# Side-Scan View
Below is a common window setup with **3D view** (left) paired with the **Side-Scan view** (right):
While side-scan data can be viewed draped over a mesh in the 3D view, the traditional side-scan view is still useful. For example, accurately positioning side-scan data in 3D requires trimming the nadir, which removes image data from the water column.
## Shared Cursor
With both the 3D View and Side-Scan View open, a white shared cursor appears in both views, allowing you to correlate features between them.
{% hint style="info" %}
You may notice a slight positional discrepancy between the cursor in the two views. This is expected, as position estimation in the **Side-Scan View** is fundamentally different from the true positioning used in the **3D View**. The **3D View** shows the more accurate position, but the discrepancy should be minor as long as the bottom is relatively flat.
{% endhint %}
## Tool Strip
In the bottom left, you will find the tool strip:
From top to bottom you have:
**Image Controls**
* Adjust the color and display settings of the side-scan image.
**Follow Mode**
* Toggles Follow Mode so the camera follows the vehicle.
**Waterfall Mode**
* Toggles Waterfall Mode.
## Context menu
The context menu shows your cursor’s coordinates, lets you add a marker, and allows you to center both the **3D View** and **Side-Scan View** at the same time so the cameras are positioned over the same feature.
