As far as the new Lakemaster chip is concerned, I used Guys last Sat and found it contained Too much information. Terribly cluttered with stuff we really didn't need . Maybe set up wrong.
Admittadely, the new Humminbird Onix, together with the new/revised LakeMaster chip tends to give one a LOT of information to digest, and it takes a few trips to get use to having that much information at the touch of a finger, but honestly; CHIRP, chip, gen 1/2/3, or anything else that the competition has does not begin to compare with the overall quality of performance and picture that the Onix/LakeMaster combo offers. BUT....this setup is not for the first time/inexperienced electronics user, as it takes a lot of on-the-water experience to obtain the full capabilities that it offers (and that setup is not cheap either). I've now had my new Onix 8 & 10 for about three months and am finally getting comfortable with knowing what to do in a given situation. And I do wish that I had gotten both units with 'touch' instead of just the 10.
IMO, know your own level of electronics knowledge and buy accordingly, but strongly consider the Onix/LakeMaster over anything else if you're gonna go "top shelf". If anyone has any questions, please let me know and I'll try to help.....and I'm NOT sponsored by either of these products.
