Voting logic doesn't make sense to me. It seems like most rebreathers that use 3 cells (or more, some can take a ridiculous amount of cells) and employ "voting logic" if they use a solenoid. From what I understand, voting logic finds the two cells that are most alike and then averages them...

I am not a rebreather diver. I don't own one and have never piloted one. However, I am fascinated by the mechanics of different rebreathers. Of particular interest to me are hCCRs like the rEvo when configured as such. I have a question regarding the constant mass flow of oxygen into the...

Currently, the OC Tec mode allows the user to specify an alternative data display to replace the NDL display in the bottom right. This is because once the NDL has been reached, the NDL display is useless and wasting space. I would like to point out that the deco stop displays (depth and time...

I recently got a Perdix and I love it. However, I have a question about the OC Tec layout. The NDL displayed in the bottom right can be customized to display other information once the NDL has been surpassed as it would otherwise waste screen space. But what about the stop time/depth in the...

Before I say anything, I wont name the dive shop that certified me but I would like to commend them. They really did do an excellent job tailoring the class to the individual's needs and making sure that everyone is safe. My question is specifically derived from one exercise performed during...

I have a hole in my eardrum approximately 1.5mm in diameter and currently have a slight infection. I may be stupid, everyone might laugh at me, and most will say to stay out of the water for a good long time. I do not believe this is an option for me, and I am going to try to get back in the...

My current setup consists of a steel backplate and doughnut style 25lb wing. I use weight pockets on the waist straps of the backplate harness so that I can travel and easily throw in a couple of lbs for salt water on the boat. In the pool, I use no additional weight, though I intend to wear a...

My understanding is that heavy fins are great when you are in a drysuit, as your legs become rather buoyant. Right now, however, I want to dive with a simple rashguard and swim shorts as I am mostly diving in very warm water, but plan to do cold water diving in the future. Since wetsuit...

I've been saving for my first set of regs for a bit now and I have narrowed it down to the following two choices. I have only listed the pros and cons that I see as being different between the two. Poseidon Xstream Pros Can buy two first stages and two second stages, new, with hoses, with a...

I ask this merely out of curiosity as I am just a very green OW diver. I am interested in the principles underlying various equipment setups and I have come across a bit of a question. I may not have all my facts straight but I will explain my question as I ask it. I am probably missing...

I am comfortable in the water but I have very few logged dives and do not yet own all of my equipment. I want to invest in gear that is durable, will last, and I will not replace if I move into other types of diving (which is thus far my intent once I reach about 10 to 15x as many logged...

I am a 26 year old male that has recently taken up an interest in diving. While I am inexperienced, I am advanced open-water certified and I would like to gain more experience and potentially pursue commercial diving as a career. While I am no athlete, I am in good physical health, a strong...
