CRESSI Dive Computer "LEONARDO KS770050". I've forgotten when I purchased it. I don't remember using it, so I probably haven't, but since it seems to be out of battery, I'm listing it as "Like New". As it's been stored by a private individual, the outer box has some minor damage. Please refer to the photos for the detailed condition. ★Features★ The Leonardo is a watch-style dive computer with a slightly larger screen. It uses the RGBM algorithm developed by Cressi. The large numerical display clearly shows important information during the dive. The battery life indicator is clearly visible, and it also has an alarm function, allowing you to check with your eyes and ears, so you can enjoy diving with peace of mind. Anyone can easily operate it with a single button. It has a backlight function, making it great for night diving. ★Specifications★ ・Product Model Number: KS770050 ・Color: Black/Gray ・Size: Diameter: 67mm x Height: 27mm ・Weight: 135g ・Materials: Glass, Technopolymer, Metal Thank you. i29-20ST
