Escort Solo S3

$379.99 in stock
1 used from $379.99
Last update was on: March 25, 2023 1:27 am

Escort’s familiar quality and innovation has been developed for years by experience and listening to the driver community.


The S4 is considered the latest and perhaps the best yet among their radar detectors. However, it was built on the success of the S3. The Escort Solo S3 is the slightly older predecessor in the Solo range. Make no mistake, though, the S3 is not an outdated or disappointing product. Simply, if at current the S4 is out of your price reach, then considering anything made prior by Escort would be a perfect choice.

As with the S4, plenty of the same features can be found in the S3. It features the same versatile programming options, and the OLED display is also included with the Escort Solo S3. The S3 is a battery-powered portable radar detector but also features the ability to fit an optional cord. It can detect the frequencies of all known scanners and features Escort’s discrimination technology that will prevent false alerts.

The Escort Solo S3 is also a smart device that learns as you drive, optimizing its warning system as needed to enhance your personal experience. The S3 does not shy away much from the S4 and packs the same efficient range as can be expected from any Escort detector. However, because of its slightly older design, it may not feature either wireless connectivity or the ability to detect POP signals.


  • Wide range of adjustable programs
  • Sleek and stylish design
  • Portable and compact
  • Long-range detection


  • No wireless connectivity feature
  • Slightly outdated

Escort Solo

41SP8CTGFGL | Best Cordless Radar Detector of 2021 (Review and Buying Guide)

The first portable radar detector sold by Escort was the Solo. It was considered a remarkable device and was much loved by its supporters.


The long battery life conserved by the energy-friendly circuit design of the Escort Solo was perhaps the most celebrated quality. It can give you up to 50 hours of free detection from simple AA batteries. The Escort Solo included the use of advanced laser technology that gave it far smarter detection than any competing models on the market at the time of release.

It featured the legendary long-range and is more than capable of detecting the most common frequencies. Of course, the innovation spent on the Escort Solo has long turned out of date, but for the tightest budgets, it would be the ideal choice. Even now, with older technology, the superiority of Escort’s creation still shines. The energy efficiency is a major selling point.

It may be battery powered for portability, but its consumption is extraordinarily economical and will not cost more than necessary. It may also not be connected to a wireless signal, but the integrated warning systems are designed to be efficient and versatile. Included in the software is a safety warning system that alerts the driver to any known or detected hazards.

Despite being a bit outdated, perhaps more than the S3, we would still consider it an ideal option if you are looking for the best in portable radar scanners. The Escort Solo is an ideal option as an entry-level product, or for the convenience of saving money.


  • An affordable, convenient alternative
  • Energy-saving circuitry design
  • Compact and super portable
  • Long-range sensitivity


  • On/Off button tends to wear and operates with difficulty
  • Outdated detection technology
  • No wireless connection

Whistler XTR 440

Last but not least, we have included the next best model from Whistler as our final entry. The Whistler XTR 440 is the earlier version of the other featured model, the XTR 543.


When compared to the younger model by Whistler, the XTR 440 does not fall too far short. Although it does not feature the latest technology added to the XTR 543, Whistler’s famous and beloved features are all included. After all, this was the model on which the latest innovations were added. The primary difference is only the inclusion of detecting POP signals, not featured in the XTR 440.

Pop signals is a new technology and not as frequent as one would suspect. The technology of the XTR 440 is still worth the investment and will not let you down or leave you disappointed. Included with its design is the same rechargeable battery-powered operation, as found in the newer model. It will offer up to 15 hours of operation on a single charge to provide free mobility.

As with most Whistler detectors, the blue LCD screen is a mandatory inclusion trademarked as Whistler’s clear-text communication software. It also makes use of LED lights and a mix of tones to indicate precise and accurate warnings.

With its periscope technology, it dramatically reduces false alerts and negates warnings from other radar signals like house alarms and the like. The Whistler XTR 440 is also host to Whistler’s patented cloaking technology that hides its signal from other scanners. This VG-2 feature is included in all of Whistler’s top models. The XTR 440 features the same safety warning system and pre-operation test that is adored in the latest XTR 543.

There is no need to mention what can be improved about the XTR 440 since these improvements are included with the XTR 543 at a higher cost. If you want the innovation familiar to Whistler technology, but don’t have the money to buy their latest creation, then the XTR 440 would be an ideal choice. It comes a bit cheaper but features the same efficiency and detection sensitivity that you will find in the XTR 543.

Only POP signals or more advanced radar guns may elude discovery, but as a portable radar detector, it will not disappoint. As an extra, it is sold with a one-year warranty for your convenience if the product is found to be unsatisfying.


  • High-quality radar detecting technology
  • Durable and tough by design
  • Versatile full program ability
  • Powered by rechargeable batteries


  • Technology is a bit older

Each was chosen not only for being a quality device with high standards but as ideal for various reasons. If you are on a tight budget, the older models would be a better fit. They will not disappoint and guarantee bang for your buck.

If money is not an obstacle, and you are in search of the best, try either the Escort Solo S4 or the Whistler XTR 543. Both are immaculate devices that sport the latest in detection technology. These top two models also include features that you will enjoy and benefit from. If wireless connection is an ideal attraction, then the S4 is the one for you.

If POP signals in your area are growing into a hazard, then the advancement of the XTR 543 would put you that step ahead.

One last note. The use of these devices is sold under the agreement that it will be used with responsibility. It may prevent you from getting fined, but not keeping to the laws and regulations of road safety endangers your life and those around you.
