    Gulfman accuracy report and Mudman vs Gulfman

    Greetings all,

    Just want to report that after a bit of fiddling and investigation that the Gulfman seems spot on with the moon phase and tides both at current time and scroll ahead date and time.

    I think the most important thing is to determine as accurately as you can the lunatidal interval for your location. Longitude can be found on a google search for your area.

    You can also search the internet for lunitidal locations near your area then fine tune to match the location you specifically want.

    I have recently bought a mudman and gulfman at the same time so offer a few thoughts for those wanting to buy either or both.

    Gulfman

    Like;

    Recessed protected face.
    World time
    Titanium screws and back
    Wide band suits thickness of case

    Don't like;

    Stopwatch reset as button A
    Red 'G' on bezel

    Mudman

    Like;

    Very comfortable back and strap, the best of the G shocks that I have tried
    Tough buttons which feel secure and sealed
    World time
    Long timing stopwatches
    Like the proportions of the watch, was worried it would be too big but smaller than my PRG-40
    Recessed face

    Don't like

    Red buttons are either love or hate gray might have been better
    Time movement graphic hard to see / waste of space
    Flash alert graphic area could have been an lcd icon like mute etc, waste of space

    Gulfman seems a bit more conservative than the mudman but love them both they are better than I had expected.

    Scott.

    One more for the Gulfman: why did they make the strap so short? The Mudman strap has plenty of length, but the Gulfman seems to have gotten the short end of the stick.

    Thanks for the info re lunitidal data. The only problem I have found is accurately setting the longtitude as it only does it in increments of 1 degree, where I am it it 0.33 degrees. I suppose I will have to set it to 0.00 - London

    That aproximation means you'll have a 20 seconds error in moonphase and lunitidal calculations, way bellow the resolution you have in the data shown.

    Hi Paulo

    Thanks for the update. I am afraid I am very ignorant of all things tidal etc. Am I right in thinking that each degree is equal to a minute?

    The general watch setting for the UK (London) is UTC 0.0, Longtitude 0 degrees East with an Interval of 1.10

    Have I got this right??? -

    My nearest port is Littlehampton which is 0 degrees 32minutes West with an interval of 11.08.

    So - I have set my watch with UTC 0.0, Longtitude 0 degress East with the Interval set at 11.08 and according to your last post my watch should only be about 20 seconds different to that of the predicted tides.

    Cheers
