Overview

Escort designed the Solo cordless detector to run on batteries with no power cord, so it clips into any car in seconds. It detects radar bands and laser and shows each alert as a plain message on an OLED screen.

Cordless operation and saved settings make it simple to move between rental cars and family vehicles. Battery life and battery type are not stated, so frequent drivers should keep spares.

Who it's for

Road trippers, business travelers and drivers sharing several cars. Daily drivers in one vehicle may prefer a corded model.

Pros and cons

Pros
  • No cords to run
  • Clear OLED alerts
  • Customizable settings saved
  • Multiple radar bands and laser
Cons
  • Battery runtime not listed
  • Batteries need replacing

Performance notes

Detection range depends on terrain, traffic and how the unit is mounted with a clear view ahead. The false alert filter reduces nuisance warnings in towns. Settings survive battery changes, so swaps do not undo your setup.
