First off, two facts:
- Tom is one of my Dive Buddies
- I own a Ranger BC
I have found the Ranger to be a very capable BC both as I have been gaining experience diving recreationally (carded in Dec 200, and 45 dives) and as I gain experience and increased interest in the world of tech diving. The Ranger was recommended to me by a diving friend who has been tech diving for over 10 years, and who dives often on wrecks and is also full cave certified. When Marc and I discussed BC's, I had expressed an interest in wreck diving and eventually working my way (slowly) through cavern and basic cave. Marc had recommended the Ranger because
- He knew that I needed a capable BC that will handle both recreational and moderate technical dive profiles
- all components are modular, which results in about as custom fit a BC as you can get
- it will allow you to change out the bladder for increased lift that is often required for tech diving (remember, when doing tech, you're often schlepping lots of heavy gear around through the water)
- it will allow fittings for double tanks
- there are tons of attachment points for gear
- lifetime warranty
As my first BC that I have owned (and compared to the 4 other vest BC's that I had rented) I can very enthusiastically recommend the Ranger for someone who is looking to eventually get into tech diving and do all the recreational diving you can.
Now with all that being said, let me confuse you even more

. I also agree with Tom that you should take a long look at the Backplate and Wings style BC, such as the Dive Rite Transpac (and the others). The reason I say that is take all the reasons I like the Ranger, and then add in its increased versatility.
BP/Wings BC's can be (by design) setup for each particular dive profile that you are attempting. In other words, these BC's can be torn down, and then reassembled with the correct configuration to meet the current dive's requirements. They are very capable at handling recreational dives, and are designed for the aggressive technical dives. As my buddy Marc told me, "Each piece of dive equipment is a tool. You choose the best tools for the job and the dive." Marc owns both a Ranger and an OMS BP/Wings BC's. When he is diving recreationally, he will jump in with the Ranger and a single tank. When he is diving on wrecks, technical diving, or doing deep diving with intentional deco stops, he will use the BP/Wings.
Now you're probably thinking, "Hold on, up there you said you're all for the Ranger. What's this praise for the BP/Wings?" And it's a good question.
Now that I have much more experience (Both in the water, and out by learning from this board and my intructors), I will probably upgrade to the BP/Wings BC's. But most likely only after I enter into dive profiles that exceed the Ranger's capabilities. And that's a ways down there.
One of your criteria is not to have to replace the BC you choose quickly. If you see yourself moving into tech diving within the next 3 years (in otherwords, like me, you're going to get all the instruction and dive trips setup that you can afford), then make the BP/Wings choice #1, and the Ranger Choice #2.
But if you are going to hold off on Tech for a while, then go with the Ranger first since it will do you proud for all the recreational diving you will be doing, and still handle much of your technical training.
Thus ends my take on your question. I hope it has informed you some and provided some things to consider. If you have more questions, please post them. That's what we are here for.
