Spoke to someone who said they are reading bottom at 600 feet on their raymarine system.
Looks like the Garmin downvu only goes to 300 feet.

Looks,like it would be a huge advantage in bottom jigging in 350 - 500 foot of water.

600' is the limit to see bottom under optimum conditions. Don't expect any details at such depths.

The screen shot below is from a test done by Raymarine Norway taken wintertime in a clear fjord here in Norway.

For 600' ...I think a narrow cone traditional sonar is still the best option...vs structure structce scan

Unlike others who are guessing, I've used it to three hundred, and I have seen screen shots off the west coast to beyond six hundred. I'll see if I can dig up some screen shots.

Seeing bottom is no problem. If a bait ball exists, you'll see it.
