    Default GPS numbers

    When using a hand held GPS, do you just carry it all day and use the peak number? Or do you watch it as you are under way? I have a data logger that measures speed five times per second. I also have an eTrex hand held. I was amazed at the difference!

    Default Forget/re set

    I just turn it on and forget it for a while. I can re set MAX SPEED if I make any changes and want to see if it made any difference. I usually just check speed once to see that things are normal, and then stow it...

    I am using a gisteq dl-500. The constant real time numbers seem dead on. With the logger I noticed about every third or fourth run, it would peak unreasonably. After paying a great deal of attention to the eTrex I noticed it too would peak. So, if you are just using the peak you may be a over what the boat actually runs. I have ridden in a lot of 80-90 mph boats that never seemed to quite be up to par. But these guys all claimed "yeah that was with the GPS." I had always used the instant number.
    Obviously a 200mph number would be irrational! But when your 65mph boat sees 75 peak on the gps some people give in to the temptation.

    My boat went 435 mph one day while
    Boating with the family
    GPS verified. Lol
    You have to watch it not just take the
    Max speed IMO
