Thread: Bow Mount sonar unit- SI, DI, 2d, or something else?

You guys are using 2 different calculations to get to a moniker "terminology" called ppi that doesn't even mean the same depending on which calculation you're using ...

This is from the wiki ...


This calculation to get the moniker "terminology" ppi (used in monitor measurements) is not the same as the calculation to get "total pixels in a 1 square of screen space" that Bob is calculating - but both using the same moniker terminology of "ppi" ...

Both calculations are correct - but the term used as "ppi" in each calculation does not mean the same thing ...

Regardless of which calculation used - or which term used to express the pixel density in a monitor/screen = the HELIX 10 should give better images than the HELIX 9 ...because each calculation sums higher with HELIX 10 ...
