If you are going to use a secondary (I'll answer the question instead of telling him to not use one), you can either check the gravity and transfer when the beer is done (you have reached the expected final gravity), or just let it sit for a 2 to 3 weeks and then transfer. Let ie sit in secondary for another 2 weeks or so.
Not everyone is abandoning secondaries. I tried skipping them recently and was not happy with the results at all.
