150 miles everything looks normal. At 100 miles, the top half of the

the same area of land. The terrain stops at N 60deg 00'03.3"

I'd like to know if they have a problem with the software.

Exactly. There are large areas in Alaska with this problem. I know that
where I fly (around SXP, AUK, PAEM), this problem is widespread. I have
found that the zoom level at which terrain disappears depends on which view
you are using and what setting you have for "earth detail". If I set it on
low, it will allow me to go to a closer zoom level than if on high.

OK, I've looked again at my unit. At 150 miles range on earth detail=high,
all looks normal. At 100 miles about the latitude given above is a green band
separating detail topo information from less detailed. Above this green band
is detail but of very low detail, such as lakes, a MOA, rivers, etc., but
not in great detail. If you scan to the east and west, you will see that
this effect continues. I'm convinced this is a database, hence file, problem
and nothing is wrong with any of our units. It appears they simply don't
have the detailed topo info in the database for close work above that
latitude.

Incidentally, on earth detail=medium, this changes on mine at 60 miles, and
on 'low' at 30 miles. If I turn off the earth detail, all above that green
band goes white, other than the MOA and airports, etc.

Still, I believe this is a database problem. Lowrance tech support has been
helpful to me in the past, but don't know their policies now. Still could be
a simple download of the new data might work. If you call, tweak them to
tell you the dates of the database on the unit at which they are looking and
have them set up the unit as you have yours set up. I would be interested in
the results.

I emailed them again and will see what they say.

Jackal24,

If
you have one, can you try zooming in to the airport 5NN and seeing if your
unit shows the problem. At a close zoom level on mine, you can see the
terrain disappears on part of the screen.


I'm afraid I only have access to International units (see www.aeroversand.eu)

Thanks for posting their response. I upgraded my firmware once, but will
look for a new update on their site.

No problem. I hope they fix it soon.
