Continuity mistake: In the barroom brawl, Rick foolishly attacks the huge dude. He backhands him into oblivion, sending him falling back-first off frame. Rick crashes on the stools belly-first though, and the stools were at very short distance, not exactly room for him to turn another time and fall as shown. (00:22:55)
Continuity mistake: Magnum stares wide eyed at Buck and his target practice in the bathtub. In the shot of the room, you can see in the head area of the target already a soot mark where the extra hole will open later - and there is no trace of it in the opening close-up. (00:14:55)
Audio problem: Mrs Joan Gibson, shoes in hand, is waiting for Magnum after his surfski session. He tells her "I'll be honest with ya" and there's a cut. The audio quality in this second part of the conversation takes a dive for the first seconds before finally adjusting. (00:12:25)
Continuity mistake: Higgins and Agatha fall down in the longshot facing the same direction, but when Mad Buck sits up and puffs, they are facing each other instead. (00:07:30)
Revealing mistake: Mad Buck lands on Higgins' beach croquet course, and right on him and Agatha. The two are replaced by obvious stunt people, though. Higgins' definitely has more hair than John Hillerman, and the woman is younger than silver fox Gillian Dobb. (00:07:20)
Audio problem: Higgins interrupts Magnum when he's about to go paddle in the ocean. John Hillerman's voice is dubbed over, and it's easy to tell because the background noises almost disappear during his line, to resurface when he's done. (00:02:15)

Character mistake: At the station after the release of the first suspect, Kelly does the good cop routine and apologizes for his Sergeant, saying he does not like a private eye telling him how to do his job. Magnum 99% of the time during the show corrects people saying "private eye" with "private investigator", but here, he does not. (00:16:20)
Wave Goodbye - S2-E7
Plot hole: For two patrol officers (one of them being kinda green) in Honolulu, Kelly and Jordan sure seem to have the weight of the entire State on their shoulders; they also investigate extensively the murder case, and they, until a month before, "worked drugs in that area", which was a piece of jungle around Maui. It's like the department for this episode and this episode only has no detectives, and a couple of random beat cops are covering the archipelago with highly specialized duties.

Other mistake: When the bad guy pulls the gun on Magnum, the last twist is spoiled a minute too early if you notice the shadow of the actor on the right side, already standing by just out of frame. (00:46:40)
Wave Goodbye - S2-E7
Revealing mistake: Magnum finds the trap the veteran put in the plantation. When he walks past it, the camera pans to the left following him, and hits and moves a branch with a very noticeable and unmistakeable effect, not simply the rustling of the wind. (00:25:45)
Wave Goodbye - S2-E7
Visible crew/equipment: When Magnum opens the door of the beach shack, he does not seen anyone, but in the glass there's the reflection of someone standing, their silhouette clear behind the rack of set lights. (00:12:30)
Wave Goodbye - S2-E7
Character mistake: At the end of the episode, the cop reads the culprit his right, twists his arm and exits stage left with him. But 'left' happens to be towards the ocean, away from the patrol car. He also leaves the gun behind, lying in the sand. Worst cop ever. (00:47:45)
Wave Goodbye - S2-E7
Visible crew/equipment: After the drug runners' target practice, Magnum and his friends are assessing the damage to the chopper. During the scene, in particular when Rick tells him "You don't have a client!", the chopper's glasses reflect crewmembers. (00:35:00)
Wave Goodbye - S2-E7
Visible crew/equipment: The Sarge and the rookie cop leave the bar, and Magnum, scorned, gets on the car to leave as well. In the left side mirror, clear as day, the reflection of a crew member's face. (00:32:15)
Wave Goodbye - S2-E7
Audio problem: Magnum is talking with Nick, the traumatized Vietnam vet. When he says "Maybe I've seen the kill. Maybe...I've just", his lips don't move for the last words. (00:29:05)
Wave Goodbye - S2-E7
Continuity mistake: TC elbows Rick protesting for the choice of cover-up name. Between them, the big boned waitress smiles and turns around with her tray. The bartender is on the phone with the dealer, and it cuts briefly to the duo waiting at the counter. The waitress is still there, turning and smiling. (00:20:10)
Wave Goodbye - S2-E7
Continuity mistake: During the scene at the Kamehameha Club when Magnum enlists Rick and TC's help, the same woman with a navy and white swimsuit with a white belt walks by the surf first, then behind Rick, with a different guy each time in the span of a few seconds. (00:17:10 - 00:18:00)
Wave Goodbye - S2-E7
Continuity mistake: Gary Something enters his own home on the beach and Magnum is on all fours with the two cops pointing the guns. The older one is holding the gun with just his right hand, but he is handling it with both in the next shot. (00:13:50)
Wave Goodbye - S2-E7
Continuity mistake: Magnum is being searched by the young, nicer cop in the shack. His colleague is holding his gun with his arm loose, but he's got the thumb on the holster in the next shot. (00:13:05)
Wave Goodbye - S2-E7
Continuity mistake: In the scene with Magnum approaching the two cops on the murder scene, the light difference between Selleck's close-ups (casting a marked shadow on his chest) and the rest, is quite striking. (00:08:30)
