The Leakfinder by Rema Tip Top helps you find even small leaks in your inner tube or tyre. This little helper with small polystrene balls inside quickly and reliably shows you the spot where air escapes.
Yet, the Leakfinder can also be used to find punctures and holes in air mattresses, paddling pools, rubber boats and other inflatable outdoor accessories. Simply move the leakfinder over the object with the grating facing to the bottom. Once the balls start to swirl around, you have found the leak or puncture.
