The only issue I have about the SI units I have/had is (and still is) the slow refresh rate of the chart screen (so called slow gps response).
The gps is dead on accurate.
You can purchase the new units with the high accuracy gps receiver (so called antenna). I do not own the new antenna, but I have read the manufacturers specifications for the gps receiver chip sets. These are really good and accurate receivers for the money. However, the new antenna does not solve the refresh problem.
You can adjust to this problem by trial and error on the water and figure out a personal strategy that overcomes this inconvenient problem.
Humminbird is aware of this problem, yet continue to conveniently ignore the facts. My emails go answered about the response. No one in customer service is willing to talk about it. The CS folks seem "surprised" when/if asked about the response issue. Like Yiikes said, they got their head in the sand.
By no means do I regret buying the units. I am just disappointed by attitude of monopoly.
If it is truism about Lowrance SI, then this might be the stimulus HB needs to get their head out of their butts and fix this issue.
Also, I feel sorry for the CS agents that have to deal with me. I ask too many questions. Sometimes it is hard to separate BS from facts.
It is your decision, not mine.
I am waiting on the Lowrance......Shop around.
