Ok...maybe a dumb question. For 2D displays, why does the Lowrance images look so much 'sharper' than the Humminbird? Is there a reason a specific reason Humminbird does this - are they cheaper displays, or is HB trying to show more detail or something? I've always been a Lowrance 'guy', and I'm having a hard time convincing myself Humminbird has improved over the year....but I'm trying!
