Cobra RAD 380 vs. Cobra RAD 480i: Fast Take
We suggest the RAD 380 over the 480i. Whereas the 480i affords Bluetooth connectivity by way of the iRadar app, it’s not as purposeful or user-friendly as one thing like Waze. In heavy site visitors and on the freeway, the RAD 380 performs higher and points fewer false alerts. Relating to locking out false alerts, the RAD 480i could be a bit cussed (if it locks them out in any respect). As of this writing, the RAD 380 retails for $100 on Cobra’s official web site, with the RAD 480i going for $150.
This Cobra RAD 380 vs. Cobra RAD 480i comparability information will talk about the variations between these items and why the RAD 380 is the higher alternative.
Cobra RAD 380 In-Depth: What It Presents
Final summer season, I spent three weeks driving with the Cobra RAD 380 throughout Michigan in two totally different automobiles (a small sedan and a bigger SUV). Whether or not navigating the rugged industrial areas of Detroit or the extra open expanses of I-94, the little RAD 380 was an incredible companion. It’s not a elaborate radar detector, nevertheless it does the trick.
The RAD 380 comes with a 12V energy wire, suction cup windshield mount, a hook-and-loop fastener for dashboard mounting, and a fast reference information. A carrying case just isn’t included.
Radar & Laser Safety
The RAD 380 detects all radar and laser (LiDAR) weapons from each the entrance and the rear. A small plastic piece resides on the highest left of the unit, formed like one thing you would possibly see in an algebra e book. That triangular piece is Cobra’s proprietary LaserEye expertise, which permits the 380 to detect indicators from the entrance and rear. The RAD 480i has the identical characteristic in the identical spot.
Radar Alerts & Sensitivity Settings
The Cobra RAD 380 detects X, Ok, and Ka radar bands by flashing the suitable letters on the show. A large “L” seems when a laser sign is detected. The RAD 380 can be VG-2 succesful, that means it picks up the notorious “radar detector detector” sign. The manufacturing facility setting for VG-2 is off, however you possibly can flip it on. VG-2 is unlikely to be a difficulty as radar detector utilization to your private automobile is authorized in each state besides Virginia and Washington D.C.
The RAD 380 has two sensitivity modes: Metropolis and Freeway. Metropolis mode makes the RAD 380 much less “delicate.” Put one other means, a radar detector’s Metropolis mode will make it much less vulnerable to false alerts. It’s particularly useful in city areas the place a number of X and Ok band indicators are current (like computerized doorways or site visitors signage, for instance).
Freeway mode means a radar detector is at its most delicate, making it extra apt to alert on the wide-open street. This setting provides you probably the most doable time to reply to an alert whereas driving at greater speeds, however in lower-cost radar detectors, just like the RAD 380 and 480i, it might trigger false alerts. Primarily based on my expertise, the Cobra RAD 380 does a greater job than the RAD 480i when filtering out false alerts, particularly in freeway mode.

IVT Filter
Each the RAD 380 and 480i have an IVT filter. IVT stands for “Clever Car Expertise,” and it’s a standard time period you will notice when looking for a radar detector. IVT filters cut back false alerts attributable to different automobiles with radar-based security options, like adaptive cruise management and blind-spot monitoring.
Visible & Audible Alerts
The RAD 380 will advise you of a radar band’s sign energy by way of audible tones and a numeric sign meter on the show. Completely different alert tones correspond to the kind of sign detected, together with separate tones for laser indicators. Visually on the show, the number one constitutes a weaker sign, whereas 5 is the strongest. The audible and visible alerts run in tandem. For instance, if the RAD 380 is beeping quickly, it’s most definitely exhibiting a 4 or 5 on the show. To save lots of your ears (and sanity), the RAD 380 has an Auto Mute characteristic, which kicks in after the primary few beeps.
Cobra RAD 380 Verdict
The RAD 380 is an reasonably priced radar detector with a simple, no-frills design. The short “plug and play” setup makes it an incredible alternative when you solely want a bit one thing that can assist you keep away from a ticket. There are not any apps to fret about with the RAD 380 both, so you should utilize it with out operating down your telephone battery. Nonetheless, the restricted characteristic set means the RAD 380 might be not superb for radar detector lovers who need a extra custom-made expertise with their unit.
Let’s dive into the RAD 480i to see the way it compares.
Cobra RAD 480i In-Depth: What It Presents
The Cobra RAD 480i comes with a 12V energy wire, a suction cup windshield mount, a hook-and-loop fastener for dashboard mounting, and a fast reference information. Just like the RAD 380, the 480i doesn’t include a carrying case.
Radar Alerts
The Cobra RAD 480i detects X, Ok, and Ka radar bands, together with laser weapons and VG-2. Just like the RAD 380, the 480i points a selected alert tone for every sort of radar band it detects, growing in depth as you strategy the supply. Nonetheless, reasonably than a numerical indicator just like the RAD 380, the 480i makes use of illuminated squares to indicate how shut the sign is. This is without doubt one of the elementary variations between the RAD 380 and 480i.
Show Display
The show display screen of the 480i will present alerts in line with the specified “element mode.” These modes are accessed by way of a separate settings menu. In Extra Element mode, the RAD 480i shows the detected band, sign energy, and frequency (pulse price for lasers). 5 squares signify the entire sign energy. The extra squares that seem on the show display screen, the nearer you’re to the supply of the radar.
You possibly can simplify issues by way of the Much less Element mode. Right here, you’ll solely obtain three bars based mostly on the depth of the radar alert: one for low, two for medium, and three for top.
Whereas the RAD 380 has colour indicators, the RAD 480i makes use of a black-and-white combo for its show display screen. It’s a lot nicer to take a look at and softer on the eyes, particularly at night time.
Sensitivity Modes
The RAD 480i affords two extra sensitivity modes in comparison with the RAD 380. The usual Metropolis and Freeway modes are there, though Coba refers to them as Low and Excessive on the 480i. The 2 further sensitivity modes are Medium and Auto. They operate like this:
- Excessive: Zero filtering for optimum sensitivity (greatest for freeway or open street driving).
- Medium: Minimal filtering to assist cut back some undesirable alerts.
- Low: Most filtering to scale back undesirable and/or false alerts (greatest for metropolis driving).
- Auto: When linked to the iRadar app, it adjusts sensitivity in line with your present pace.

