I live in the east region, and have a Lowrance Safari handheld unit. It came with the fishing hot spots sd card, but it only covers 5 lakes in MA, 4 of which i don't fish too often. The hotmaps lists more lakes, but only a couple in the HD mode. Would it make a difference to go preminum over the base, if i will only be using it on the hand held unit? Or will the 5 lakes covered in HD options be lost on such a small unit. Platinum is not an option, since it is not compatible with the handheld.
Or should i not bother at all and just use the unit to mark locations as i scout them and find structure?
