yes, Lowrance has side imaging comparable to hbirds, I'm in a facebook lowrance group and what I learned was to get images comparable to the Hbird Mega imaging you have to have the 3d module and 3d transducer.... guys were posting pics from their gen 3 hds 12s that looked pretty darn close to, if not the same, as H Birds mega imaging.... but, you have to have the 3d module and 3d transducer, which together are about 800 bux...[/QUOTE]

In using 1.2 mHz, it allows for the unit to create more refined pictures of what is below by pinging the objects below with a narrower beam that equates to more precise data. If you look below, you'll see two diagrams that break down the difference between 455kHz and the 1.2mHz MEGA frequency. Because MEGA is able to "collect more data" in the same interval as 455kHz, it is able to track and display more subtle changes in sonar returns, aka detail and target separation. You'll notice this in the first image in how we can see the changes in bottom composition and crisp shadows of the cribs and detail of things like little rocks on the bottom.[/QUOTE]

Yes, you can convert waypoints from Lowrance to Humminbird. These are a few images from a Humminbird MEGA unit. I have not seen the same level of detail without MEGA. Contrast, definition and clarity play a big part in being able to capture such images. It comes down to the fact that MEGA is utilizing 1.2 mHz, a frequency that is currently only offered by Humminbird.

In using 1.2 mHz, it allows for the unit to create more refined pictures of what is below by pinging the objects below with a narrower beam that equates to more precise data. If you look below, you'll see two diagrams that break down the difference between 455kHz and the 1.2mHz MEGA frequency.
