Need advice on light warm water equipment

[akulamd]

Hi folks!
My wife and I are experienced scuba divers who have been diving for several decades. Herein lies the problem - we have not updated most of our gear for about 25 years!
We both have old Zeagle regulators, I still have my old Zeagle Ranger BC.
We live and dive in SoCal and it works for us. However we also travel to the warmer water and would like to get lighter setups. Any recommendations for light setup would be welcome.
Parameters I consider when buying setup are:
1. Lightweight
2. Reliable
3. Easy to fix, with spare parts available worldwide.
4. Comfort is somewhat less important. We are easy.
5. Price is also not a major consideration since we keep our equipment forever and the cost is amortized over decades and thousands of dives.

We are heading to Australia and will be going on live aboard as well as crisscrossing the country. That is why the weight is of paramount importance.
Thank you in advance for recommendations.

What's the matter with the stuff you've already got?

Quality dive gear can last longer than you will.

When you're underwater it doesn't really matter how much the stuff weighs, if you get lighter gear you'll need more weight.

As long as your regulators are still doing the job, there is no need to replace them, just get them serviced. I have been diving my Mares MR22 Abyss for over 20 years.
Look at the Dive Rite Hydro Lite BCD. Dive Rite have dealers world wide. Hydro Lite BCD - Dive Rite | Equipment for Serious Divers

He appears to be experienced enough to know and understand that.

I've dragged my gear all over the world too, including a 19cf pony bottle, it's regulator and a fill whip so I don't have to deal with it being out of hydro.

But sometimes I leave most of it home and just bring my mask, computers, torch and camera.

One of those times was a liveaboard out of Cairns, Australia, one reason being the gear was included in the cost of the trip at no extra charge.
