Landfall sells a similar SOS Danbuoy.
I swear they used to sell the Jonbuoy, which I think is better because it has a horseshoe separate from the inflatable
pole, whereas the MOB
grabs onto loops on the pole of the SOS and I fear may pull it down making it less visible.
The Jonbuoy seems to be widely sold in the UK.
Does anyone know where to buy one in the USA?
