MT500: Omni versus Slimline?

I’m assuming the difference is in the physical dimensions, but can anyone tell me how to spot the difference? I don’t have the two models to compare.

I believe the Omni is thicker than the Slimline. The MT500s used in the film are 1.5" thick at the base and 1.75" thick on the upper half with the speaker. There are also long and short bodied MT500s (referring to the overall height of the radio); the short body is accurate.

Here’s an interesting discussion on the various radios used in GB1:

I hope that helps!

Thanks, man. Appreciate it.

I’ve got an Omni PL (long) from the looks of it.