iRadar App
In contrast to the RAD 380, the RAD 480i is suitable with Cobra’s Bluetooth-based iRadar app. With the iRadar app, you possibly can both report or obtain real-time alerts generated by a community of customers. Frequent iRadar notifications embrace pink gentle and pace digital camera areas, pace traps, and air patrols (I’ve obtained these warnings in Ohio).
Do you have to obtain an alert whereas linked to the app, the kind will present on the OLED show (like a pink gentle digital camera or pace entice, for instance). From there, a black warning bar serves as a “depend down” of types, working from proper to left. The nearer the bar strikes to the left, the nearer you’re to the user-generated iRadar alert.
By way of the iRadar app, you possibly can set over-speed reminders and handle totally different units (different Cobra merchandise are additionally suitable with the app). The iRadar app will take a toll in your telephone battery, so have your charger useful for longer journeys.



Do You Want The iRadar App?
For those who often use Waze or Google Maps, the additional cash you spend for the 480i is probably not price it. Though the iRadar app is crowdsourced, it’s not almost as purposeful as Waze. There are considerably extra customers on Waze, so the real-time alerts are prone to be simpler and useful total versus what the iRadar app can present. And since Waze can provide you with a warning to hurry traps, you is likely to be higher off saving the cash and going with the RAD 380.
For those who stay in a rural space, there are seemingly fewer customers on the iRadar app reporting the situation of various radar bands, site visitors cameras, and pace traps. Within the Iowa farming group the place I grew up, everyone already knew the “scorching spots,” which haven’t modified in 30 years. The native law enforcement officials nonetheless sit out by the baseball fields and within the Bomgaars car parking zone to catch individuals coming in off the freeway a bit too quick. If that’s the case the place you reside, the RAD 380 will just do advantageous. There’s most likely no have to depend on an app to let you know the place a radar band is likely to be coming from.
Nonetheless, in case you are a radar detector fanatic, the iRadar app is likely to be fulfilling. And there may be worth within the app when you stay in a much bigger metropolis like I do right here in Detroit. Round right here, there are many customers reporting the place radar indicators are situated by way of the app, which could be useful throughout high-traffic instances.
RAD 480i Mark Location Function
Just like the iRadar app, the Mark button on the 480i helps justify the additional $50. Whatever the mannequin, radar detectors with “Mark Location” capabilities can lock out any reoccurring false alerts by urgent a button on the unit, therefore the time period “mark.” For instance, if you recognize an space that repeatedly provides off a false alert, you possibly can “mark” it after which “lock it out” so it doesn’t trouble you once more. With the Cobra RAD 480i, you possibly can both press the Mark button on the unit or faucet a separate button in your telephone when linked to the iRadar app.
The difficulty for me was getting the Mark characteristic to work on RAD 480i. As a selected instance, the gallery under contains three images of the John C. Lodge Service Drive in Detroit, a one-way avenue that runs north and south above the faster-moving M-10. The primary picture is an aerial shot from Google Maps, with the pink arrows representing the place two totally different digital pace restrict indicators are situated (roughly). The opposite two images, additionally from Google Maps, present the indicators up shut.
On this space, you possibly can flip a perpetual circle on John C. Lodge when you drive as much as Forest Avenue, then again all the way down to Martin Luther King Jr. Boulevard. By doing so, you’ll encounter each the digital pace restrict indicators within the picture gallery above. I misplaced depend of what number of loops I did attempting to get the Cobra RAD 480i to mark and lockout each of those indicators. I imagine it took about 5 – 6 passes to get the northbound signal to lockout and roughly eight or 9 for the southbound signal.
By the way, I had the identical problem, in the identical space, with the Cobra Highway Scout. Each experiences lead me to imagine the iRadar app is marginal at greatest when locking out false alerts.
Cobra RAD 480i Verdict
Just like the RAD 380, I spent a number of weeks final summer season driving with the RAD 480i. I element this additional in a YouTube video and in my written assessment of the RAD 480i, nevertheless it takes some endurance to run this radar detector full-time. The 480i struggles with false alerts, particularly in street building zones with digital signage. In case you are between the Cobra RAD 380 and the 480i, save the $50 and go along with the RAD 380.
As of this writing, the RAD 380 retails for $100 on Cobra’s official web site. For those who nonetheless wish to give the 480i a shot, it’s also available via Cobra’s website.
Different Inexpensive Radar Detectors
Though the RAD 380 and 480i are extra reasonably priced than most radar detectors, they’re restricted of their total functionality. Relating to extra reasonably priced radar detectors, the Uniden R3 is our superb alternative. Whereas the R3 is roughly double the value of the 480i, it’s additionally twice the radar detector (with out moving into the $500 and $600 vary). The R3 tops the RAD 380 and 480i in long-range detection, false alert filtering, and customization choices.
