Beltronics STiR Plus is an extreme range radar detector offering enhanced capturing of the police X, K and Ka band radar guns. This is because the STiR Plus unit uses the M3 dual feed horn design of Escort. The only difference between Beltronics’ STiR Plus and Escort custom installed radar detector is that the former doesn’t include the Escort’s Laser Shifter Pro laser jammer. In fact, is a good point because you can add a better performing laser jammer like the Blinder HP-905 or the AntiLaser Priority. The advanced DSP technology lets the unit detect even the faintest law enforcement radar guns signals from miles away.

Beltronics or Bel is the sister company of Escort and it’s units are created using the same technology and platforms that Escort’s products do. This is why if you wish to get similar level of quality and benefits in a custom, remote radar detector but in low price then go for the STiR Plus model from Beltronics. In terms of technology it is equal to Escort custom installed radar detectors. It is counted among the top-rated, most reliable extreme range radar detectors as it offers 8 times more radar gun signal detection ability than the previous versions from Beltronics. It is one of the best stealth and Spectre RDD remote mounted radar detectors. Let’s find out what makes Beltronics STiR Plus so superior to others in the market.

The Beltronics STiR Plus offers the combination of advanced and user-friendly features. The Ka-Band Discerning Program lets you easily turn on/off the super wide Ka-band individually. This is a great feature as it enhances the unit’s performance against the Ka-based threats and also eliminates the need to scan and search other frequencies.

Once you understand it, you can disable other frequencies to enhance the detection range. The incorporation of TotalShield™ technology makes the unit completely invisible against all kinds of radar guns and it remains undetectable by any forthcoming threats in the future.

This is definitely a plus point as the update can be conducted on any Windows based computer running Windows Vista, XP or Win7.

Digital Signal Processing technology will analyze all incoming signals and reject all unwanted false alarms automatically. This way, you can maintain balance of long-range warning without being disturbed by false alarms. Also, the STiR Plus has multiple laser sensors, which have been strategically positioned to search for laser gun signals continuously. STiR Plus lets you enjoy next-gen laser protection including superior off-axis protection.
