I am using a Lowrance HDS9 Gen 2 touch
I have been trying to map a pool on the Illinois river and I am having issues with covering all areas(forget to log areas when going out). How can I add all tracks recorded to a project and see what areas I need to still map?

Can you make routes within RM?

I am running a trail on HDS but if I was not recording at time (or run out of memory on card) Its hard to figure out where I still need to map. Just wanting to make a
good topo map for now. But eventually would like to do Sonic with Side Scan...

Thanks
