Sidemount - SPG and Transmitter - HP Splitter? Button SPG?

[EKKsoldier622]

DGX Button Gauge + Transmitter.

I do this with AI on a HP splitter plus a regular short hose+SPG combo.

Analog SPG will never have a flat battery or sensor failure.

No harm in using both SPG and AI. When the AI works you get some useful data, but technology failures still happen.

I do some work with a specialist embedded electronics company, and even with 100% QC testing there are still some returns because of intermittent or total component failures.

Electronics are not a perfect substitute for analog systems.

There’s a whole bunch of reasons not to, but it starts with “your SPG or transmitter is already your backup to your planning.” These multi gauge or tx solutions are inelegant and unnecessary, to ignore the worst of both worlds.

You should apply the same reasoning to carrying multiple torches

…I can’t plan to have sunlight in a cave. Do you plan to have sunlight in a cave?

Do you see people using two SPGs on a set of twins, whether in the ocean or in an overhead environment? Let’s ignore the fading independent doubles bamboozlery but I certainly haven’t, whether in N America, Europe, or Asia. Why use an SPG and a transmitter?

For me personally, in a choice between relying solely on analog or solely on electronics, it’s analog every time.

Each transistor, cpu, gpu, resistor and sensor is a potential point of failure. Analog systems, particularly for measuring pressure, are very simple devices.

Perhaps you think of AI as being a single device, when it’s a composite unit made of many different individual components, each of which has its own potential for failure.

Yawn.

What have you seen fail more, spg or current versions of ai?

Which has the more severe consequence once it does fail?

That was rhetorical, answer not needed

For me personally, I have had one transmitter and one dive computer fail at different times. I have never had an SPG fail.

If you are experiencing a high frequency of SPG failures due to impacts, perhaps you should consider rubber cases for them


I have sime experience with electronics manufacturing. When individual electronics components are sold to manufacturers there is some disclosure of the expected percentage failure rate. By the time the composite device with multiple such components is sold to us consumers there’s no disclosure of expected failure rates. This leads to a mindset where too much confidence is placed in the absolute reliability of the device, which is inherently prone to some low percentage of failures.
