When you want nothing but the best then you should consider the Cobra because it uses the latest technology and military grade components for its Cobra Electronics SPX 7800BT. Don’t be deceived by its looks; it is small but packed with great power. It probably has the best laser detection capacity in models in that price range.

  1. Well designed: The Cobra SPX 7800BT is well designed. The top mounted buttons make the device a breeze to use; you can’t be meddling with the device while driving on the highway or in chaotic city traffic.
  2. Super fast Sweep: The super-fast sweep circuitry enables it to cover a wide range of signals and from a greater distance than most of the other detectors.
  3. 15-band detection: The radar guns in US operate only on three radar frequencies – X-band, K-band and Ka-band. The Cobra SPX 7800BT can detect all the three types. In fact to be exact the cobra detects seven radar signals, six types of laser guns and two types of safety systems.
  4. Voice alerts: It is not possible to look at the screen when you are driving. Hence the presence of voice alerts is a relief to the driver. Unlike other voice alerts, the Cobra SPX 7800BT’s Voice alerts are not lost in radio and other background noise but are clear and intelligible.
  5. Smartphone connectivity: The highlight of the device is its Smartphone connectivity. By downloading the cobra iRadar app you can get in touch with other users. This is a matter of great convenience because through this network you can receive frequent alerts on the speed traps, speed cameras, red light cameras and any enforcement near you.
  6. Bluetooth presence: Some detectors can transfer the information directly to your phone via the Bluetooth. This helps the community of cobra users to create an interactive map and warn each other of the various speed traps, camera locations and laser guns.
  7. Can detect POP Radar Guns: The Cobra SPX 7800 BT are adept at detect the POP Mode radar guns commonly used by police. These POP Mode radar guns use a radar technology that masks the police radars from the commercial radar detectors in the market. This way they can grab the offenders without alerting them.

The lows of SPX 7800BT

Sadly, the boon becomes the bane in the case of the Cobra SPX 7800BT where the reliance on the Smartphone is also one of its biggest drawbacks.

  1. Lack of built-in GPS: The lack of built-in GPS makes all the related features to be dependent on your phone’s cellular signal. Thus if you are away from cell signals, your alerts may not be accurate. That is not all, if your phone hangs or its processor is slow the alerts won’t reach on time and the purpose of having a radar detector is defeated.
  2. Less sensitive: Another con for the Cobra SPX 7800BT is its less sensitivity to the X and K band range when compared to other detectors. But at the same time it’s city mode helps quiet down  these two bands to false alarms.
  3. Bluetooth connectivity: There are also issues with Bluetooth connectivity wherein the either the connectivity disappears altogether or it is very patchy hindering the performance of the radar detector.
  4. Glitches in the cobra iRadar app: The poor performance of the app too hinders the performance of the device.

When compared with rivals why is the Cobra SPX 7800BT better

Smartphone connectivity: Smartphone connectivity is its biggest advantage. With cellular signals becoming powerful by the day, the chances of been out of reach are few and far in between.
