Cobra SPX 7800BT

Written by Chelsea Woods. Posted in Reviews

Cobra SPX 7800BT Radar Detector is a very useful instrument that can help drivers escape unfortunate situations where they would have to pay considerable amounts of money for speeding tickets. Besides impressing with its overall performance, this device features a practical design that allows users to place it wherever they want, as it won't distract their attention. It is almost half the size of similar products that you can find on the market, and it is also very sleek and stylish. Furthermore, this product is one of the few radar detectors that integrate military grade components, so you can see it as a unique tool that can detect threats with a high precision. Efficiency Giving the fact that radar guns in the U.S. function only within 3 radar frequency bands, you will be more than surprised to find out that the Cobra SPX comes with an extra feature that implies a 15-band detection. So, besides detecting X, K and Ka bands, this device can offer you extra protection against a different band that includes 3 types of signals, radar, safety systems and laser. Within these, it identifies six brands of laser guns, seven signals of radar, and two safety system signals. Although in the U.S. radar guns operate only X, K and Ka band frequency ranges, the addition of the  Ku-band can be very effective, especially if you decide to visit Europe some day. Europe is the only country that uses the Ku-band, but there are many opinions according to which this band will be in the U.S., too. So, it is better to be ahead of the game than finding yourself unprepared for certain situations. The only disappointment that you will find in this product is that it doesn't integrate a GPS system, which means that you will have to rely on your smartphone in order to enjoy the features delivered by this application. Keep in mind that if your phone doesn't have a reliable processor, it can slow down your detector's ability, and you might not get enough time to slow down and adapt your driving to the required standards. Alerts The Cobra SPX 7800BT can connect through Bluetooth with your smartphone, which enables it to provide location-based alerts. Giving that this unit comes with a national database for Red-light Camera, AURA Speed, Dangerous Intersections, and Known Speed Traps, you can be confident that you will obtain a great precision, and that you won't have to deal with unpleasant situations. Still, if your smartphone's battery dies, you won't get the chance to be warned about threats that laser and radar detectors can't recognize. However, this product can deliver a reliable performance, as it integrates a display with bright graphics for displaying visual alerts, and it features the capacity to deliver voice warnings through an above-mounted speaker. Most customers appreciate it for quiet and less stressful sounds, and for the fact that its voice alerts can be easily understood.

GOOD

The only thing that we didn't like about the Cobra SPX 7800BT Radar Detector is that it doesn't come with a GPS system. Still, you can use your smartphone to obtain the same benefits that a GPS would offer you. Therefore, you need to make sure that your phone has a reliable processor, otherwise it might decrease your detector's performance.

Cobra SPX 7800BT Radar Detector is a very useful instrument that can help drivers escape unfortunate situations where they would have to pay considerable amounts of money for speeding tickets. Besides impressing with its overall performance, this device features a practical design that allows users to place it wherever they want, as it won’t distract their attention.

Efficiency

Giving the fact that radar guns in the U.S. function only within 3 radar frequency bands, you will be more than surprised to find out that the Cobra SPX comes with an extra feature that implies a 15-band detection. So, besides detecting X, K and Ka bands, this device can offer you extra protection against a different band that includes 3 types of signals, radar, safety systems and laser.

Keep in mind that if your phone doesn’t have a reliable processor, it can slow down your detector’s ability, and you might not get enough time to slow down and adapt your driving to the required standards.

Alerts

The Cobra SPX 7800BT can connect through Bluetooth with your smartphone, which enables it to provide location-based alerts. Giving that this unit comes with a national database for Red-light Camera, AURA Speed, Dangerous Intersections, and Known Speed Traps, you can be confident that you will obtain a great precision, and that you won’t have to deal with unpleasant situations. Still, if your smartphone’s battery dies, you won’t get the chance to be warned about threats that laser and radar detectors can’t recognize. However, this product can deliver a reliable performance, as it integrates a display with bright graphics for displaying visual alerts, and it features the capacity to deliver voice warnings through an above-mounted speaker. Most customers appreciate it for quiet and less stressful sounds, and for the fact that its voice alerts can be easily understood.

Overall performance

This Bluetooth-enabled radar detector provides enough features to help you avoid costly tickets, and even without a smartphone, it delivers a great range and a decent accuracy. However, when connected to your phone, it gives you access to the Cobra iRadar application, which allows you to share threats and valuable information with a large community of users. The best part about this application is that besides alerting you about speed traps, red-light camera, and speed cameras, it informs you about the places where police officers are using laser guns. Since laser guns are usually undetectable, the radar can’t recognize them in advance without receiving warnings from other users. So, the community sharing option is very effective and reliable. Plus, this device features a very fast circuitry that offers extra detection range and the best warning to radar guns, including super-fast POP Mode Instant-on Radar guns.

Ease of use

Giving the fact that the OLED Display offers an exact indication of the detected signal, and that it shows the current mode of the unit, you can be confident that you can use your detector easily. The device’s design features a power button and a volume knob on the left side, and a detachable suction cup-based support that attaches to its top back. The Cobra SPX includes a black power adapter, but although it incorporates four buttons, none of them are for Bluetooth connection. Therefore, you will have to connect your detector with your device manually, which is very simple and fast. The detector’s screen is easy to see in direct sunlight, while its on-screen menu features automatic muting and sound calibration options. Although the speakers might seem too small, they are acceptable for delivering sound in a regular car cabin.

Technical details

Since it measures only 3.7 x 2.4 x 1.5 inches, and it weighs 11.2 ounces, you can imagine that the Cobra SPX 7800BT has an ultra compact design, which makes it one of the smallest radar detectors on the market. This discreet and refined product is backed up by a 1-year warranty, and there are stores which offer a 60-day guarantee. So, besides paying only $160 to get this remarkable unit,  you will have plenty of time to find out if it meets your needs. Furthermore, if you discover that it doesn’t suit your expectations, you can return it, and you will get your money back.
