I have a helix 7 si gps kvd fish finder and I assume its an early version of the helix 7 because it doesnt have chirp. My problem is I dont really know how to use finders very well. Pretty new to them. But I really cant seem to find anything on you tube as far as before chirp helix 7 videos I can learn anything(its possible im mildly retarded)from. Is there anywhere local to Des Moines where a guy could get tutered(this is embarassing to have to ask)? I dont want to have to upgrade to a newer one when I dont understand this one. Plus if I do upgrade it wouldnt be brand new technology or the newest finder out there. So I dont wanna fall into having older technology I spent money on to not understand again. lol I barely understand the down imagery(actually I prolly dont understand that even) and dont even try the side imagery yet.
