Eccrs are by nature, inspire operator complacency. The problem with the current designs are the hand off nature of those designs. As gill has said independent control needs to implemented. one side does the HUD and a hand set, the other side does the setpoint and a hand set. no mixing of the batteries they should be large enough to handle all of the power loads. no hot swapping of the controllers, the best controller underwater as proved by the kiss system is the human mind. Some of the designs in development out there are two cell only, for each side. that allows for complete Independence of the controllers. but you say how does that allow for three cell voting. it does not. but it allows for the operator to be informed that a cell has failed when either hand set displays a problem. those design force the operator to initiate a dil flush to determine what is going on with the cells. even with three cell voting you should be forced to initiate a dil flush to determine what is going on with the cells, on a single cell failure. because we do not know i we have two cells water blocked and only one cell reading right.


the basic thought behind the three cell system is that if a single cell fails we will be able to determine what cell has failed. but this does not take into account environmental conditions ,IE. condensation that could take out two cells at the same time. so we have to add in injection failure software in case the cells don't see the o2 injection. and the design thought that blowing dil on the cell faces to clear them is even worse because it just hides a design flaw that allows for the cells to become water blocked and will not allow for proper diagnosis of the problem.

As we look at the current systems out there, ask yourself, do you trust them?

controllers are just like a regulator if it fails you are done with it this dive.

we as consumers demand that the next piece of equipment has more bells and whistles then the previous piece. this is stupid. do we really need a car that can parallel park itself? no. instead of demanding that the manufactures spend money developing deco controllers, and by the way the are not doing doppler studies with them. they are just using somebodies else algorithms and hoping they got them right. we should demand that they spend this development money to ensure that the units currently out there are right, and will work every time. while it might be fun to drive to work in a lotus,. a chevy will get you there, and will get you there more often.

gill you said that you where disappointed that the inspro would not allow you dive the with a broken solenoid. my question is why would you want to risk your wifes life with a piece of broken equipment to save a dive. you would let her enter the water with a free flowing regulator, no. so why would you allow her to dive with a broken controller. by the way if you could convice my ex to dive with you go for it. as long as i am out of the country.
