How much did you paid for it? Whats the weight in total?



Oh I just bought mine for $599  ;D (just book a trip in Feb to try out!)


Total weight i don't really know let me calculate.....

Aluminum BP =around 1kg
Harness = 0.5 kg (Est)
Travel exp = 1kg (Est)

Plus 4x D-rings come with the basic harness.I think around 2.7kg ?

the basic harness is usually good enough unless you have super soft skin. if you wear wetsuits, you won't feel the difference too. the deluxe harness would be useful if you have to carry your gear over long distances, like beach dives where you need to carry it from the carpark to the beach. but that's more common overseas where people have their own tanks and weights and no dive guides/DMs.

the deluxe harness adds weight, bulk, and is a little harder to dry. see if that is worth that little bit of comfort for you?

i've cut down my rig to a diverite 44lb wing (i need extra lift for the camera rig, and also if i ever get into a rescue situation with a victim to manage. 18 and 24lbs is too small in my opinion), oxycheq ultralite travel pack (only 272g!), basic harness, D-rings, and my favourite halcyon tank bands. I think it's about 2kg-ish, maybe 2.5 now.

Antacid I just wonder, will I have a sufficient lift above the water on a 27lb bladder?

I really like the concept of the 1 piece basic harness.

From what I gather, the HOGarithan divers might argue that the Basic harness will be much better, one single piece of Harness = less point of failure, and a lot easier to replace if broken (Go Army market to look for a 2inch webbing if you ever need replacement).

My next BC will probably be a using 4m of my old Army 1 3/4" nylon belt, possibly a Zeagle Express Tech Cordura plate/Alu plate and 32lbs - 44lbs wing.

Antacid, do you have a bouyancy calculator of sorts?

Antacid I just wonder, will I have a sufficient lift above the water on a 27lb bladder?

You're 27lbs will be sufficient, no heavy camera rig nor heavy crab catch bag right? ;D

not sure what you mean by a buoyancy calculator? if you are asking about the lift capacity of the BCDs, they are usually found as part of the product specs.

fusion> yes 27lbs is great for recreational diving, no worries there. i kiasu & kiasee only. but for divepros 18lbs is definitely too small. of course, you need to factor in your natural buoyancy (or lack of), wetsuit, and number of weights used.

i had a halcyon pioneer which was 24 or 27lbs of lift - i can't remember. when i dive with my camera and fully inflate the BCD, my chin is just an inch or two above the water. in rough seas i'll get dunked pretty frequently, and if there is a rescue situation i probably would have to dump the camera. then the victim might be wishing i didn't rescue him/her after seeing the bill...  :D

Antacid.. ur pioneer wing is 27lb lift.  :)

Using a buoyancy calculator for most ppl will ended up with 16~20lb lift requirement.  But that only says how much it takes to keep ur head above water.  But in real world, unless u r diving in flat calm waters (no wave).. and ideal conditions (not trying to save/help buddy or something like that).. I think we should add another 50% lift to our requirements.  18lb wing has almost no drag.. but I think its too small (unless u dive in a pond).. 27~32lbs is generally good enuf for most single tank rec divers.. too big a wing will generate too much unnecessary drag underwater... though you will be thankful to have a KS big wing in a >2m swell seas.. Once I was using a 44lb wing and sea was really BIG... I was enjoying the 'ride' while the rest were drinking water..  ;D ;D ;D
So they call it a 'FACT' coz someone made some statements on a 'FACT SHEET'? hummm...

Antacid:
Naa. Was hoping you have some excel spreadsheet that I once saw could calculate how much lift you need taking into account weights, camera rig, wetsuit buoyancy, etc. Thought you had it and knew how to use it :D

I found that my 35lbs bladder was able to: Let me carry my aluminium prawn net with .5kg load on surface, 5kg of crabs in my catch net, camera with strobe. 6.5mm semi-dry, 18lbs of weights, 2 Aluminium dealextreme torches. but never quite figured out if I was weighted correctly, more aga-ration than calculation

people apply rule of thumb for buoyancy estimations as compared to really detailed calcs
e.g. read that it's 5lb diff for full vs empty alum. 80cft tank..that kind of stuff
although i should say a little larger lift provides some flexibility to dive with additional gear, steel tank or 1 small deco bottle

for rescue situations most people should release their ditchable weights first i think..?

on a choppy sea surface people usually recommend using the regulator for short while, hence the value of good gas management to always have spare. getting back to boat should be as quick as possible and not hanging around the surface too long. if for some reason the boat isn't close by then could be a planning problem... :o
