Are Suunto Zoops super conservative?

My recent biggest issue with the zoom isn't the conservative side, but the safety stop timer. It does not count down the seconds and in the event you have swell, it will restart. This was frustrating to me with my cousins sons because they were taught to do 3 min (and you should) but those stinking computers reset more than once and our 3 minute safety stop was over 5 minutes. Needless to say, the 14 year old was worried about his air and they didn't understand. But they were not coming up. It is too sensitive to swells and I don't like that you can't change the safety stop depth. Other than that, they are great for novice and experienced. I don't like them myself as I like a little more options with my dives.
I agree the lack of displaying seconds is a pain. What I have experienced is that it does not reset but when you dip below 20' it stops counting down until you raise back up.
 
There is a saying in technical diving.

Dive planning is measuring with a micrometer, marking with chalk, and cutting with an axe.

If you are worried about a computer counting down seconds on your safety stop, then you really don't understand the level of precision and its importance in this process.
 
I am not worried about it, it is just nice to be able to see how long I have left on my safety stop. With my Oceanic it shows how many seconds I have left, with my Suunto if I have not been watching it and I glance at it I could have 2 minutes or 1 minute and 1 second left.
 
Don't understand the importance, why the rush to get up on the second? Especially when you had a deco stop, nothing wrong with an extra one or two minutes even after the deco clear came on. Even if you do the satfety stop you should rise slow to surface adding another near minute.
As for the concervatism, I agree with some of the post, if you dont like it, use a dive planner and set it to guage mode and work of your dive planning.
 
My experience with Suuntos has been that they are pretty fair, if dived well. What will really limit the NDL they suggest is if dived poorly (saw tooth profile, fast ascents, short SI etc.).

I dive a few local dives a year but my diving is primarily on vacation at resorts or more lately, liveaboards. I dive a minimum of 3 tanks a day, usually 4, and on the rare occasion, 5 tanks a day on nitrox when available in 7 day back to back stints. I have been diving with a Suunto for the last 120 dives or so and it has served me well. It is definitely conservative compared to others; however, in general, it has not hindered my diving in that I have to be shallower than others or come up before others. There was one occurrence recently where I did notice it’s conservatism - we were doing muck dives to 80-90 feet on nitrox and doing 70-80 minute dives 3 times a day with shorter surface intervals because we were on a dayboat from the resort. On the 3rd dive of the day, I was getting to within 3-5 minutes of NDL but once I crept up to 45 feet or shallower towards the latter part of the dive while on 32% nitrox, it wasn’t an issue anymore. That was where the rest of the group was going already so it didn’t throw a wrench in my plans. Additionally, I was still the last one up from the dive in my group (hooray for good air consumption!) after splashing at the same time.

As stated, they really do not like sawtooth profiles, fast ascents, and short intervals and will definitely penalize you on subsequent dives even more if you repeatedly do this and/or also ignore their recommendations. While it’s frustrating and annoying to some, I think not doing these things that it will penalize you for are good, safe practices for diving anyway - so I am happy to avoid it. :)

I agree having the seconds is nice. I dive two computers and the other uses seconds.

They must have been big swells. Usually the stop coninues unless you exceed the floor.

Sounds like a good teaching moment for the cousin's sons about priorities and what is and isnt important about safety stops.

You have left as long as you can hang there. I have this vague feeling that RGBM-based algorithms in basic DCs reward you for longer safety stops and the longer you spend around 5 metres, the less "conservative" they'll be on subsequent dives.
 
. . . those stinking computers reset more than once and our 3 minute safety stop was over 5 minutes.

Even if I were to think like a 14 year-old and have it in my head that I MUST complete a 3-minute safety stop, if my computer were to count down to "1" minute and then reset to "3" because of a swell, I would like to believe I would remain there an amount of time that feels roughly like another minute to me. Most of us are pretty good at estimating how long a minute is. Even a 14 year-old should be able to time a minute in his head. Perhaps this is a symptom of the younger generation's over-reliance on electronics?

I don't understand those fitness monitor things, either--seems to me I can judge how much exercise I'm getting from how I feel. I don't need to know I walked exactly 14,287 steps to know I got my day's exercise.

I don't believe Suuntos reset to 3 if you go out of the 10-19 foot range they give you for your safety stop. I used one for years, and if I did stray out of that zone momentarily, it would just stop counting off the time until I returned to the zone. If you get right back to the zone, it should only cost you a few seconds.
