    Hi everyone,

    I have a Transas Navi-Sailor 4000, and when I select ‘M-quality objects’ lots of triangles with stars in them appear on the screen. Can anyone tell me what they mean?

    Cheers

    David

    Hy David,

    That’s called CATZOC or Zone Of Confidance and provides an indication of ENC accuracy (IHO) so if you have a triange with 6 stars it means that you are in ZOC A1 and position accuracy is +/- 5 meters.
    If you have a 3 star it means that you are in ZOC C with accuracy +/- 500 meters.
    You can simply google Zone of Confidance or CATZOC for more info.
