Popular white BISM dive computer. It has Bluetooth functionality and can be linked to your smartphone. - Brand: Bism - Model Name: Dive DEMO SOLIS 4GS - Bluetooth Function: Yes - Color: White - Accessories: Box, Instruction manual As of April 2025, it has 46 logged dives. I am selling it because I am upgrading. I plan to use it in Ishigaki Island in November, so the number of dives will likely increase slightly. There may be some scratches and dirt from use. I have taken good care of it, so I think the scratches are minimal. A protective seal is applied to the glass. Please refrain from purchasing if you are sensitive to used items. Thank you.
