The proxalert isn't even a competitor. It is made by some guy in
France, and has little support or credibility.

The trafficscope is made in the US and has a lot more support.

As far as power, the R5 is only good with ships powr and to 12 volts.
Very limited compared to the trafficscope which is battery or up to 40
volts.

The aviation consumer article was written by a rival of Surecheck
named bertorelli, and thus isn't a real comparison in my opinion.

For the price, people can get a Trafficscope for $985 which is less
than the proxalert which has many bugs from talking to a couple of
pilots who have tried it.

Hi,
Aviation Consumer finally evaluated the Proxalert R5
proximity alerter
and what they say is crystal clear : 'It has better
performance and
features' than other devices and 'The R5 is the easy
winner over
Surecheck' trafficscope.

Those interested could buy a copy of the article at
www.aviation-consumer.com'

As one of those who is sceptical about such devices
for glider use, I have looked the following web page
which gives details of the device

http://www.avionix.com/collis.html

To try to keep my comment brief I have cut and pasted
relevent bits, to get the full descrition look at the
web pages

'TrafficScope is a completely self-contained passive
collision avoidance system designed to indicate and
alert traffic around your aircraft. TrafficScope VRX
displays the three most threatening aircraft with digitally-precis
e range'

'The system listens for transponder replies from aircraft
in the area and derives altitude and range information
on-the-fly. When target aircraft are interrogated by
ground radar or any other active system, such as TCAS,
the transponder responds with range and altitude (Mode
C) information.'

'All transponder-equipped aircraft will be displayed
on the easy-to-read, backlit LCD display, along with
TCAS-style warning indicators, and professionally-recorded
audio alerts indicating traffic threats.'

There is a place for such a device, but in free airspace
unless we are all equipped then such a device could
be as much a danger as help. It could lead some to
fly in the belief that they are safe, especially when
the sky gets busy.

It is however a start, but have you seen the price!!!!!

What's the cost of a mid air collision ???

According to Aviation COnsumer the Proxalert R5 has better
performances and features than the Surecheck Trafficscope. Considering
a usage in a glider
the R5 power consumption is very low (1 watt) compared to 5 watts for
the Trafficscope. Last but not least the R5 displays simultaneously
the three closest threat including code and trend. Have a look at the
Trafficscope display and you will see by yourself that there is no
room to display the info of these three threats.
