Results from SPG & Transmitter failure survey

[Wants2divemore]

Thanks to everyone who completed my survey about SPG and transmitter failures. Here are the results:

Number of respondents: 61
Divers who've never used an SPG: 0
Divers who've never used a transmitter: 17

Total number of dives with an SPG: 49,353
Total number of dives with a transmitter: 18,503

Total number of divers experiencing an SPG failure: 24
Total number of SPG failures: 67
SPG failure rate per dive: 0.14%
Percentage of divers who've ever had an SPG fail on a dive: 39.34%

Total number of divers experiencing a transmitter failure: 15
Total number of transmitter failures: 47
Transmitter failure rate per dive: 0.09%
Percentage of divers who've ever had a transmitter fail on a dive: 34.09%

Unfortunately 61 respondents is too small a sample size to make any meaningful conclusions. Since only one person has responded since the end of May, despite me bumping the thread, I decided to publish the results now. I imagine that many people who've not had an SPG or transmitter failure chose not to respond, which would increase the failure rate.

Feel free to interpret the data however you wish.

Wut???

That's a ton of failures for the amount of samples (people) provided. That says a ton.

2 is 1, 1 is none.

It would be worfh sharing with FB groups or getting the influences to shill it

Without knowing the brand of transmitter (for example, Suunto vs PPS) the data are pretty much meaningless for failure rates of transmitters. But 67 SPG failures out of almost 50k dives seems like a small number.

Where is this survey? Link?

There might be selection bias: those who have experienced a failure might be more likely to answer the survey, versus the general background population of all divers, or even everyone who noticed the survey.

The comparative statistics between SPG vs transmitter seem useful.
