Whistler XTR-420 Pros/Cons and My Thought

The Whistler XTR-420 is a battery-operated radar detector that was released in 2010. It is a discontinued model, but it can still be found for sale online. The XTR-420 has a number of features that make it a good choice for drivers who want to be alerted to radar and laser speed traps.

Pros:

  • Multi-band detection: The XTR-420 can detect radar signals in the X, K, and Ka bands. This covers the majority of radar guns used by law enforcement in the United States.
  • VG-2 and Spectre modes: The XTR-420 has modes that can help to protect it from radar detector detectors (RDDs). RDDs are devices that law enforcement officers can use to identify radar detectors.
  • Dual alert periscopes: The XTR-420 has two alert periscopes that provide visual alerts when the unit detects radar or laser signals. This can be helpful when you are driving in a noisy environment or when you want to be alerted to radar signals without hearing an audible alarm.
  • Icon display: The XTR-420 has an icon display that shows the type of radar signal that has been detected, as well as the signal strength. This can be helpful in determining the distance and direction of the radar source.
  • Built-in battery charger: The XTR-420 has a built-in battery charger that allows you to charge the unit's batteries in your car. This is a convenient feature if you plan on using the XTR-420 on long road trips.

Cons:

  • Bulky: The XTR-420 is a relatively bulky unit. This can make it difficult to mount in some vehicles.
  • Short battery life: The XTR-420's battery life is only about 4-5 hours. This means that you will need to recharge the batteries frequently if you plan on using the unit for extended periods of time.
  • Occasional false alerts: The XTR-420 is known to generate occasional false alerts. This can be annoying, especially if you are driving in an area where there is a lot of radar activity.

User reviews:

Overall, user reviews of the Whistler XTR-420 are positive. Many users praise the unit's ability to detect radar and laser signals, as well as its VG-2 and Spectre modes. However, some users have complained about the unit's bulkiness, short battery life, and occasional false alerts.

My thoughts:

The Whistler XTR-420 is a good choice for drivers who want a radar detector with a variety of features. The unit's multi-band detection, VG-2 and Spectre modes, and icon display are all useful features. However, the unit's bulkiness, short battery life, and occasional false alerts may be drawbacks for some drivers.

Overall, I think the Whistler XTR-420 is a good radar detector, but it is not the best option on the market. If you are looking for a radar detector with the latest features and technology, I would recommend considering a newer model. However, if you are on a budget or you are looking for a radar detector with VG-2 and Spectre modes, the Whistler XTR-420 may be a good option for you.
