Bluetooth GPS vs CF GPS
For some people there is a debate over which to choose a Bluetooth
gps receiver or a compact flash gps receiver. I have used both so
I am writing from experience. There seem to be quite a few advantages
a Bluetooth gps receiver has over a cf gps receiver.
The main advantage would be versatility, you can use a Bluetooth
gps receiver with a Bluetooth pda as well as a compatible Bluetooth
mobile phone whereas with a cf gps receiver you are limited to only
a compatible pda as mobile phones usually don't have a cf slot.
Another advantage is with regards to battery life, some Bluetooth
gps receivers have exceptional battery life lasting up to 26 hours,
some mobile phones also have a long life, although a pda won't last
anywhere near that, when using a cf gps receiver the pda battery
is usually depleted faster as the it has to also power the cf receiver
since the cf receiver can't work on its own
The third consideration is convenience, one can find some new gps
receivers that are extremely small, the holux gpslim 236 comes to
mind, because of their size and sensitivity you can stick them in
your pocket and still get a very good signal so you don't have anything
sticking out of the pda as is the case with a cf gps receiver.
Another thing to consider is that a lot of newer pdas seem to be
loosing the compact flash interface, a good example is the fujitsu
siemens loox 720, it has being rumoured that the loox 720 replacement
won't be including a cf interface. My conclusion would be it seems
that manufacturers don't consider the cf interface that important
to include in newer pdas, kind of like being phased out so it might
not be a good idea to invest in cf devices.
My final argument would be that when it comes to using a gps receiver
for driving, it is easier to position a Bluetooth gps receiver in
a convenient position where it can receive a better signal than
with a cf gps receiver because since the cf gps receiver is fixed
to the pda, you are limited by how much you can move the pda around
and still have a good view of the pda screen.
Based on all these facts I would consider a Bluetooth gps receiver
a better choice to a cf gps receiver.
