It would be a great help. It’s rated for 30 minutes in up to a meter of water. So basically… if you fall overboard with Spot on your belt or if your motor blows a head gasket or even if the boat capsizes… as long as you’re conscious and afloat, Spot will get you help. And the great thing is — with the $8 insurance, there will be no huge $10,000 bill afterward. You’re extracted… safe… covered.
