequencies from 38 to 75 kHz and high frequencies from 130 to 210 kHz, providing an extended coverage of 117 kHz bandwidth. Installation is either oil-filled or in a "pocket" mount configuration. It is optimized for solid fiberglass hulls.

The Airmar R111LH transducer uses two distinct CHIRP frequency ranges:

A low frequency from 38 to 75 kHz.
A high frequency from 130 to 210 kHz.
This full coverage provides a 117 kHz bandwidth.

Yes, the Airmar R111LH transducer is equipped for water temperature detection in addition to depth.

The R111LH transducer can reach maximum depths of:

1829 meters (6000 feet) at low frequency (38-75 kHz). 457 meters (1500 feet) at high frequency (130-210 kHz).

The dual-band CHIRP means the depth sounder operates on two separate frequency ranges (low and high) simultaneously or alternately. For the R111LH, this extended coverage with 117 kHz bandwidth provides improved target detection, more precise bottom discrimination, and clear separation between baitfish and gamefish.

The beam widths of the Airmar R111LH transducer vary depending on the frequency:

At low frequency (38–75 kHz): from 19° to 10° (port-starboard) and from 10° to 5° (bow-stern). At high frequency (130–210 kHz): from 8° to 4°.

Yes, thanks to its advanced CHIRP performance and wide bandwidth, the Airmar R111LH fishfinder provides excellent seabed discrimination and clear separation between baitfish and gamefish.

The Airmar R111LH transducer is designed solely for solid fiberglass hulls. It cannot effectively transmit through core materials such as foam or balsa wood.

The Airmar R111LH transducer is designed for an "in-hull" installation (inside the hull), specifically in an oil bath or "pocket" mount. For the oil bath installation, it is placed in a reservoir filled with propylene glycol, secured inside the hull.

No, the Airmar R111LH in-hull transducer installation does not require hull drilling. It is mounted inside the hull in a liquid-filled tank.

When choosing the location, ensure that:

The fiberglass hull is solid (no air bubbles or core materials).The area under the transducer will always be in contact with water.The water flow under the hull is as smooth as possible, with minimal bubbles and turbulence.The transducer beam will not be blocked by the keel or propeller shafts.The location is away from interference sources (propellers, other machinery, other sounders, cables).The area is cool and well-ventilated, away from the engine compartment to prevent overheating of the liquid.

For the oil bath, it is recommended to use propylene glycol. This is a non-toxic antifreeze/coolant suitable for marine applications and recreational vehicles (RV).

The maximum acceptable deadrise angle for installing the Airmar R111LH transducer is 12° on the long side of the tank and 22° on the short side of the tank.

To mount the depth sounder transducer to the hull, recommended bonding materials include fiberglass resin (such as Bondo 401 or West Marine #1937762), Marine-Tex epoxy putty, or 3M™ Marine 5200 adhesive/sealant.

Yes, CHIRP transducers such as the R111LH generate more heat than traditional transducers. Incorrect installation, particularly in a hot area like the engine compartment, or if the transducer is not fully immersed in liquid, can lead to overheating and probe failure. The liquid temperature in the tank must not exceed 60°C (140°F).

The Airmar R111LH transducer is supplied with bare wires. This means it does not come with a pre-installed connector and requires proper wiring and termination to connect to your equipment.

Yes, the Airmar R111LH transducer is recommended for high-speed boats, provided it is installed in an area where the water flow under the hull is as smooth as possible, with minimal bubbles and turbulence.
