SPEED

MONITORING

POpTM

Mode

pOP'"

Mode

is

a

feature

on

some

newer

radar

guns

operating

on K

and

Ka

bands.

When

the

gun

is

in

POP"·

Mode

and

activated,

a

brief

burst

of

energy, less

that

1/15

of

a

second,

is

transmitted

and

the

vehicle's

speed

is

quickly

acquired. A

detector

without

POp""

Mode

detection

capability

cannot

respond

to

this

brief

transmission.

Laser Facts

It's well

documented

that

many

radar

guns

cannot

reliably

provide

the

speed

of

a

targeted

vehicle

that

is

traveling

in a

group

of

vehicles.

In

contrast, a laser

gun

can

target

a specific vehicle

out

of

a line

of

traffic

and

determine

its

speed.

The

advantage

of

laser over radar in

terms

of

target

identification

is

the

result

of

the

laser gun's

narrow

bearn. A radar gun's transmission can

cover

more

than a four-lane

highway

at

a distance

of

1,000 feet,

compared

with

a laser gun's

transmission which covers

about

3

feet

at

the

same distance. For

best

protection,

keep

these

points

in

mind:

• Because

the

vehicle's license

plate

or

headlights

are

the

laser gun's

primary

targets,

mounting

the

Whistler

detector

on

the

dashboard

can

improve

laser

detection

at

short

range.

•

Do

not

follow

closely

behind

any vehicle you

cannot

see

through.

If you

can't

see

past

a

vehicle

ahead

of

you, chances are

your

detector

can't

either

.

•

The

receiving

range

of

your

laser

detector

will

not

be

the

same

as

a radar

detector.

Laser

guns

are

most

often

used

at

short

range.

Whistler

Laser-Radar

detectors

receive all current

laser guns which operate at a laser wavelength

of

905

+/-10nm.
