A double is as we know the bet on two consecutive winners.
It's different from an accumulator in that it has it's own pool and usually pays more than the accumulator of two winners, because there is only one house take whereas in the accumulator there are two house takes,
But it is offered only for consecutive races.

An open double is when we make a selection for the first race (first leg) and we wait until after the first race to make the second selection, provided of course we have won the first leg.
This gives an advantage because we can see the horses in the paddock before we select in both the first and second legs, as well as observe any significant totalizator movements, etc.

Question: Are open doubles available in the US race courses ?

The open double has the following disadvantage for the race course operators:
They have to deploy terminals and human operators to make the first leg-second leg changes. Those terminals and human operators do not make any money during the transaction of changing the tickets, so they are tempted to phase them out and opt for the closed double.

Is it however possible to construct an unattended sort of terminal, possibly wall mounted, where people can make those changes ?
I 've seen such things -not quite the type- checking lotto tickets.

Is there such a thing anywhere and how much does it cost ?
