Mike Apeks regulators are superb and very reasonable in price (in the UK). >1) Is the Tech-50D the setup that most people go with.?

Or is > the DS4 first stage (non-swivel hose mount and 1 hp port) a > better choice? I use the US4 which is the same as the DS4 but unsealed. The Tech-50D first stage has an O-ring on the swivel and the over size port, as you state, which is why I did not go for these regulators. However, many people use the Tech-50D which is a fine set up. For the second stage I use the TX40 as they have no breathing resistance knob - eliminating another point of unreliability - on the adjuster O-ring. The US4 and TX40 arrangement is very much cheaper than the Tech-50D setup, though I went for this due for simplicity and reliability. The US4 is a standard Apeks product, but may not be available from one of the companies that badge them. I have 6 Apeks regulators and only one failure: a blown diaphragm. They are still performing well but probably due for a service after 2 years of use. > 2) What is the Flathead Six first stage?? I have never seen > this discussed except in the Zeagle catalog. Does anyone > have any experience with this unit? I believe this is their new first stage of which I have no experience but the shape of the first stage is not as neat as the US4, etc. Note that there was a review in Diver Magazine of this setup but the product supplied has a design fault in it which has reportedly been corrected. > 3) I assume that the DS4 first stage is appropriate for stage > bottle use. Yes, I use the same regulators for all functions, thereby allowing inter-changeability. > 4) Any problems with the DIN to Yoke Converter if you have to > go with a yoke connection? I've used converters for DIN to Yoke for recreational stuff without any issues. > I have looked through the archives and various web sites but > would like a little more input from somebody with actual > experience with these regs. > Thanks. Mike I've sent some stuff out before an will see if I can find it and send to you. David Shimell Project Manager, Sequent Computer Systems Ltd., Sandton, South Africa.
