Sending someone straight in to tech style gear may not be the best idea. While I do understand that doing some tech diving may be an end goal you really should step back and ask yourself how much experience and diving are you looking to do before you start to pursue tech diving?
Firstly.... BP/W is not 'tech'. Nor is it exclusive to 'tech'.
It is a buoyancy control device, plain and simple.
Technical divers use a BP/W as the basis for mounting twinsets and carrying multiple stages.
Recreational divers use a BP/W with a single cylinder...adding and subtracting air from the bladder using an LPI to attain neutral bouyancy during their dive. The same as any jacket style BCD.
Regardless of any benefits brought by future upgrades of the modular system to cater for technical diving activities, there is also a strong logic behind choosing a BP/W configured for single tank, recreational diving... based on the inherent advantages of the BP/W design alone.
Secondly, my dive center exclusively uses BP/W from OW level upwards. I can teach open water students in them with no problems at all. We put fun divers into them as rental gear. There is no issue with doing this...and the feedback I get from experienced divers using them for the first time is overwhelmingly positive.
I ask this because your estimated budget may not allow you to get in to a BP&W setup right from the start. The entry level equipment you picked out will defiantly be safe and allow you to get more dives "under your belt" while you develop your skills.
There is maybe $100 difference between a basic BP/W set-up and an entry-level bcd. If you buy second-hand or Ebay (
especially items like backplate and DIY harness set) then a BP/W can easily come in cheaper than a jacket bcd. I will soon be selling BP/W here at $330.
For the sake of $100...you will be gaining a set-up that will last longer (more rugged), easier to maintain (modular system) and will evolve to match your needs as you progress in your diving. Buy a cheap jacket BCD and you'll probably be Ebaying it in 50 dives time at a substantial loss.....
There is nothing wrong with the gear you've selected per say and there is nothing wrong with the BP&W setups people recommend. You have to determine for yourself what your upgrade path is. If you're going to do 50 dives in 5 months time and go in to tech diving then you may be best to save some more money and buy a BP&W now. On the other hand, if you think it more reasonable to get 50 dives over two years (that is one - two tank - trip per month) you may be better off starting off on the lower end and upgrading as you go along.
Agreed... there's is nothing 'wrong' with any equipment choice you may choose....and you are bound to like it and enjoy it (if you don't know any difference).
However, it may be 'optimum' to invest in a set-up that will provide a much better long-term investment and is arguably far better performing in the water....
