Whistler Pro-78SE is treated as one of the best radar detectors in its price range. It comes with great features and it is more than efficient in detecting police radars. Despite the fact this model isn’t a brand new device, it has been updated, so now it comes with improved feat2ures and several additions that the previous model didn’t have. On the other side, the price of this model is similar to the older unit, so it is still a great investment if you take into consideration that it can protect you from a speeding ticket. We were able to test this model and now we can share the detailed Whistler Pro-78SE review with you.

The main features of the Whistler Pro-78SE:


  • Laser Identifier or the LSID is the standard feature on this radar detector. In general, this feature allows you to identify which laser is in question, due to the fact the ultralight and Stalker have different frequencies.
  • Stealth mode is another great feature that allows you to avoid detection by police devices.
  • The antenna has been improved so it is much better in eliminating the false alerts and it has more sensitive Ka band frequency.
  • The display is still the same, but it offers great visibility in all conditions so it is a great part of the Whistler Pro-78SE. It can be dimmed, so it doesn’t distract you during the night.
  • Voice alerts help you keep eyes on the road, while the radar detector alerts you to possible threats. Besides, the voice is very pleasant.
  • Additional LEDs are located on the top of the device and they are more than helpful in alerting you to a treat.
  • Due to the fact it has 3 city modes, this device can help you reduce the number of false alerts.
  • Filter modes reduce the number of false alerts, caused by other radar detectors. There are 3 different modes.
  • Alert priority is a unique feature to the Whistler Pro-78SE. It means that the device will alert you to the strongest signal, in a case, there is more than just one alert on the road.
  • The automatic shutdown feature is also supported and it allows you to customize the shit down of the radar detector.
  • Quiet mode is useful if you need time without any sound. This is also a standard feature of this product.

The Whistler Pro-78SE featureswhistler pro-78se featrues a Blue Text Display, which can offer better visuals on important information that the driver needs from the device. The indicated visual confirmations are signal detected, the strength of the signal and the different modes of operation. But when the driver needs a low-key device to accompany a concealed drive, this detector automatically switches between dim and bright settings, illuminating the text display only when the lighting conditions are poor.

The ability to verify the signal is one feature that’s admirable about this product too. This prevents the driver to be falsely warned of a signal from another radar detector, especially when it’s close by. Through this, there will be less annoying warnings and notifications.

Q: Would the hardwire kit need another fuse or can I plug the positive into an empty fuse slot?
A: You can do either of those options. But if given a choice, go for an empty fuse so your amperage would not be limited.
Q: Does this device feature the new OLED?
A: No, it doesn’t. This model features the dot-matrix. (Click for a detector with a better display: https://www.ratedradardetector.org/whistler-radar-detectors/xtr-543-review/)
