Basic Sonar Quick Reference

1.Depress the PWR key to turn on the unit.

2.Head for your fishing grounds. Your unit automatically displays digi- tal depth and surface water temperature in the corner of the screen.

The auto settings will track the bottom, displaying it in the lower por- tion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water.

3. As you're watching the sonar returns, you can change the display by:

Zoom in to enlarge the chart for more detail: press ZIN.

Zoom out to return to full chart mode: press ZOUT.

4.If necessary, adjust sensitivity to improve chart readability. Press MENUENT and the Sensitivity Menu will appear on the left of your screen. Use ↑ and ↓ to change the setting.

Boosting sensitivity will show more information on your screen, which may cause clutter. Reducing sensitivity will filter out some informa- tion, but could omit important images. We recommend adjusting sensi- tivity until the background is lightly "peppered" — that is, scattered dots appear, but individual objects (like fish arches or bottom struc- ture) can be easily picked out of the background.

5.Watch the display for the appearance of fish arches. When you see arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart.

6.Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. Press MENU↓ to DEPTH CURSORENT. Press ↓ (or ↑) to align the cursor line with the fish arch. The exact depth appears in a box at the right end of the cursor line. To clear the cursor, press EXIT.

7.If you are drifting at a very low speed or anchored, you are not mov- ing fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom.

8.To turn off the unit, press and hold PWR key for three seconds.

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.
