Is this real? Just add depth sensor and we'll have a next gen dive computer with 3rd party apps lol :). Iphone 7 has reportedly survived a 35 FSW dip.

Check out this link i750T - Aqua Lung Australia - Scuba Diving Equipment Anyone with more info about the Aqualung i750T? It looks interesting. User replaceable battery, OLED, compact profile, Bluetooth 4.0, 3 gas wireless air integration... But there is no mention of Deco Algorithm used.

Is this correct ? METRIC turn pressure = start pressure - (bottom volume ÷ cylinder capacity) It doesn't seem right. The lower your sac rate, the higher the turn pressure. Example: Start pressure = 200 bar Depth = 30 meters B Time = 10 minutes RMV = 25 liters/min ATA = 4 Bottom vol...

How do you increase the number of posts shown per page? The current number of posts per page makes it difficult to read for mobile users. Is there a setting in preferences?

I'm plotting a series of dives to show a friend the oxygen exposure impact of back-to-back dives on Nitrox. Simple sample dives are a series of 10 repetitive dives to 18 meters for 56 minutes on EAN32 with only 1.5 hours SIT in between dives. Purpose is to see the effects of CNS% and OTUs...

Situation is doubles AL80s on Wetsuit. Head heavy. Particularly with two deco bottles on the left side. While using a V-Weight (tail weight) on the lower band is the standard practice, can a weight belt be as effective? Do you use weight belt instead of v-weights to help counter head heaviness...

I typically dive 45 meters for 30 minutes on Air and 50% for deco starting at 21 meters. On VPM or ZHL16c, my first stop would be within 24 meters or 21 meters depending on conservatism/GF setting. In actual Deco dives, my Suunto D9 would show a ceiling of 7 meters after 30 min at 45 meters...

Hi, Using MultiDeco IOS app on an iPhone, I'm trying to do a deco dive plan. 45 meters, 30 minutes, Air + 50% + 100%. Last stop 6 meters. The calculated plan will not include 100% O2 at 6 meters deco stop. Yes, 100% is included in the Deco Mix along with 50%. Is this a bug? What should I do...

Hi all, I'm new to the Petrel 2 and have read all available documentation on configuring and using the unit. Both user interface (OC Tec and OC Rec) are great but the OC Rec seems to have a better layout and data presentation. It also appears, that while the main screen of the OC Rec is limited...

Can anyone shed some light on the differences between these PADI specialties: - Digital Underwater Photography - Underwater Photography - Underwater Videography Everyone is using Digital nowadays. Also, Cameras are both Still and Video capable like the GoPro. So, is the Digital Underwater...

This OTSC dive computer looks smaller (width wise) than a Petrel, replaceable battery, well laid out info, and seems to have all of the functions and features of a Petrel sans the bulk. heinrichsweikamp Has anyone used this OTSC computer? Is it as good as advertised?

Andy, you bring up some very enlightening points. Really appreciate your inputs. Don't stop ;). Question, what GF setting do you use for your tech dives? On your typical 50m Tec dive, what do you use for your back gas and deco gas? This thread was spun off from another thread...

So I calibrated the Petrel compass, declination set to zero. After a few minutes, reading is off. So, calibrated again. Reading is ok. After a few min, reading is off again. Has anyone encountered this? - Compared it with reading from a Suunto sk8 mechanical compass. Suunto worn on left wrist...

Hi Shearwater, Dives with a Petrel 2 (v29) were conducted in imperial units. Post dive, I needed to share my log data with others who needed it in metric units. I Changed "units" to metric on the system setup. However, the data on the dive log (depth, temperatures) stayed at imperial units...

Out of the current line of O2 analyzers across different manufacturers, what is a good one to buy? Need a portable, easy to use analyzer. Would you guys recommend the one that DGX sells?

I currently use 6 lbs weight on an AL80 singles DIR rig. Current singles rig is: Halcyon Infinity AL Backplate BCD, it came with a STA and metal camband buckles, Apeks XTX200 on a long hose, bungeed backup second stag, DIN Apeks FSR first stage with a yoke adapter. Wetsuit 3mm. OMS fins...

What is the Apeks counterpart of the SP560/MK21 regulator? Which would be best for single tank, warm water, with potential for Tec use in the future? Thanks for any advice.

In the old D9, you have to press the air button and wait a few seconds for the AI to establish connection. Sometimes, the user forgets to do this and proceeds with the dive. The AI then doesn't give any air time data. In the new D6i, is the AI sync now automatic when you start your descent...

What do you guys prefer? And why?

My first dive computer is the Suunto Solution purchased in 1992. This is the pre-nitrox version of the Solution. Believe it or not, it's still working and accurate when depth and temperature are compared with other modern gauges in deep tech dives. It's quite amazing how these things are built...
