Like new ProChrono DLX CEI-3820 Chronograph from Competition Electronics complete with box, skyscreens, manual and extra battery box door. Essential tool for accurate reloading/load development. I've owned, shot over and through Pact, LabRadar and multiple versions of this companies offerings side by side. All 3 measure the velocity just as accurately at the instrument and these CEI's are much easier to carry, handle and use in the field. This unit was used twice and is like new. I'm in the Greenway Rd and 32nd St. area. Text 602 eight03 eight 3 eight 4. Will ship on your dime.
