Does everyone really need an SPG? (w/transmitter)

[VikingDives]

I’m noticing a pattern here - the transmitter issues here seem to be non-Shearwater.

Shearwater uses the same transmitter as some other devices, their transmitter is FCC ID MH8A... It's also equally possible that transmitter issues are actually receiver issues.

Suunto seemed to be mentioned a lot.

Are Pressure Transmitters compatible across brands?

Same as a few others here. No SPG, but one in the bag.

A day trip to the local lake, if the transmitter failed I just go home. Any trip bigger than that, gauges are in the save a trip (but not the save a dive) bag. Bringing an SPG that you probably already own is cheap insurance on a trip.

Lost a week of diving due to a bad transmitter? Bad planning on your part. Easy fix. Maybe loose a dive out of a trip, but not a whole trip worth of diving.

keep it in the dive bag in case it fails, but I don't keep them on, even in a cave

YOU use AI not SPG??????????????????????????????????

I’ve been rather surprised to learn the number of cave divers who are using transmitters only. A friend did her training and has dived a lot in MX. Transmitters only for 3-4 hours dives and no issues. Of course, it’s all Shearwater computers.

I try to avoid anything with batteries in it as much as possible, in both life and water. And if I gotta have batteries, I want them powering as few of the simplest things possible.

I like my hoses. They always connect, and if there is a problem with one, I know immediately.

I keep a mini-SPG on my first stage. Lets me check tank pressure pre-dive without turning on my computer/s.

Ditto.

It depends on which dive computer you have. Not all make this information available. If it is, you'll find it under "Extra Info" with every dive.
For example on every Shearwater dive computer. Or on newer Suuntos (EON Steel, Core, etc).

That's one of the most useful posts I've come across. I now have a means of checking the transmitter's remaining power.

not at the current moment as I'm on CCR and haven't gotten a NERD 2 yet, but yes when on open circuit
