Title: S I in deep water
Post by: fishmanmike on March 16, 2010, 10:08:46 PM: How do I adjust the si and di to read detail in 80" to 140" ? This is how it currently reads. I tryied switching resolution (455 to 800) but it did'nt make a difference.

You should be getting better images than this, especially with 455khz. You should notice a big change when switching between the two.

What are your settings?
SI enhance? Sensitivity? Contrast? etc.

Is this a recording? And if so, pause the playback and play with some of the settings and see what you get.

Are all your images this dark?

As Robert suggests, recording your runs and then adjusting the settings on 'replay' is a great way to learn what works best at which depth. I do find that at extreme depth, one of my transducers works better than the other (they're both at identical angles), but as I am getting workable pictures down to 210 feet, I can't complain.
