Again quite easy
Hit the first take and play the fish, when the second goes hit it lay the rod on the ground with the bail arm open.
Then, get on your knees and pray to God, Alah, the Sun and the moon and any other god you can think of for your good fortune, TWO takes, I should be so lucky.
Also what some people do is set up two landing nets if theres a chance of double hook ups. Then you can just net the first fish then go straight to playing the other and then using the other net. It just saves having to unhook the first fish or trying to net the second fish with a fish already in the net.
