Hi Sharon,

forgive me if I bounce around all over the place in my thoughts, I am sure some of the other board members will are more learned than me will contribute.

If you do decide to go doen the SCR route you have a few options.

Drager Ray

Nice small unit (we have one down Wraysbury lake - if you come down I will get you a try dive on it and on the Meg too if you like) - to be honest probably not the best choice as you can not change the jets and off the top of my head max depth is about 20 metres. Price abotu £750 second hand and about £1500 new if I recall correctly.

Drager Dolphin

Lovely unit, ultra simple I have about 35 hours on it or so and am a fan. Expect to pay about £1000 to £1500 second hand about £2500 new and on top of that any where from £400 to £1000 to either monitor the PPo2 or get an integrated deco computer. typical BSAC configuration is to use a 10l cylinder with a H valve which will give you plenty of bailout in a self contained unit. Also can be converted to closed circuit.

Your other option which is brand new on the market is

Submatix 100ST

This unit is about £2600 see http://www.abyssuk.com/products/prod...bcatcode=SMSCR afraid I dont know a lot about this but you can change mixes during the dive.

Azimuth

Afraid I again dont really know a lot about this one. Other than you can change mixes between 2 cylinders during the dive and again its about £2500 +

Others

Other units such as EDO or RB80 - have a look in our articles section for a review. These units probably not for you as are designed to work at depth with trimix etc.

Other Options

Sport Kiss

You can pick one of these up for the same price (maybe cheaper) than a new SCR! PM decoweenie who is the best bet for you with these (Phi drop Sharon a PM)

They have numerous advantages IMHO, they are Kisses recreational CCR and are certed to 45ish metres althouh have gone a lot deeper (about 100ish isnt it Phi?).

They also dont have a bunch of electronics or a solenoid and work via a constant mass flow valve to inject O2 at a rate similiar to you metabolising it, with a manual add valve for your tweaks (monitored via built in PPO2 monitors).

With a CCR you will never have to worry about your dive plans being changed and so your mix and jets being wrong, they are also very simple and are a manual CCR with electronics included in the price to monitor your PPO2. There is a review here and information on diving it here.

With this unit you will really be maxing your PPo2 on every section of your dive not just your deepest part, you will stay out of deco longer and when in deco your deco will be shorter. The unit will also last for a weekends diving with out being touched!

Training

Go for some one that actually dives the unit that you buy and has a lot of hours on it diving the type of profiles you want to dive....I would say thats more important than whether they are BSAC or another agency...

PS Apologies to those SCR fans I have offended - these are just my opinions and I am a nerd!
