Doose... I believe the Solo uses the older software and it's sensitivity is lower than the 8500, let alone the 8500 X50.
Motor Trend's latest article puts the Escort 8500 X50 and the V1 neck-and-neck, but the Escort 8500 X50's new software edges out the V1. Here's the summary from the article:
Escort Passport 8500 X50
(94.9 points)
Top Protection Dashtop Radar/LIDAR Detector
The Passport 8500, with its high-sensitivity, state-of-the-art POP mode capabilities, small size, and high-quality construction, remains at the top of the pyramid for overall radar and LIDAR detection. With its optional ZR3 laser shifter ($500 MSRP), it's the lone high-end detector offering the ability to legally interrupt most laser guns, making it the choice in laser-rich driving environments.
WHAT'S HOT · Available optional plug-in laser countermeasures, with POP mode protection
WHAT'S NOT · X-band performance falls just a bit short of leader
BOTTOM LINE · Remains the gold standard in radar/LIDAR dashtop detectors
Price: $299 (manufacturer direct) Escort: 800/433-3487
Valentine One
(94.8 points)
Although the external case has remained basically the same through the years, the Valentine One V1 is a top-flight instrument to detect all bands of radar as well as LIDAR. Owners swear by the effectiveness of its front-panel direction arrows. While it offers the highest level of sensitivity, its level of user-friendliness, overall protection, and value falls just a bit short of competitive units.
WHAT'S HOT · Designates direction of the threat; high sensitivity in all bands
WHAT'S NOT · Less POP mode sensitivity, size of case
BOTTOM LINE · Great protection overall, but at a premium price.
