Lowrance HDS unit resource usage?

[LittleGazoo]

What are the differences on resource utilization on Lowrance HDS units by AT5 Shaded Relief Imagery when the SHADEDRELIEF folder I create might contain several lake sub-folders?

Does creating a Name with the Atlas Description change resource usage?  The HDS unit will prompt to load each named lake.  Does only a "Yes" answer cause a named lake to be loaded?  Does this conserve unit resources?

Are there any other methods to conserve HDS resources?

Thanks in advance.

At5s are only partially cached until their description string is chosen.

Each At5 has it's encryption checked when the unit is turned which can take some load time.

There are plenty of ways to save resources on the At5 but, generally speaking, you just want to have a clean decluttered map and control that with the limit settings.  The more objects that need to be rendered, the slower it renders and the more resources it uses.
