What computer we use?

I used three brands of dive computers, Cochran Dive Computers, DiveSoft and AV1. All brands are well established and use well proved algorithm:

Dive Freedom

(DiveSoft) computers are state-of-the-art instruments that emphasized on the user interface and robust material design. Use a well proven decompression model (ZHL-16) with the possibility of setting gradient factors and Pyle stops, contains easily operated buttons and  precise mechanical design.

Four software choices are available, all corresponding to the training levels of the majority of the training systems. All you need to do is buy the upgrade code software and unlock its potentials. All is made over the internet with your dive computer and pc. Also used a rechargeable Li-Ion battery and TTF display.

For more information read the Data sheet.

Price will depend on the model, form US$619 up to US$ 989.

If you have any question, feel free to doing so below.

You can buy Divesoft products from me, keep in mind that this is a small business but I will teach you how to use it, manipulate it and how to take advantage from it knowing all its resources.

AV1 Dive Computer

A look into the past (updated November 2019)

Cochran is no longer actively selling diving computers, so it’s behind in the past. But nonetheless it is a one of the best design ever made and robust. Overall what I loved “the most” was the algorithm and its implementations.

The conceptual design was very distinctive from the rest, Cochran has a military  mindset and other brands has a tech-recreational mindset. That doesn’t mean that Cochran wasn’t used by recreational divers; by all means, I used it in countable dives with strongly success. But the “automatic switch” between gases was a concept that not everyone understood and didn’t know how to use it.

I still use all of my Cochran Computers. Anyway, If you want to grasp one of these computers, maybe I can still do something for you or look into their website.

Cochran sold it last model in $US 700 directly on the website
