    Good point. The DX uses the same.

    Actually (according to Suunto) they do use the same base RGBM as the other Suunto's but they also have the Tech RGBM algorithm, which it's supposed take over at around 30m. Again according to Suunto it should behave in a similar fashion to the rest of the range at shallower depths.

    What I think makes the difference is the conservatism settings, I get the feeling that the "fudge factor" offset is different across the range (steps of conservatism)

    If I dive mine at +1 (one step of conservatism above default) then it seems to be similar to other Suuntos default and certainly the Cosmiq Deep blue default (I've dived repetitive dives with a buddy on the deep blue)

    I suspect that most manufacturers apply different offsets the the algorithm across their range. Therefore an entry level computer designed for newer or infrequent divers maybe made to be more conservative than one further up the range despite them using the same algorithm. But I could be wrong

    How long did your dives usually last for? For my weekly diving I need to stay at 50-100 feet for an hour tops. I never came uncomfortably close to my NDL using a sherwood amphos (dsat). Would the pz+ make a big difference in these situations?

    Thanks!

    Good to see someone so close on the forums! I dive Bandar Khairan and Fahal Mainly. Dimaniyat is more of a treat!

    The AL computers haven't been around for too long so perhaps thats why they're not as popular. AL Boom is the regional AL dealer so I suspect they will have good AL support (I'm counting on it and Dubai diving to provide service). The eon steel is a good computer however I'm finding the AL for half the price at the moment.

    At around 50', my dive time was just barely over an hour, but that is including all ascent and descent time. Probably 50 - 55 minutes on the bottom. Around 75 feet, total dive time was more like 45 minutes. So, 35 - 40 minutes on the bottom.

    Al Boom will provide good support, I was divign with the head of their technical dept at the weekend. They have had some back, with some minor issues, also some users have complained about battery life with the screen turned up to high to read it here. There have been some bugs, but also some firmware updates, hes' not sure if these updates have fixed some issues. He doesn't dive one himself.

    As for being new, yes you're right, but I work with a lot of the operators here so tend to see what equipment people are wearing. I've seen 1. I've seen more deep blue cosmic and perdix than the AL computer. But if its the right computer at the right price for you, go for it.

    If you don't mind the relatively short NDL times of PZ+, you will be fine.
