Looking for back up bottom timer

[TigerDiver8]

Also, might look into why it's not a good idea to have 2 different computers (algorithms) with one as a back up. I can highly recommend the petrel 2. Also, you could consider just a bottom timer and ratio deco as your back up.

Cant I just put it in gauge mode while diving with both

True, but then it's not a back up computer....

So I should look at getting another luna?

Adjustable algorithm to more closely match yours, $200.

It is a 1-button though afaik. But realistically how often are you going need to change it once set.

Yes or one with a similar algorithm.

The pros would include you already know how to use it. The learning curve and keeping things straight between the two can be a hassle. Differing algorithms and the way they are implemented can be disconcerting. The cons would include cost, especially if you outgrow the capabilities and/or want some new feature in the future.

haha yeah I guess you are right. I am looking for a simple Back up Computer. Although I cant stop looking at the Petrel 2. I really like that computer. haha


Thanks Jim, but dmaziuk is right, not looking for just a bottom timer.

Thanks for the heads up about your buddy though.

Go with the Petrel 2.

If you are going to spend the money, get a good computer. You can install what you like in the Luna, and you can set the two so that there times are near identical.

If one craps out - or as happened to me, the strap broke - you still have all your tissue loading on the other.

BTW, the rubber straps on Galileos are crap. Put on a slip noose that ties to the computer, so you have a backup if something breaks.

I normally agree with you 100%!

However, I dive a Sol and a Petrel and learning the Petrel is super easy. Both of them (Petrel and Luna, that is) will grow with the desires of the diver.

I used to dive with TWO Aladin Pro(air & nitrox), unfortunately the AIR computer died several months ago. Therefore I bought a Veo 180(US$150.00) on line. The Aladin Pro Nitrox is the more conservative one so I use the Veo as back up.

I was referring more to new features unavailable on the market today. Software upgrades can only go so far. Faster processors, longer battery life, brighter displays, better user interfaces that depend on hardware changes, and smaller profiles come to mind.

More far-out would be displaying blood gas levels (the Luna can already display heart rate), O2 in several cylinders as well as pressures, automatic logging of visibility (only nice to have but sort of neat), a built-in GPS display that is available on the surface, a built-in emergency flasher, a built-in PLB (Personal Locator Beacon), a built-in camera on-par with a smart phone, a built-in VHF radio so you can talk to the boat and/or call for help, a body core temperature display so you can monitor hypothermia… I better stop now.

One feature that most divers would find useful is long range acoustic transducers that allow tracking other divers, you to track the boat, and the boat to track you… more or less like the Liquivision Lynx. Oh God, just as long as they don't install a app for Facebook!

Another problem is the implementation of the same decompression algorithm on computers from different manufacturers can vary -- manageable but disconcerting to some people.

Have another vote for the BUD; it would seem to fit what you are looking for.
