I200c or i300c?

Does all oceanic computer allow u change the algorithm on the fly? Or they sell different model with different algorithm

All current Oceanic computers are dual algorithm Innovation » Computers There are four choices for level of conservatism. From most liberal to most conservative, DSAT, PZ+, DSAT with conservative factor, PZ+ with conservative factor. The algorithm, with or without the conservative factor, must be chosen before the dive. Once chosen, the algorithm settings are locked in for 24 hours after the dive. This is from my Geo 2 manual:

To give you an idea, here are the NDLs for a 1st, clean dive to 60 feet on air:
DSAT 57 minutes
PZ+ 48 minutes
DSAT with conservative factor 43 minutes
PZ+ with conservative factor 37 minutes
There are complete imperial and metric tables in the back of the Oceanic user manuals, available online Support » Manuals

Should note that Sherwood computers are also Pelagic using DSAT.

Yes, so is Genesis. Only Oceanic is dual algorithm

And Aeris if you find it. Speaking of: Anyone want a good price on an A100 2 gauge console? Still new, never used.

Is there only one conservatism setting per algorithm or are there several of them?

@BurhanMuntasser, there is only one conservative factor per algorithm, at least in the lower end Oceanics. Much like what is available in the Aqua Lung i300.

@RIHappyDiver is correct, there is just one conservative setting for DSAT and one for PZ+, for a total of 4 settings. The conservative factor is very simple, it is just moving the altitude to the next higher group. For example, sea level is 0-3000 feet, the next higher group is 3001-4000 feet.

You are saying that their adjustment of conservatism is merely changing the altitude to a higher altitude or is the altitude adjustment in addition to the conservatism adjustment they have? I know that my Suunto computers had 3 conservatism adjustments but also 3 altitude adjustments that can be used as additional conservatism adjustments for a total of 6 adjustments.

They shift the calculations by one altitude "bracket". Altitude remains a separate function. I haven't checked a broad range of specific items, but I think the altitude adjustment is automatic on more recent models of most manufacturers, rather than a manual setting. Progress...

Yes, the conservative factor is the next higher altitude group
