Well the money has been saved up and I am ready to buy a side imaging locator. I have narrowed my choices between the Helix 10 SI and the Lowrance 9 HDS Gen 3 (structure scan) units. Both units have their pros and seem like excellent units. They have some features the other unit does not (ie: touch screen vs buttons). Sometime later, I will be upgrading the trolling motor. I do understand that if you buy a Lowrance you have to purchase a motorguide and if you buy a Humminbird you have to buy Minn Kota. However, my concern is not the trolling motor. I can live with the features of either unit. So which way would you guys go and why. Also assume that price is not part of the picture in deciding between the two units.
