It is true that in the 800 series, the DI was derived via software from the SI beam...........The Helix Gen 2 Mega units, however, do have true DI ..... The transducer in the G2 Helix 9, 10, and 12 have an all-in-one transducer that includes a dedicated DI element. This transducer in addition to the 2D, SI, and DI chirp and the new 1.2 Megahertz frequency ...results in some truly amazing images in both SI and DI. The displays in the new Helix series are the brightest in the industry and also have a VERY high pixel density.

There have been quite a few images posted in various forum and a search via google or on this forum should find a number of images to view.
