Going deeper than 100ft?

[Mullins]

1m/s ascent speed is fine, the problem with VWT dives is that you tend to rocket up in the last 10m or so. It's possible to do 2m/s quite easily if you get carried away and keep kicking. This isn't too bad for a couple of dives but if you're doing several to, say, 40-50m the fast ascents increase the risk of DCS. Not that anybody knows exactly what depths/repetitions/ascent speeds would put you at high risk; rather it's just a general caution.

Thanks Dave! We mess around with a vwt a little but it's a hassel to pull it up. We will do 35 m at the most. It's a fun ride down and we get great bottom time but it's hard to say how battling a big fish would be at that depth. So far we've only shot small fish.

Thanks

i'd also add a note of caution with the variable wright dives, this isnt amature stuff, the descent speed can get away from you if you arent careful. and also keep in kind the longer distance back to the surface. it certainly works just make sure your safety is up to scratch... Dave not directed at you mate! your constant weight dives are double my VWT dives! hahahahaha

just general caution thats all spearing on NWT brings new risks!

Thanks DivingDane, your point is taken. We are no where near the caliber of you guys. We are just happy to get your advice.

I'm weighted to be neutral at 10m so I might just use the same weight belt and a 8 or 10 pound VWT? I would be screaming to the bottom and the trip up would be easy.

Thanks

hahahah i'm no expert! i'll leave that to mullins and Efattah!!!!

bouyancy is fine just make sure that you arent screaming to the bottom too fast. you may not be able to EQ quick enough and then you start going into bustes ear drum territory! not fun.

just take it slowly using light weight to start and add a bit as you become more comfortable, start doing VWT dives to depths you can comfortably dive anyway and then work from there.

good luck with it! ande have fun!

I signed up for a PFI class after making this thread. Hopefully that will increase my knowledge of freediving a bit before I attempt the deeper spearfishing

get ready for a revalation! good choice.
