I'm going to use a Lowrance fish finder and I'm guessing you will be sending a Sd card but there is no information telling me what and if it's compatible with my system
All of the Lowrance units we support are right on the Lowrance page (scroll to bottom): https://fishingstatus.com/maps/instructions/lowrance
If you don't see your model, let us know and we will add it to the supported list.
