Hello,

Here is what I have... I have two boats. One is full size and one is a 10' bass raider. On the big boat I have two Lowrance Elite 7 HDI's. On the small boat I have one Lowrance Elite 5. (Not HDI) This unit does not have sonar logging capabilities.

I use the small boat on a 35 acre private lake (HOA) that was specifically designed as a bass lake. It has a lot of bottom contours and structure. I want to map this lake.

If I temporarily move one of the Elite 7 HDI's to the small boat and map the lake, would the Elite 5 be able to read the micro sd card with the map saved to it. The 7's are on update 4 and the 5 is on update 3.6.

Thank You,
Bryan
