I can get a Hollis TX-1 on eBay for about $350.00. Would this be a good deal? And would it be a good backup to my Perdix AI? Thoughts...
 
@tbone1004 Because I can. Do you not have a backup computer?

short answer no.

long answer, is yes I do technically have a Nitek Q that is a backup computer, but it was given to me and doesn't come in the water with me. I also will take my Perdix AI with me when I dive my rebreather, but only so I have the AI function. Most guys I know won't bring a backup with them unless it's a monster size dive

I met a tech diver on a boat once. I asked him why he had two of everything (shears, computers, you name it). His reply was, "Two is one and one is none." Sounded pretty safe to me. I would hate to end a dive because my computer futzed out.

doesn't mean I don't carry tables and/or know how to use ratio deco, but I don't use redundant computers under "normal" dive circumstances. Controversial? to some, but it works for me and most all of the people that I dive with. That said, you have one of the most reliable if not the most reliable computers ever built. Odds of it failing? pretty much negligible
 
I always carry a primary and backup computer. So does my girlfriend. Both air integrated and synced to the same tank transmitter. I also keep a spare transmitter in my dive tools kit.

Why? Because it's worth the cost of the second computer to minimize the possibility of a lost dive or 2 or perhaps an entire dive vacation being affected.

Electronics fail, battery compartments flood.

It happens. Considering the amount of money spent on dive gear and dive vacations the security of a second dive computer is a relatively small amount of money well spent.

Never needed the backup transmitter but between my girlfriend and myself we had 2 computers flood over the course of 5+ years, about 150 combined dives.

I have my Zoop right now hooked in with a compass and SPG. So, I have a backup, but I really want to get rid of it. Also, it's not AI. I think the TX-1 would be a good backup and it would sync with my current transmitter - at least from what I have read.
 
all this talk of redundancy, yet no one seems to buy into my recommendation of buying a doubles regulator set instead of singles so you have a spare first stage on the dive boat for the same reason with talks of "global service".... curious
 
Hi @Snoweman

Yes, the Hollis TX1 will work with the PPS transmitter you use for your Perdix AI, see post #6 Are Pressure Transmitters compatible across brands?

The TX1 could be a good backup for your Perdix. It runs the same deco algorithm, Buhlmann ZH-L16C with GF. The TX1 has 5 preset GFs and allows custom GFs to a maximum of 90. It might be a bit more conservative if you are running a GF hi of 95 on your Perdix, other than that, you should be able to match your Peridix GFs.

I believe @stuartv had a TX1 for a while, he might be able to answer questions

Good diving, Craig
