Location: Mauston, Wisconsin | I have a 997SI. Yes- by comparison to a conventional sonar-> expensive. It also takes a bit of getting used to to interpret some of the data/screen displays. Especially with the chart rate/speed versus your actual GPS boat speed.
F. ex a straight concrete wall on a dam will/can look curved & underwater features can/may be distorted depending on the boat speed. However, in split mode - SI/conventional sonar, you can usually sort it out.
Even with all of that, I'd say I really like it, and it's proven it's value in my boat, i.e., versus conventional sonar.
Yes- the SI sonar puck is larger than most conventional pucks.
