As I'm still very much in learning mode I did a 10 mile walk around Fleet Pond and further in Hampshire today (beautiful sunshine).

I was using the large breadcrumbs to plot the walk as I did it but couldn't understand why they weren't always following the route that I took. In many places it merely showed a straight line (for example across the lake when of course I walked around it).

Would someone offer an explanation please ?

Does it do this if the sat signal is lost under trees ?

Are you turning the SatMap on and off?

Hi,

How were you carrying the GPS? Were you watching it at the time that it wasn't tracking?

The (somewhat directional) internal antenna needs "a good view of the sky". Tree trunks (there can't be too many leaves at this time of the year) and in particular your own body can block the signals. It may also be necessary to keep other electronic equipment (e.g. a mobile phone) some distance away.

Cheers, Alan.

My experience is very different to yours.
My SatMap gives a strong and accurate reading in my study at home, where my TomTom and an old Garmin fail to get anything at all.
My SatMap has never given me a "duff" signal, even deep inside woodland. It once "wandered" a little by about 100m when in a deep canyon in the mendips, but that is all. I carry mine in the bottom of a camera bag (lots of lenses and bodies overlaying it) or in my trouser pocket without loss of signal.
I suspect your aerial may need tuning. A return to SatMap is needed for that.

Many thanks to all for the responses.

So as to be a little clearer I should explaIn:

Power Control:
Auto Power Saving ....... OFF AFTER 5 MINUTES
AUTO SCREEN ........ OFF AFTER 3 MINUTES
Screen alerts every 3 minutes

Advanced Power Control:
Power Saving Mode set NORMAL
Hibernate TImeout 1 hour

I was carrying the unit in my pocket occasionally retrieving it to check the position. Of course each time I took it from pocket I needed to switch ON again !

At times I looked at the GPS screen but to check for more distant direction switched to planning screen - then back to GPS and into pocket (still switched ON)

I had hoped to set the walk to track and then store it for future use but as the bread crumbs are not a true reflection (ie I might think that the direction indicates that I need to swim the lake !) this is not that useful

Perhaps my settings are not correct ?

question how did you switch it on.
did you just press a button on the sides or foot of the screen OR
did you press the on/off button?
if you press any of the buttons mentioned on the second line it should wake the machine from its slumbers IF i remember correctly- show a position and breadcrum trail
then after your time interval (3mins) go back to 'sleep' until activated yet again at your command by button press.

To record a continuous track the unit must remain on Smile

Change your settings to these:

Power Control:
Auto Power Saving: Always On

Power Saving Mode:
Hibernate Timeout: Off

The other settings are fine although you might like to tweak them to improve battery life.

Cheers

Thanks to all - your comments VERY much appreciated.

I have read a now re-read the power instructions and have a better understanding.

Of course I've also taken Neil's specific settings advice and realise that I will now be more in control when I hit the track again.
