A helicopter pilot was beginning a tour of the hoover dam when he caught sight of another helicopter about 500 feet away. Aircraft Y pilot asked aircraft X pilot if he saw him but the aircraft X pilot stated that he was surprised and did not respond. Aircraft X did a 360-turn to allow aircraft Y to precede him and reported that he incorrectly did not get back to him on the CTAF.

Narrative:
I was beginning a tour of the hoover dam and there is a spot where numerous tour operators converge from different angles to generally follow the same 'south turn' around the hoover dam. The agreed upon altitude is 3;000 ft and there are two rock peaks that mark the convergence point. I was heading toward those two peaks when I suddenly noticed a helicopter to my left at about 500 ft away. He made a call to me to ask if I saw him; but it caught me by surprise and I did not reply. I was focused on making a gentle left turn to give him space to enter the s-turn ahead of me. I did a fairly tight left 360 and fell in behind him. He was very upset over the radio and I incorrectly did not get back to him on the CTAF.
