To adjust sensitivity in manual mode:

1. First, turn off Auto Sensitivity: from the Sonar Page, press MENU↓

to AUTO SENSITIVITYENT.

2.Press ↑ to SENSITIVITYENT and the Sensitivity Control Bar appears. Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the desired level, press EXIT.

To turn Auto Sensitivity back on:

From the Sonar Page, press MENU↓ to AUTO SENSITIVITYENTEXIT.

NOTE:

To return to the original factory setting for Auto Sensitivity, see the entry in this section on Reset Options. If sensitivity is in manual mode, the Reset Options command will switch back to Auto and re- set the factory setting at the same time.

Tip:

For quicker sensitivity adjustments, try leaving the Sensitivity Control Bar on the screen as the chart scrolls. You can see the changes on the screen as you press the up or down arrows. This is handy when there's a lot of clutter in the water, and you are matching the sensitivity to rapidly changing water conditions.

Set Keel Offset

This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance dis- played by the digital depth, chart depth scale, chart cursor or fish sym- bols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the ac- tual depth is 31 feet.

On sailboats or other large vessels with deep drafts, the distance be- tween the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel.

Keel Offset lets you calibrate the digital depth: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the trans- ducer to the lowest part of the boat. In this example, we will use 3.5 feet. We enter this as a negative 3.5 feet, which makes the depth indicators per- form as if the transducer's lower in the water than it really is.

This feature helps users identify fish, structure, and thermoclines with remarkable precision.

The X125 model, while similar in design, offers a 5-inch display size. The device also features a dual-frequency sonar, allowing users to switch between 50 kHz for deep water and 200 kHz for shallow water, enhancing versatility for varying fishing conditions. Its integrated GPS allows for waypoint marking and route tracking, ensuring you can revisit those promising fishing spots effortlessly.

For those looking for advanced dual-frequency capabilities, the X136DF and X126DF models take things a step further. Both models feature a split-screen view, enabling users to monitor sonar and chartplotting simultaneously. The X136DF includes advanced navigation functionalities with an internal GPS antenna, which simplifies the installation process, while the X126DF may require an external antenna for GPS functionality.

These Lowrance models come equipped with various user-friendly features, such as customizable display settings, allowing users to tailor the information presented to their preferences. Both the X136DF and X126DF support multiple languages, catering to a global audience of boaters and fishermen.

Moreover, Lowrance devices incorporate innovative networking capabilities that allow for the interconnection of multiple devices onboard. With NMEA 2000 support, users can integrate radar, autopilot systems, and other electronics for a cohesive and efficient boating experience.

In conclusion, the Lowrance X135, X125, X136DF, and X126DF offer a fantastic mix of performance, user-friendly features, and advanced technology. Each device is designed to provide valuable insights for anglers and boaters, ensuring a successful day on the water. Whether you're a novice looking to enhance your fishing experience or a seasoned pro in search of the latest technology, these models represent a reliable choice.
