The Whistler XTR-335 radar detector has an easy to read display and also uses Whistler's Real Voice™ technology. The XTR-335 detects POP mode radar, and features 3 city filtering modes, which allows you to adjust your tolerance false alerts.
The XTR-335 also features Whistler's dual LED alert periscope. Two blue LED's sit atop the XTR-330 and flash when you receive an alert, helping to grab your attention.
The Whistler 335 includes an Alert Priority feature, which makes sure the most important alert is displayed if multiple alerts are detected. A battery saver option turns off your detector automatically if you forget. It also features quiet/auto audio modes, tone alerts, alert priority (always displays the most important alert when multiple sources are detected), and VG-2 detection.
Whistler XTR-335 Features :
X, K, Ka, and Super Wideband Ka Detection
X, K, and Ka Superwide are the radar bands that are used by police radar guns. X band was the first band used for by radar guns, but is now the least used. All radar detectors that we carry detect all 3 of these bands.
360° Protection against all types of Laser
Unlike all of the other bands, which are wide bands, radar guns using laser technology shoot a narrow, focused beam of light to determine vehicle speed. There are several types of laser guns currently in use by police. A few of these are listed below:
- Pro Laser™ I, II and III
- LTI 20-20
- Ultra Lyte
- Stalker LZ-1
- Laser Atlanta L-1
All radar detectors that we carry will detect every type of laser.
Instant-On (Pulse) Detection
Most radar guns are constantly transmitting a signal that can be detected by a radar detector. Some radar guns have an "Instant-On" or "Pulse" feature. These radar guns will not transmit a signal that can be detected until the police officer releases the radar, which he usually will only do when his target is within range.
Detects POP Mode
POP mode is a feature of the Bee III radar gun produced by MPH Industries. POP mode will measure the speed of a vehicle in around a tenth of a second and is not detectable by many radar detectors.
The good news is that speed readings taken while in POP mode are not always accurate and should not hold up in court. MPH Industries is aware that tickets issued in POP mode would not hold up, and does not all speed measurements taken in this mode to be locked into the gun. The Bee III manual itself advises that tickets should not be issued based on readings taken in this mode.
Even with the problems with POP mode, there are thousands of these radar guns in use at this time. Because of this, it is advisable that you purchase a detector that can identify the POP mode of the Bee III.
Safety Warning System (SWS™) Alert
The Safety Warning System™ (SWS™) is an alert band that is emitted by many highway crews and emergency vehicles. Having a radar detector that monitors for this band could alert you to potential road or driving hazards. Some models with voice alerts or alpha-numeric displays have the ability to speak or display a description of the specific SWS™ warning for which you are being alerted. For example, if the alert was "Road work ahead" you would hear that message spoken if your unit supports voice alerts, and you would see that message if your unit has an alpha-numeric display.
VG-2 is a technology that police use to detect radar detectors. This is primarily used in states where radar detectors are illegal. Radar detectors that have the VG-2 Stealth feature can make themselves invisible to this detection.
Integrated Real Voice™
Voice Alerts allow your radar detector to actually talk to you. You will hear the alert spoken in plain English. This allows you to keep your eyes on the road, instead of having to look at the display or memorize a certain tone.
Some models extend the voice alerts to cover SWS alerts. For example, you would hear "ROAD WORK AHEAD" instead of having to read the display or memorize a type of tone.
Super Bright Icon Display
LED displays use lights to indicate alerts. Typically, there will be a light or combination of lights to represent each band. It is marked on the display which lights refer to which band.
A more advanced form of the LED display uses icons in front of lights. This usually makes it easier to understand the alert at a glance.
Dual Blue Alert Periscope LED's
Red Numeric Signal Strength Indicator
"Signal Strength" refers to how close the radar is to the radar detector. Most models have a way of indicating the signal strength. Basic units with only LED displays indicate the signal strength by how rapidly the LED flashes. Some models display a number between 1 and 9. Others have icons on the display to indicate the strength. On models with alpha-numeric displays, signal strength is generally represented by an on-screen bar graph.
3 City Modes and Highway Mode
City mode will reduce the number of false alarms that you will receive. There are some differences in the ways that each manufacturer implements City mode. In some cases, city mode will filter out all X band signals detected. Other units will still beep when a signal is detected, but will automatically enter Quiet mode after one or two beeps if the signal is weak.
Highway mode does not filter out any band, or automatically silence weak signals.
Audio Alert Only Mode
In this mode, the visual alert and signal strength indicator are disabled and the display panel will dim. Be sure not to turn off or mute the volume when in audio only mode!
Auto and Manual Muting
Auto muting allows you to tell the radar detector to automatically mute or lower the volume after the first few seconds of beeping. Manual muting usually means that there is a Mute or a Quiet button on the unit that will silence the current alert when pressed.
Bright/Dim/Dark Display Settings
This feature allows you to control the brightness of the display.
Vehicle Battery Saver
This feature will automatically turn off the radar detector after a set period of time. This prevents your radar detector from draining your battery if you forget to turn it off. In the case of cordless radar detectors, it prevents draining of it's own batteries.
Memory retention is available on almost all models. This means that if the unit is turned off or if it loses power, it will remember any of your custom settings.
Stay Alert Feature
The Stay Alert Feature is designed to test a driver’s alertness. Once activated, the radar detector will beep every 30-60 seconds. To show alertness, the driver must press a button within 5 seconds of this beep. If a button is not pressed, an alarm sounds.
WARNING!!! Stay Alert is NOT intended as a substitute for adequate rest. You should NOT operate a vehicle if you are drowsy. During extended periods of vehicle operation, you should take frequent breaks. Improper reliance on the Stay Alert feature may result in vehicle damage, personal injury or death. NEVER OPERATE A VEHICLE IF YOU ARE DROWSY.
Adjusts the loudness of the audio alerts on the unit.
During a self test, a unit will typically cycle through the beep for each band, and activate each light or icon on the display. For alpha numeric models, the most common messages are usually flashed on the display during the self test.
Tutorial mode simulates the alerts for each type of signal. This allows you to get familiar with the every way that your radar detector can alert you.
