As per my knowledge the freedive fins helps you gain more grip underwater which you will obviously need given the time limit you have vs Scuba divers.
For more knowledge on freedive check this thread out, its a good starting point!

Hello and welcome on DB
long fins will give you more speed underwater which is very important since there is time limit in freediving. Low volume mask which is used in freediving is important specially when you go deep because you need to equalize the mask by pushing air from your nose inside the mask if it is big you will need more air which will reduce the amount of air in your lungs.
All best

Re. freediving masks v. SCUBA masks
Freediving masks tend to be twin lens to reduce internal air volumes to the absolute minimum practical. This is because freedivers have only one breath to do everything (equalize ears, uncompress mask, oxygenate brain & muscles, etc.), while SCUBA divers have a tankful or two. Low volume masks have less air to compress and require less to uncompress (if necessary) at depth.
Freedivers also tend to be more more concerned about being streamlined/hydrodynamic because they need to get where they are going without wasting their precious single breath. Spearos especially, usually aim to minimize snag hazards - such as protruding equipment.
For spearing, black or camo (green/blue/brown) skirts on the mask seem far more common that clear skirts. This can cause a significant loss in peripheral vision - not a good thing for a hunter you'd think (especially if in sharky waters). However, I can think of a few reasons for the opaque skirts: (1) it reduces eye strain in sunny conditions (less direct sunlight entering eye, especially from above), (2) an opaque skirt will tend to cover highly visible pale face skin and can be chosen to match the spearo's wetsuit colour, (3) it makes it harder for fish to detect your eyes and determine what you are doing - I suspect the latter is the main reason. Perhaps it is partly tradition too. One obvious way to solve #1 would be make the skirt opaque above the eyes and clear to the side and below - tricky to manufacture but somebody will probably do this one day. Mirror'd lenses reduce issue #2 but reduce available light, so only suitable for sunny climes/clear water.
SCUBA vs. Freediving Fins
Two main differences come to mind: Freediving fins tend to be full pocket and shaped long and slim. I suspect that is partly because freediving & spearing began as recreational snorkelling, where folks just put on minimal gear with their swimming costumes -- full foot pockets are often worn without boots or socks. Also, if snagged (on a breath hold), you could probably slip your foot out more easily. SCUBA fins usually seem heavier, perhaps to stand up to the rigours of heavily equipped SCUBA divers and the rear entry foot-pockets allow for fine adjustment with a wide range of clothing (e.g. drysuit & thermals) and boots (booties, winter boots, neoprene socks). Not sure why SCUBA fins tend to be short & wide and free diving fins longer & slimmer -- perhaps somebody else can provide insight on that? Perhaps something to do with freedivers being more performance oriented (e.g. more hydro-dynamic) and SCUBA divers having to deal with enough awkward equipment issues without having super-long fins? I like the full pocket spearing fins but could see a benefit to being able to wear booties suitable for rock-hopping and pebbly beaches (like the new Sporasub clip-in fins perhaps?).
