CHARLOTTE COUNTY, Fla. - The Charlotte County Sheriff's Office is hosting a laser certification class for a number of its deputies. Officers from Sarasota police department and North Port Police are also taking part. The class lines up along roads in the county and practices estimating the speed of passing traffic and then uses the laser speed detectors to confirm their findings. Sworn officers are always working to add to their certifications. Many of the men and women in the class are certified to use standard radar guns but say the lasers are more precise and technologically advanced. The 40 hour classes are held on an "as needed basis".
