Are there any conerns or problems with the mars2AAD?

Recommended Posts

Not only is it the cheapest AAD, but the batteries never need changing and it never needs servicing. Almost seems too good to be true. What’s the point of buying a vigil or cypress in this case? What are your opinions on the M2?

Anything that runs off of batteries will eventually run out of juice. As a matter of fact m2 is the only AAD currently on market that allows you to check the battery level.
The downside of using "exotic" parts or gear is that not everyone may be familiar with it.
Case in point: just last week I had a customer bring me a rig with m2 in it that still had cutter that has been recalled with SB in 2016. Rig was kept in date the entire time...

The Mars is great. It’s not true that you always get what you pay for. There are plenty of overpriced products out there and the Mars unit is just as safe as any others. In my opinion it’s superior to other options as it has a much better screen that is easier to use and configure.

I am very happy with my M2, especially what I percieve is an actual safety benefit of not having to take it out for service. 

For myself I think the Cypres service intervals decreased safety, because I didn't end up renting a unit when mine was out for service, and I would continue to jump the rig while it was out.

A new Cypres has the same 15-year service life as an M2, and the 5- and 10-year checks are optional.

Likewise I had two vigils that were 12 years old and had been installed/repacked despite a SB stating that they needed to be replaced at 10 years.    Repacked by riggers in both Canada and Eloy.

Dont blame the M2 because a rigger doesnt check for SB’s and ensure compliance.

The cypres does have the benefit of being in warranty for the entire lifetime if you get it serviced as recommended.

The mars has a 2 year warranty. If the battery on a mars does need to be replaced, even though the mfg says it should last 15 years, it would presumably not be done for free. It is great that it shows the remaining battery life left, and it also shows the pressure the unit is sensing for confirmation to a local barometer. If that pressure check is not within the recommended tolerance, then presumably fixing the unit would not be free.

Of course the 15 year warranty of a cypres comes at a cost, and most never need to get their AAD fixed at any time during their life. I think we should acknowledge the trade-off when discussing cost comparisons.

Another point worth acknowledging is a Cypres can seem to have no problems at all, no problems during the start-up self-test, and then when SSK does the full series of tests including accuracy/resolution at the fire/no fire limits, high/low temp, vibration, etc it fails to meet the original standards and requires repair before returning to the customer. Does this mean it would have necessarily failed to save your life if needed? No, but it does mean that the mfg is not comfortable with the self test being the only check on the proper function of the unit, and for very good reason - some fail! The self test can't check things to the same extent as can be done at the factory.

The self test cannot simulate a jump (simulate the pressures on the transducer) to test the entire system, and cannot test it in harsh environmental conditions. It just is a partial check of the health of the electronics.

If cost for an AAD is critical, then getting a used unit is also worth considering. If a used unit is bought at the right price, then the cost/year should be about the same as if buying new. I hear finding used units at the right price is the challenge.

Spoken as the true Airtec lover and defender you have always been here. Two points. Airtec no longer requires, only recommends 5 year servicing on the new units. Which means that almost no one will bother, making one of your points moot. And the other thing is that the demand for used AADs far exceeds the supply. This makes buying a new one the cheapest option on a per year cost basis.

My point about getting a used unit applies not just to Cypres. I understand that the used market is tight. Sometimes the per year cost matters less than the "right now" cost. For some, the desire to have a predictable cost (warranty that lasts) is important.

I am a fan of the Cypres, but will be considering others when I need to replace mine in few years. The competitors definitely have some advantages, as I have mentioned. I even bought an Astra way back when I returned to jumping after several years away. Fortunately others persuaded me to reconsider and I was able to return it. Back then the only other choice was the original version of the Cypres. The exchange rate at the time allowed me to buy it at perhaps the lowest price ever.

I agree. I won't even put my name to a repack on an Astra anymore. I don't mind orphaned canopies with no support, but Astras and even Argus? Find someone else.

If you look at the cost per year to own any AAD, and amortize it over it's life, the cost difference between the best and the worst is very little.  Why not own the best.  Maybe one jump a year difference !

Mostly because you don't pay yearly. You pay one time up front and the difference is far more than one jump. As far as owning "the best", I have seen nothing that makes me believe that any are better than the others.
