Bel 990 International Radar/Laser Detector.

Bel 990 International in Highway mode
This is the "dogs dangly bits", it's performance is quite simply stunning!
When I went to collect this unit from
Comtech, I was told about the relationship with Comtech and Beltronics.
The unit started life designed for the American market, but here
in the UK Gatso cameras prove a problem for all radar detectors,
the radar signal from a Gatso is very weak and gives very little
scatter. Comtech and Beltronics researched into what they would
need to do to the 990 to make it pickup a Gatso well ahead of the
competition. The result is a unit that gives a clear 8.5+ second
warning at 60mph of a Gatso in front of you, (Gatso is facing away),
this gives more than enough time to slow down, unlike the competition.
Comtech told me to switch off all
X and Ka bands leave the K and Ku on. Set the unit for quick start
and always keep it in Highway mode, so that's what I did.
In use it is superb, it sits there
doing nothing till a Gatso or speedtrap is in range, now with most
of the other units I have tried you can usually see a Gatso before
the warning goes off, but this unit has told me of a Gatso round
a corner when the radar scatter is good. The audio is clear and
can be quite loud if you want, the display is easy to read and bright
enough to deal with the sun on it. It sits on its suckers and bracket
well with little vibration.
When you approach a Gatso it goes
from saying "HIGHWAY" in the display to giving the frequency of
the Gatso with a beep then it turns into a field strength meter
a male voice tells you which band it has detected then still making
the beeps which speed up as you approach the Gatso.


Frequency mode. Field Strength
mode.
So what tests did we do?
The most important one is the Gatso Test. We have a
section of road that we use for all Gatso tests, it has one of the
lowest radar scatter fields making it more of a challenge to Radar
Detectors it also allows us to do the national speed limit if we want
to. All the Radar detectors are tested in the same vehicles and in
the same position on the windscreen.
The Bel 990 was subjected to three passes
using a stopwatch to time the unit from the first beep to the point
of passing the Gatso to establish an average warning time . Speed
was 60mph. Please note warning times can vary subject to conditions.

Times for the Gatso Test. M25 Gantry Gatso.
Important Note: The Gatso Used
was a solo Gantry Gatso on the M25 Motorway. Speed was 80mph
We had the information confirmed by a contact in the Met that no
other Gatso was working within 2 miles, this is important since
another Gatso near the area can effect the results in a major way
since they are mounted so high.
Laser Gun Test.
The Laser gun was used in two ways,
the first test was directly at the car with the detector in it,
although the detector worked and was instant on alarm, if the officer
used the first reading you were in trouble. However they often take
a few readings so you may have a chance to slow. The second test
was to have two cars in front and the operator target the first
car and see if there was enough scatter for the third car to get
an alarm, it was not a problem for the Bel we had an alarm in all
three runs.
In our opinion you could get a warning
or you could get nicked when it come to the Laser alert mode.
False Alarm Test.
This is done over a six mile selection of roads taking
in two Gatso's and a town centre with Banks, Supermarkets and DIY
stores.
We had three alarms on the K band and
none on the X band (X band can be turned off on the 990) The amount
of false alarms is important, if it spends all its life beeping
at you, you will soon start to ignore it. The amount we got was
much lower than the other units tested.
Can we recommend it, YES, we can, it is the best
so far.
