Suunto computer reading wrong depth

Discussion in 'Computers, Gauges, Watches and Analyzers' started by Braunbehrens, Jun 5, 2003.

Have you had a Suunto dive computer indicate the wrong depth?

    I keep hearing about small Suunto's reading the wrong depth. The larger one's don't seem to have that problem.

    I'm just curious how many people have had this problem.

    By small I mean the D3, the Stinger and the Mosquito. The Vyper and Vytec, Cobra and Favor don't seem to have this problem.

    My Stinger malfunctioned twice like this, and I had it repaired each time. Now I don't trust it anymore. It read 140 fsw on the surface!

    Is the access hole for the strain gauge covered or protected in some way so that the salt water doesn't get rinsed out when you rinse your gear?

    That doesn't usually cause gross errors (like your 140' on the surface) but can cause the more insidious "reads 50' when depth is really 60' " sort of problem. A long soak in 100F water will fix the problem if it is just salt crystals on the sensor.

    I talked to a guy in key largo (in a small discount dive shop) the other day that said he had trouble with his stinger. he said he caused an error code and locked it up and it now won't go into dive mode. I asked why he hadn't sent it back to suunto and he said he would eventually... Things happen, but suunto seems to be pretty good at taking care of them for you. I believe a lot of these problems could possibly be due to lack of maintenance. Also, it seems to me that since a lot of people wear their mosquitos all the time as watches that they probably withstand a lot more wear,tear, bumps, and dings than the other models. If your computer spends more time above than below, salt isn't all that can work its way into them. I'm sure a lot of people really take care of their computers, but i'm sure even more never think about their care until something goes wrong with them.

    I would be interested to hear what suunto has had to say about alot of these computers that have been returned with such problems.

    I always use my computer and my depth guage. I check them during the dive to make sure they say the same. If one is wrong I check my buddies to see which one is probably correct.

    My mosquito flooded after a year and a half and Suunto replaced it no questions asked. Other then that I never had any problems with it.

    I am a guilty party of wearing my mosquito full time. Yes, it does get beaten on a little. I have had two go bad on me.

    My first one I got almost a year out of before it went to 75 feet after it got wet when I washed my hands. I took it back to the shop where I bought it and they game me another one.

    That one I took it diving once and it hung up at 35 feet. I hit the surface and it was still at 35 feet. I took that one back and I now have my third. So far its been ok. If this one dies on me, I'll take it back and use shop credit to get something else. I'll buy a watch to wear full time.

    Three year warranty is a long time considering my record with them.

    you guys ever notice how tight you're wearing these watches? Seems if they are really tight, it could possibly affect the depth reading.

    I would imagine wetsuit compression would solve that problem.

    yes, at depth, but they expand as you ascend, when this problem is accuring and not everyone wears wetsuits all the time either. The expansion of wetsuits as you descend could cause problems possibly I guess also... There has to be some reason. I lean more towards poor care of the dive computer or water intrusion into the main computer circuit or the depth sensor.

    I'm on my THIRD mosquito since February. Nineteen dives after I bought it, my mosquito went to 16' (in my computer room, no less) and wouldn't change.

    Sent it in, and 3 weeks later, they sent a brand new one. Unfortunately, the backlight on this one was bad. Took it back the next day.

    Waiting on my third. If ANYTHINGs wrong with this one, I'm getting my money back.

    My Vyper doesn't seem to have a depth problem, but I'm thinking that the temp reads a couple degrees high.

    My stinger pretty much matched my old cobra within a foot.

    seems as though any wrist mount will have trouble accurately reading the water temp due to body heat in such close proximity.

    Actually, my wrist mounted is nearly always a foot lower. My Cobra is clipped to my chest D-Ring and(if I am swimming right) should never be near the dirt. My wrist mounted is attached the hand that reaches into places to tie things off, picks up cans and such off the bottom, etc. Sometimes it actually gets near the bottom. But if it is by more than a foot, I know that I went vertical someplace where I shouldn't have. But, I know, I am just stating the obvious.:)

    For the most part, barring a complete malfunction (which I have mentioned in other posts), I have never had a problem with the depth gauge on the Suunto computers.

    Noticed yesterday that my D3 read up to 4' less than my old oceanic at depth (93' vs. 97').

    Last trip to Cozumel, on first dive at 60 ft bottom the Mosquito was reading 110. On surfacing, it still read 50 fsw. When we got back to the room, I reset by taking out the battery. It worked fine after that.

    Yeah, we have had two Mosquito's and one Stinger that we have sent back that is in dive mode at the surface...

    AT surface, displays 40' or something, and is still calculating the dive...

    We sent them back, and they replaced them... However, I have a Stinger, with over 100 dives on it, and its never done that to me. My Stinger is always within a foot of my cobra (thats just because the cobra is clipped off a little lower than the Stinger on my wrist) duh...

    But, anyways, I think I am going with a VYper for my backup gauge from now on... Stinger will be relegated for tropical diving only...

    Had a depth reading problem with a Cobra when it was new. Sent it back to SUUNTO who claimed they found no problem and also claimed they didn't fix it - but it's never been off again after it came back.

    Looks like a lot of people have problems with the small suunto's according to this poll. 1/3 of people who own a small one have had a problem.

    In comparison, only 1/14th of the people with the large suunto's have this problem.

    I like the small suunto's they are really cool....but IMO they are unreliable.

    A friend's Vytec went haywire during a dive. Still was indicating ~90ft on surface afterwards...

    Maybe...but I wouldn't blanket them all as bad. Anyone who has had a problem with their comp and noticed this thread is going to comment. I'm sure the numbers of people who didn't have any problems but didn't post are much higher.
