Overview
The Salvimar freediving buoy is a dependable default for open water training sessions. It does everything an open water buoy needs to do: stays visible, supports the line, flies the flag, and keeps its shape in conditions that degrade cheaper buoys. If you train several times a week and want a line reel built in, the Molchanovs Waypoint is the step up, and the 25L Omer buoy is the cheaper choice for lighter setups.
Why Size Matters
The 30L volume is the critical specification. A smaller buoy such as the 18L IST float technically works but pulls noticeably when a diver's body weight loads the line at depth. The Salvimar holds position. When your buddy surfaces after a 30m dive, the buoy is still floating upright with the flag visible, not half-submerged from the line tension.
The Integrated Flag
The integrated dive flag is Salvimar's practical advantage over bare float alternatives. The flag is always deployed without requiring a separate attachment, it's visible from a reasonable distance, and it doesn't require you to rig anything extra before getting in the water.
After 18 Months
PVC construction holds up well to UV and salt. On any buoy of this type, the parts that eventually fail are the inflation valve, the D-rings and the stitching on the carry bag, so rinse them in fresh water after each session and check the valve for slow leaks at the start of each season. With that routine, it is not a piece of gear that needs replacing on any typical schedule.
