SPG / Transmitter failure survey

I'd like your help to better determine the rates of SPG and transmitter failures. PLEASE ANSWER EVEN IF YOU'VE NEVER HAD A FAILURE.

For this, I'm defining "failure" to be anything that occurs which prevents you from accurately determining your tank pressure for the rest of the dive, or realizing after the dive that your tank pressure was inaccurate during the dive (like your SPG needle was stuck). It doesn't necessarily mean that you ended your dive but you considered the information inaccurate enough that you didn't trust it for the rest of the dive (whether you ended it or not).

If you dive with both a transmitter and SPG, please include the number of dives with both in the answers for both question 1 & 2. For example, diver has 50 dives with just an SPG, plus another 50 dives with both SPG & transmitter at the same time, for a total of 100 dives lifetime.
Answer to question 1: 100 dives lifetime with SPG
Answer to question 2: 50 dives lifetime with transmitter

If you dive with multiple devices on a single dive (e.g. SM with 2 SPGs or just 1 tank with 2 transmitters for redundancy), please count each dive with both devices as 2 dives (since each device is being used and I'm concerned with amount of failure per device).
1.How many dives have you completed in your lifetime using an SPG (approximately)?(Required.)
2.How many dives have you completed in your lifetime using a transmitter (approximately)?(Required.)
3.How many times have you had an SPG failure? Select N/A if you never have used an SPG(Required.)
4.How many times have you had a transmitter failure (select N/A if you have never used a transmitter)?
