hey guys,
i have a Humminbird 1198c SI Combo unit up by the dash as my main sonar. i just noticed the auto chart zero lines card available on the humminbird website. my question is, can i use this to map out my lake? i always thought i needed a newer unit to be able to auto chart, but i've been reading that guys are using this card to chart lakes with 800 and 1100 series units, is this possible? if so, did humminbird come out with a software update to make this possible on older units? i've always wanted to chart my lake out, but i couldn't just purchase another unit just for this feature.
any help would be great!
Thanks,
Zildjian
