It's small enough that you really don't want it to get that far away in the first place. I haven't tried mine out for distance but 300' is a good way considering that it will be a little harder to see that far away. I would think that most people generally wouldn't go more than 100' or so with it.
These little boats are hard to beat for the price especially compared to what you get from a Dept. store for the same price if not more.
