Just purchased a Helix 9 Si for my console and a helix 10 sonar GPS for the bow. I had been all over the place on what I wanted for electronics but the Helix units price point and autochart live sold me! The Helix can store up to 8 hours of your own mapping out of the box, if you need more time theyre saying you need to buy a memory card. This is where I got confused which card do I need to buy, MOST of my local lakes dont have charts so this will be huge for me on all the 500 acre or smaller lakes I fish. I just want the chip that stores the info I got confused was with the options of the zero line chip etc. etc.thanks in advance!Last edited by 94eyracat on March 26th, 2016, 12:58 am, edited 1 time in total.
