NB 1: This post is probably only interesting to those who conduct deep rebreather dives OR anybody who just wants more information about how the rEvo rebreather works. NB2: Most rebreather divers should never need to do this. Please don't modify your system unless you know how (and why). I'm supplying this for any rEvo [...]

DiveX “Smart Slice” Pressure Sensor Repair
Background As I've said many times, I have a "love / hate" relationship with scooters. They are very useful tools and IMHO increase safety on deep dives -- but there is a tradeoff in complexity, additional gear, etc. I know some people who have mastered using a scooter and camera at the same time but [...]
Antarctica Packing List
Note: This is probably more in depth than the "casual reader" probably wants but I wanted to document what I brought to help future Antarctic trip travelers -- especially those diving or doing photography. The ice was here, the ice was there, The ice was all around: It cracked and growled, and roared and howled, [...]

Shearwater Feature Request – “Vote Out” a cell
(NB: This post is targeted at rebreather divers) The purpose of this post is to detail the situation when you would want to manually "vote out" a cell on a Shearwater computer and alternate solutions considered. Background The way I have my rEvo configured is that three oxygen cells are connected to the main Petrel [...]
LP50 Bailout Tank
NB: This post is probably not very interesting to non-divers. Background Believe it or not, I have recently been (gasp!) doing some rebreather dives at recreational depths, such as building a photogrammetry model of the Yukon and model of the Corsair south of Pt Loma and I have a few other projects at that depth [...]
Shearwater Petrel2 Updates – V93
I had recently written about the benefits of Shearwater making the SurfGF field persistent after clearing deco but was also waiting for that change to be "back-ported" to the Petrel2 hardware. I noted at the end of the article that a Shearwater support engineer said they were going to make the changes available in the [...]
Shearwater NDL Replacement Field Persistence
Background I recently read the release notes for the latest Shearwater software release (v91) and was excited -- yes, I know, no comments from the peanut gallery. One of the standard information fields on a Shearwater computer (all dive computers really) is the NDL or No Decompression Limit field. This is the amount of time [...]
Shearwater Live Deco Plan, Part II
Background This article is about a "feature" in the Shearwater diver computer that I believe most people are unaware of and that is not really documented in the user manual. It is about the "Dive Plan" feature which divers probably most often use to plan a dive before they enter the water; however, it is [...]
The cheapest rebreather accessory you will ever buy…
The rEvo rebreather has a nice "bar" across the top to facilitate carrying the unit and securing it to the boat. I've seen people use all kinds of different methods to secure their rEvo to the boat. They include bungees around the 3L tanks that stick up (which doesn't seem all that secure to me), [...]
