About Oceanic VT 4.1 Wrist Computer & Transmitter with PC Download

Interface advancements that change the face of dive computers: The Oceanic VT4 1 takes yet another step forward in continuing a reputation of ruggedness and reliability while making advancements in Personal Dive Computer (PDC) usability. The VT 4.1 Dive Computer out-of-the-box ready for your dive today and ready to follow you onto more advanced dives in the future. With Oceanic's wireless transmitter, the diver can also monitor gas pressure from up to four independent cylinders ideal for both technical diving applications and recreational diving.

The choice is yours:
The debate about a dive computer's algorithm is over. It is no longer about whether an algorithm is right-or-wrong, liberal-or-conservative. It is simply about what is right-for-you-at-the-current moment. You no longer have to choose a brand-based on your decompression algorithm preference. Oceanic's given you the choice depending on who you're diving with or the kind of diving that you're doing, with the first dive computer powered by our exclusive dual algorithm.

The Oceanic VT 4.1 is an advanced all-in-one dive computer featuring Oceanic's exclusive dual algorithm, wireless air-integration, digital compass, remote buddy pressure check, and so much more. The VT 4.1 Computer is powered by Oceanic's Exclusive Dual Algorithm - Your choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis). This wireless air integrated technology system with advanced 3-axis digital compass with full tilt compensation and can switch between 4-independent transmitters, with up to 4-nitrox mixes to 100% O2 will meet all your today diving needs and those in the future!

When diving the computer has deep stop with countdown timer, gauge mode, norm (Air/Nitrox) gauge, and free dive modes of operation. The computer is water or push button activated. Want to customize your own-safety-factors? The VT 4.1 Computer provides personal conservative factor adjustments (PCFA). Each level of the PCFA provides no decompression limits for the next dive +3,000' (920 meter) altitude adjustment.

The computers altitude algorithm is based on the NOAA model and provides altitude adjustability from 2,000' to 14,000' (610 to 4,200 meters). The computer has an operational (NORM/Free Dive Modes) depth of 330' (200 meters) with a (Gauge Mode) depth of 399' (120 meters). When in low light conditions the VT 4.1 is equipped with Ocean-Glo backlight with an adjustable duration function. The computer is powered by a CR2450 lithium battery that can provide up to 300-dive hours. The computer allows battery hot swap to retain-dive-data along with a graphic low battery indicator and Smart-Glo backlight sensor. With the transmitter you will be able to take advantage of all the wire-less air integrated functions of the VT 4.1 Computer. When coupled with the transmitter the VT 4.1 provides the following unique features:

Air Time Remaining:

The Air Time Remaining feature calculates current depth, tank pressure, breathing Rate, ascent time, and decompression status to tell exactly how much time you can remain underwater. The VT 4.1 Dive Computer continually displays air time remaining via a numerical bar graph in addition to cylinder pressure. You may also display air time remaining in oversized digits at any time with the press of a button.

Dive Time Remaining: Dive Time Remaining, like air time remaining provides a 'real' number in minutes. This calculation combines air time remaining, nitrogen and oxygen absorption, displaying whichever allows less time.

Other features of the VT 4.1 Computer are alarm acknowledgment, ascent rate range, ascent rate maximum, decompression capacity of 10' to 60' (3 to 18 meters), deep stop function, automatic safety stop prompt, cylinder pressure, audible alarms, calendar/clock, 24 hour time to fly countdown, calculated de-saturation fly countdown, dive mode displays, high O2 and PO2 alarm/warnings, 24 dive on-board log capacity (99 in Free Dive Mode), temperature display, nitrogen and oxygen tissue loading and loading bar graphs, no decompression time remaining, O2 time remaining, variable ascent rate bar graph, set max depth alarm, FO2 value (%) for 4 gases, max PO2 alarm, free dive settings, unit of measurement setting and much more.

The computer is powered by a user replaceable 3-volt CR2450 battery and the transmitter is powered by a user replaceable 3.6-volt CR2 battery. The VT 4.1 Computer comes with a USB cable, Oceanic Ocean log PC download, and PC setting upload, User upgradeable firmware and digital online class. Computer is covered by a 30 day satisfaction guarantee and a 24 month limited warranty.

Comments about Oceanic VT 4.1 Wrist Computer & Transmitter with PC Download:

PROS: I like the fact that you have so many features that can be customized, and the display is easy to read. The computer allows multiple mixes on a dive, which is handy. There is a "deep stop" function, and a compass. You can choose which algorithm to use.

CONS: I periodically have problems with the computer losing signal during a dive. The compass is slow and difficult to use. The compass also frequently needs to calibrate itself, which requires the user to spin the computer for several minutes. For this reason, I cannot recommend that you use the built in compass as your primary compass.
The menus and buttons can be a bit confusing, with so many settings, it is easy to get lost in them.
I also had the computer fail on a dive. 8 minutes into my second dive of the day, the screen went blank and wouldn't respond at all. My first dive of the day was to a max depth of 63 feet for 35 minutes, and this dive was to 56 feet. Both dives were being done on EANx32, with the computer set for air, so DCS was not an issue. Not knowing how much as I had DID concern me. Changing the batteries once we were on the surface did not fix the computer. There was no sign of flooding. The computer had only been on about 50 dives. I sent it in to the factory (under warranty), they repaired and returned it.

This was a MAJOR safety issue, and I am glad that this failure did not happen under more extreme conditions. Lesson learned. I now wear a backup computer strapped to my BC, and I have an SPG attached to my reg.

Questions about this item:

Shopper  Why Did You Choose This?
philip e  I am replacing a defective Suunto Cobra. The VT4.1 provides the integration of gas with the dive recording -- something I relied on with my old computer. I also downloaded my dives to my pc. VT4.1 supports this as well. The VT4.1 supposedly supports monitoring multiple transmitters - if so, this will be a plus. BOTTOM LINE - The VT4.1 price was the best I found for all the features supported.
Marc B  Hello, I have 2 questions : - could someone confirm that the sampling rate can be set to 1s in freediving mode (not indicated in the manual but indicated in the oceanic website specs) ? - Is it possible to manually set the water type to freshwater at any altitude (the manual says that water type is automatically set to fresh beyond an altitude of 3000 feet but says nothing about how to set it to fresh water below 3000 feet) ? Thank you very much for your answers. Marc.
Ben T  Sampling rate in freedive mode 1s and Freshwater at any altitude confirmed.
Robin W  How do you get out of the compass mode?
CADE H  Hold select button down. Button on your right when the computer is facing you and the top is up.
