Well since folks are discussing the difference between the GB1 and GB2 packs, I thought now would be a good time to post a bunch of reference pics I captured from the film. They’re mostly uniform shots, but there’s some pack stuff in there as well, like the positioning of the padding on the back, the color of the LED hats, and which switch on the wand does what:
Nice observations. I watched GB1 for the first time after constructing my pack and noticed how little it actually shows the packs and equipment.
If you look at the ecto goggles in the last pic you might notice those have some differences from the hero goggles also. See the yellow hose coming out of the battery compartment, and the cylinder thing on the right?
Also, is it just me, or is that gun ear the red wire connects to on Ray’s wand rather long? Or maybe not long, but narrow?
Maybe that’s normal though and I’m just remembering the plans wrong, or the resin part I got was made thicker for strength. I’ll have to check later.
That’s actually a plastic strap that is originally on the battery cap to help prevent it from getting lost. Most older frames have this part broken or gone because the plastic is brittle. If I remember correctly most of the end shots were filmed first, though there would have been a few sets of goggles made more than likely.
Something I noticed while watching the movie, but I’m not sure it’s been mentioned. Probably has, tho!
See the motherboard edge padding in this pic:
Highlighted it here, but it’s pretty obvious, really:
Looks like it might be that dense, closed-cell foam (like camping sleep mats). Think it’s only seen in the Gozer showdown scene, tho. Probably 'cos the guys had to keep looking up!

thankyou GhostGuy for those screen caps. noticed one or two things i got to change on my pack now 
Watch this again, immediately before this scene they show their backs and the pack is already on…
Just like the elevator scene, no consistency or continuity, just dramatic movie magic…
Well now you’re nitpicking.
Yes, you’re correct… You see the lights on when their backs are to you. However, I forgot to tell you something very important. Don’t cross the stre…
Er…
Before they flip the switch… the bargraph is already going and the white light next to the clippard valve is on.
Also, the fact that the cycltron lights and the bargraph are on before they flip the switch doesn’t change the fact that the pack powerup sound plays when they flip it. It plays when Egon flips it as he leaves the elevator… It plays when Louis does so at the end of the second movie.
And as this is the only time that they show the switch being flipped in a closeup, and the sound playing, I think it can be considered canon that the bottom switch is the one that plays the pack powerup sound… unless you plan on installing an imaginary switch in the side of your pack to do the same.
I also wanted to mention that the padding, in the second movie, on Louis’s pack at least, does go around the bar on the alice frame. So that would be yet another difference between the two versions.
He never flips any switch in that scene, and no lights are on or come on… He simply “jerks” the gun and the sound plays…
Also when Ray is about to blast Slimer, again there are no lights on in the gun, not even the front tophat, he flips a switch and the tophat light still isn’t on, vent lights and pack power up…
As I said no consistency in the effect… That is why when I did my kits, I allowed for customization of switches and tried to lay them out in a fashion that Christphern and I figured would be more realistic to what it would be like in real life…
IMO there is no right or wrong, yes they overlaid the startup effect in that one scene when he flipped the bottom switch but it was also overlaid at other times, pretty much just a roll of the dice…
My 2 pence worth…
The light inside the gun is off until the switch is flipped os per ghostguys explaination. He is right. I just watched that scene again to make sure. The ‘heat em up’ means light the inner switch.
What scene are you talking about? Yeah the vent lights and power up sound come on with the bottom switch in the close up scene, but this effect isn’t consistent throughout the movie, and as I said it’s kind of silly the pack power up sound played as the pack was already on as could be evidenced by the powercell and cyclotron clearly already on immediately before that…
That particular scene as in the photo. The bottom switch is flipped and the vent light comes on. The barograph is already on and moving. However, no matter the inconsistansies, in that screen shot ghost guy is correct.
Heh, how did I know you were going to call me on that one? Yes, he just shakes the gun, but the point was he does something with the gun to turn the pack on. 99% of the time, the ghostbusters turn the pack on from the gun. The elevator scene is a fluke. That’s all I was sayin’.
Yes, but that wasn’t a closeup!
Would you have us believe the “real” packs were made of foam or rubber simply because they used those in some long distance shots?
I don’t remember how your kit works since I haven’t finished my pack yet and have only powered it up once or twice, so I can’t really comment on that.
Of course you can lay your switches out however you want. Maybe you want the switches to do things which are consistent with the labels. Or maybe you want to be consistent with what they actually do in closeups. It’s your choice. I was just pointing out what he did in that one scene, and what the result was. There’s really no room for debate there.
Concievably, “Heat em up!” could mean spin up the cyclotron. We know the lights move slowly in some scenes and fast in others. So the cyclotron could merely be in a standby state as they walk up the steps.
In fact, if you look at Egon’s pack after they fire at Gozer…
The pack lights and power cell are moving very fast.
Speaking of which, I timed this frame by frame and tried to set your kit up to go that speed, and it just barely reaches it. The limiting factor was the power cell speed. The cyclotron on your kit could be made to go faster than seen here, but then you wouldn’t get the (approximately) one power cell fill per cylo light switch seen here.
Oh, and speaking of realism, there’s one light kit that is available actually makes the lights “spin up” as you hold down the fire button, and then spin back down again. That’s a pretty cool effect… though not +$200 worth of cool.
You’re welcome!
Speaking of stuff on the pack that’s been missed though, what’s this?
88 MILES PER HOUR!
hahaha i dont know whats making me laugh more, the flux capacitor or Dan’s face
That flux is not accurate at all.
Wrong type of lights, wrong colours…
Back on topic of the light/switch…
I looked at tons of videos online (happy youtube) as well as Exoray’s and movies… ended up making my own. The movies isn’t specific ennough, and everyone is different.
I don’t think there’s a “wrong” way of doing it, so as long as it makes sense to you…
I agree, Marsupial.
The pack fire up sounds were never triggered by any switch.. they were added in post production, so everything we see is open to someone’s interpretation.
Knowing people who’s worked on movies and props, sometimes things work, and sometimes they don;t. Since film producers aren’t arm chair quarterbacking, they don’t sweat the small stuff, or worry if a light works or not, unless it’s something truly important. If something doesn’t work, it can always be doctored up in post, be it a visual effect like a light, or a sound effect like powering up.
I’d say the more advanced packs done by fans are probably 10 times better then the originals, as far as features and durability.
