Narrative:

Departure from runway 30; I was handoff from the main tower controller to the departure tower controller. I reported my current location and the tower reply 'right turn approved'. I cleared my wing and turn at around 450 AGL; during the turn; the tower instruct me to turn left 30 degrees; I read back and comply. Seconds after; the tower told me to look for the traffic at 3 oclock; 5;700 feet. I reported in sight; but the helicopter traffic I spot is an incorrect one that was further away from me. At the time there are more than 4 helicopter training traffic in the north pattern. Seconds after; I saw a shadow passing just below my nose and passing to the right; I pull my nose up to best climb speed and I realized that was the traffic tower told me to look out for. The causes of this incident are probably the radar delay and showing the traffic was on my three o'clock but actually it is more like 11-12 o'clock because I was in the turn; and my failure to comply with the aim recommendation to turn for departure after reaching pattern attitude.
