Hello guys.
I´ve been using a Us Divers Sea4 regulator for almost 15 years. I usually dive once a year in a warmer liveaboard vacation.
The last service was about two years ago and i have no problems in finding the repair kit.
I used to have no problems with air consuming. But in the last two trips I have notice that my air is going away faster than the average. I really don´t know if its a problem with me or a problem with the regulator.
I read in other posts that SEA4 it´s a solid first stage (and it´s a heavy one too). But it seems that if it can keep the "working" pressure for the second stage, the only problem in decision to keep diving with this regulator it is the weight that it represents in the luggage.
In the same way, a brand new good balance second-stage will decrease my breathing effort for about 1 joule/litre (It´s seems that the old Sea4 require more than 2 joules/litre.). Is it true ?
So, the questions :
Quality of regulators sets determins hardly the air consumption at recreational deeps ?
These numbers 2 or 1 joule/litre are big diference numbers ? Of couse it´s 100%, but it means anything in the end of the day (or in the end of tank ?).
In "recreational" deeps which is more important for breath performance : second or first stage ?
For recreational diving, if I connect a good second-stage (like Scubapro G255) in the old SEA4 Fist Stage It will have the same effect in comparassion with buying a brand new MK11/G255 set ?
