Reliability Wireless gas pressure transmitters

[Soggy]

I like the idea of 1 less hose, no pressure gauge

Why?

I have a Smart Z and run a tiny pony guage mounted on my 1st stage. Pony guage

I only have a dozen dives on my Smart Z, but have not had it drop the signal yet.

Let me know how that works out when the transmitter get's banged up against a boat or the person lifting your gear out of the water for you grabs it by mistake.

If you had a regular SPG you'd only have to take the transmitter out and plug the hole. Then you're ready to go diving.

There are many times I have considered getting a secondary DIR type guage. After all they can be had for around $59+$15 or so for a hose. There are inherent risks with damage to any diving equipment including hoses. What if someone grabs your hose and damages it? Do you carry a backup? Protecting your own equipment is the best way to prevent damage, no matter what setup you use. A loose air tank can destroy any piece of dive equipment in a heartbeat.

So the point is well taken, and I will make sure to carefully watch how someone else grabs my gear.

Today most of my diving is shallow (< 100ft), warm water with a camera.

One less hose reduces drag underwater. Replacing my dive console means it cannot bounce on the corral or get tangled up. Of course I am careful and clip it to my BC to keep it up and out of the way. One less thing to hold on to on the giant stride or backwards roll. I choose to dive with an Air2 so that I don&#8217;t need a second reg on a long hose.

I would not use this rig for all situations but it works really well for my normal dive profile.

The questions about,
1. how to avoid damage to your kit,
and
2. what backup's we should take on a dive trip
are the subject of a seperate thread.
If I was going on a liveaboard I would need to think twice about the Air2.

To me, replacing the console with a wrist mounted computer makes a whole lot of sense.

As for the SPG, here's why I think it is so important.

You can determine whether you are ascending or descending with your ears. You can figure time in your head by counting. But, you cannot determine how much air you have left in your tank without a guage.

I have the air integrated and love it, it's very handy, but I would never go in the water without a SPG, whereas, I've gone in the water without my AI working.

As to the hose creating drag, valid point, however if it is routed correctly down your left side and clipped off the drag created is insignificant and it won't clunk on the coral.

If the wireless is reliable, and I am begining to accept that it is then I might go for a mini preasure guage directly on the first stage, or a small unit clipped to the tank on a short hose. Like you I like the idea of a backup. It also allows a DM to check the air in my tank without my computer being there. Normally I set up my own gear but I have been on boats where the DM does it for you. I still check before I go into the water.
I am vearing to the mini guage directly on the first stage.

It is the switch to nitrox that is the driving force behind this change. I am not the type of person who needs the latest gear to be happy.

Not really, if you know how to configure your gear.

Replacing my dive console means it cannot bounce on the corral or get tangled up.

By all means, get rid of the console, but a properly configured SPG on a short hose (~24") has no chance of getting tangled or bouncing on the coral.

One less thing to hold on to on the giant stride or backwards roll.

With the right length hose and a bolt snap and there is no need to hold on to your SPG.

You are trying to solve a problem that does not exist by creating other potentially worse problems. Learn how to configure your gear better and you fill ind that what you think are roblms really are not.

I choose to dive with an Air2 so that I don&#8217;t need a second reg on a long hose.

That's a whole other discussion,
but your premise that fewer hoses is better is flawed. There are other more important considerations.

If you want specific suggestions on how you might configure your gear to be more streamlined, feel free to pm me.

I like the idea the of hoseless SPG's too mainly because of (a) less package/weight for travel, (b) one less hose to get in the way, and (c) wrist location of remaining pressure. The drawbacks as I see them are (a) cost and (b) reliability, so I'll stick with my regular SPG for now. A wireless transmitter would be cool, but I don't really need it, so I'll use my money for other things. Just my $.02.
