Revealing mistake: When Higgins shows Magnum the article that (allegedly) manipulates his words to support the thesis that Karen was driven mad by 'Nam, the paper uses the famed recurring filler text that many Earl Hays Press papers use ("An immediate investigation is assured") that appears in dozens of movies. (00:15:50)
Revealing mistake: Magnum confronts on the beach the slimy journalist and he 'threatens' him. He then turns around to leave. Close-up on Reporter Eric Daniels and after a second you can see in the left corner of the screen a tiny bit of Magnum's maroon hawaiian shirt pop in view. He never left. (00:18:50)
Revealing mistake: During the flight towards Karen's location at the end of the episode, TC's chopper suddenly has emergency floats equipped on the skids in the shots when it flies over the coast. (00:43:00)

Revealing mistake: Magnum takes an ancient gun from the cabinet and stumbles upon one of the eccentric millionaire's practical jokes. The joke though is an impossible one; the string that supposedly triggers it is not there, and when the gun goes off, Magnum is not holding the gun in a way that would pull it. (00:16:25)
Revealing mistake: During the gun prank, you can see in the revolver's cylinder the bullets - except when it squirts, the bullets are gone. (00:47:00)

The Arrow That Is Not Aimed - S3-E13

The Arrow That Is Not Aimed - S3-E13
Revealing mistake: Gallagher, the Tourist Shop Owner has been fished by Magnum but, as one of the doc workers says, he's been "Down there long time, bro, pretty bad shape" and he is "in intensive care, unconscious" later in the episode.

Basket Case - S3-E14
Revealing mistake: Magnum's team loses by some extraordinarily bad luck, since the whole laws of physics conspire against him; the ball hits the hoop following a counterclockwise motion without going in, but in the last shot, when it flies away, it is spinning clockwise. (00:45:10)

(00:45:15)
Forty Years from Sand Island - S3-E17

Forty Years from Sand Island - S3-E17
Revealing mistake: Magnum usurped Higgins' desk while he's at the hospital. He is checking out of the article about Enoka running for Senate.

(00:16:35)
Forty Years from Sand Island - S3-E17

Forty Years from Sand Island - S3-E17
Revealing mistake: When Higgins' wheelchair starts taking off and he cries "I say, MAGNUM!" you can see rise from the grass a thin line used to safely halt the chair when off camera. (00:28:05)
