Human Factors
I was operating Aircraft X out of ZZZ doing tour flights. I was flying southwest down ZZZ when I heard another helicopter radio that he was southwest; inbound for landing; and Tower told him to report 3 miles to the south and advised that I; the other helicopter; was flying down ZZZ. I started looking visually out the window outside the helicopter looking for the other traffic. I couldn't find them so I started looking on the ADS-B for their location and they were also not reporting with ADS-B Out. I looked out again trying to find the aircraft; and at the last second spotted him right in front of me banking hard right so we wouldn't collide midair. Upon landing I went and talked to the pilot to make sure he was okay and when I told him I was trying to find him on the GPS he told me that since he was from Canada; his helicopter was not equipped with ADS-B. His tail number started with C" not 'N' so I'm assuming it was not an American-registered helicopter. After telling me his aircraft was not equipped with ADS-B Out; he laughed about it; telling me to stay quiet about it as he walked off."
