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 men- tally 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.

1.Press MENUMENU↓ to SET KEEL OFFSETENT.

2.The Keel Offset dialog box appears. Press ↓ to change the plus (+) sign to a minus (–) sign.

3.Press → to the first number, then press ↑ to change the number to 3

4.Press → to the second number, then press ↑ to change the number to 5, then press EXIT. The depth indicators now accurately show the depth of water beneath the keel.

NOTE:

If knowing the exact depth of water beneath the keel is less impor- tant, you can calibrate the depth indicators so that they show the ac- tual water depth from surface to bottom. To do this, first measure the distance from the face of the transducer up to the surface (the water line on the boat). In this example, we will use 1.5 feet. This will be en- tered as a positive 1.5 feet, which makes the depth indicators perform as if the transducer's higher in the water than it really is.

1.Press MENUMENU↓ to SET KEEL OFFSETENT.

2.The Keel Offset dialog box appears with a plus (+) sign at the front of the box.

3.Press → to the first number, then ↑ to change the number to 1.

4.Press → to the second number, then ↑ to change the number to 5. Press EXIT to return to the previous page. The depth indicators now accurately show the water depth from surface to bottom.

X510C, X515C DF specifications

The Lowrance X515C DF and X510C are advanced fishfinders that cater to both novice and experienced anglers looking for an edge on the water. These cutting-edge devices integrate high-end technology with user-friendly interfaces, making them ideal for various fishing environments, from serene lakes to turbulent coastal waters.

Starting with the X515C DF, this model is equipped with a high-resolution color display that provides vivid images and superior clarity. The 320 x 240 pixel resolution enhances the ability to distinguish between different types of fish and underwater structures. One of its standout features is its Dual Frequency sonar, which operates at both 200 kHz and 83 kHz frequencies. This flexibility allows users to choose the most suitable frequency for their fishing conditions—200 kHz provides detailed readings for shallow water, while 83 kHz excels in deeper conditions.

The X515C DF also includes features such as Fish ID, which uses advanced algorithms to identify fish targets, making it easier for anglers to locate their quarry. Additionally, the unit offers a built-in GPS chart plotting capability, enabling users to navigate and mark waypoints effectively. This is particularly valuable for returning to successful fishing spots with ease.

On the other hand, the X510C maintains the high standards set by its counterpart but with a focus on essential functionalities that fit the needs of anglers who prefer a simpler setup. This model also showcases a 320 x 240 pixel high-resolution color screen and provides excellent visibility in various lighting conditions. The X510C features a robust sonar system that supports 200 kHz and 83 kHz frequencies, helping anglers locate fish and assess underwater topography effortlessly.

Both models are designed with user-friendly menus and controls, ensuring that even those new to fishfinding technology can navigate with ease. They also boast rugged construction to withstand the demanding conditions often faced by fishing enthusiasts.

In conclusion, both the Lowrance X515C DF and X510C deliver exceptional performance, innovative technologies, and features that enhance the fishing experience. With their dual frequency capabilities, high-resolution displays, and intuitive designs, these fishfinders empower anglers to make informed decisions, ultimately increasing their chances of a successful outing on the water. Whether choosing the advanced features of the X515C DF or the simplicity of the X510C, both units promise to enhance any fishing expedition.
