Sounds good. It'd be hard to go too far wrong with
Omer gear (must get some myself).
Gloves are definitely a good idea for loading & general warmth protection. I think 2mm or 3mm is prob. normal. Len Jones' book suggests gardening gloves but neoprene esp. in cooler climes is prob. the way to go.
You'll need a
float line (see your Norcal picture) although it doesn't have to be that fancy. Then you need to figure out what to attach it to (e.g. your gun's handle, your spearline, your weight belt, an anchor/weight,...). A winder is handy for transporting the line -- although the jury is still out on whether you dive with the
winder or not. Some folk carry a
whistle/compass/waterbottle/cellphone/carkeys on the float, I think somebody even mentioned
mini-flares. Some use a reel on their spreargun.
A fish
stringer, for holding your catch (or
catch bag). The stringer's spike can also be used to dispatch fish ...rather than using your knife (which is also carried for safety). I wouldn't go overboard on the
knife, they are easily lost. Flat knives are unobtrusive & tend to snag less. Dagger blades are better for quick, clean dispatching (although any knife will do the job ... kitchen knives, steak knives,...). I think a serrated edge is a very good idea too -- it cuts more effectively & quickly.
Marseille buckles seem popular on rubber
belts for Spearos, not sure why that buckle design but rubber belts stay in place better. I guess the other buckles are fine too. Any
weights will do, but D-weights are favoured most it seems, then bullet weights - they fit close, offer less drag & do not shorten the belt. Some find a
weight vest/gilet (possibly camo) handy if they have back problems or find they need to redistribute some of their weights.
A more experienced member suggested a
dive computer (Sunnto D3) ...I don't feel ready for that yet though.
If you travel, maybe a
speargun bag or hard case. I made a rather nice neat bag from a £1 tarp, some bubble wrap, webbing tape & bungee cord. There are detailed instructions on making a hard case from plastic drain pipe on the web. Rod bags, gun bags & even cardboard can also be used. Rob Allen offer some with pretty jazzy ones with neat graphics.
At some point a
torch might be useful. See the torch thread for a very full discussion. I like the USA made UK mini Q40 mask mounted torch...but you might prefer a more powerful handtorch. I guess it could also be used for emergency signalling, heaven forbid.
The Len Jones excellent booklet at around $5 or Terry Maas
book for $$$ are probably good investments. Ian Rodger's Freediving book, which he is selling discounted on this forum is good value at around £5 inc. UK shipping -- as it mainly concerns spearfishing. Maybe the freediving manual if you want to pursue that aspect.
DVDs seem a popular way to learn, although they can be surprisingly expensive (perhaps due to the relatively small, specialist audience).
Then you can get a dive
kayak, a
RIB, a
C-Ski 440, a Tuna boat, ...
GPS, fishfinder, VHF radio,....Tickets to exotic places. You don't need that much to get started but what you can spend on it is without limit
.
