In a zoomed out view the AzShear products can draw your attention to small gate-to-gate signatures in velocity data that would be harder to see without zooming in. In the image below it’s hard to see the gate-to-gate, but the AzShear product is standing out for the northernmost couplet.
Now reference the zoomed in velocity:
Additionally, the MergedAzShear products can alert you to couplets that are occurring at low-levels nearer to other radars than are currently being viewed. For example, in CWAs with multiple radars and with limited screen real-estate due to performance and monitor limitations, it is impossible to view all radars at once. Thus you find yourself switching tabs a lot. Utilizing the MergedAzShear can tell you when you need to look at a different radar and which radar you need to look at so you can triage a storm as fast as possible. See merged product:

And note the detail you can see in northern AL and western TN. After addressing the storms in eastern MS, I know I need to switch and look at nrn AL.
