I am going to be purchasing a 7 inch screen, side image depth finder soon and have it down to the helix 7 g2 and the lowrance elite 7-ti. From what I have read the auto chart live comes on the helix 7 gen 2 and was wondering if it is ready to start mapping how it is or will I have to buy a special card also would I have access to put the map on a computer and make a bottom hardness map? What kind of transducer does the helix 7 si gen 2 come with and how durable is it as I duck hunt and trap out of my boat in the fall and have a tendency to run into quite a bit of stuff when I am doing this, I have never broke off my current transducer which is a lowrance x135, the giant one that comes with the lowance 7-ti scares me. I kind of have a idea of what the chirp is from reading stuff and videos but how would this help the si part of the finder, does it make it clearer or just make fish stand out more? Thanks for all help you can give me if you cant tell I am new to this advanced fish finder thing.
