Colibri Data Logger reviewed

later model LX20's have a small hatch on them to easily replave the memory
battery......without having to send the unit in to have the seals re-set
tim


Having done this with my LX20 it is pretty simple on this model. The
battery is
on a seperate screw secured pocket - as long as you ensure power
continuity when
you replace the battery you are away.

If you are unwise enough to remove the power completely (no external power
and
no 9V leads to the battery connector) you will have to return the unit to
the LX
folks in Slovenia. The reason for the batteries is to ensure integrity of
the
data stored in NVRAM, so the security info will be lost when it loses all
power.

Might be worth sending to LX for the older LX20 units anyway - so they can
be
upgraded to the new security spec. Can't speak for the other loggers.

One other point - the battery on mine was getting weak but still
functional
after 8 years. 1996 model LX20 must be one of the older ones out there and
still
going strong. With the latest firmware I even get final glide information
and a
rudimentary moving map.

The support from LX is outstanding and consistent.
