Truth Aquatics - 3500 PSI fills on the boat?

[anchochile]

I'm going on a Channel Islands trip on the Truth next month, and am thinking about what tank to bring. Their website says their compressor can fill up to 3500 PSI, so I'm thinking about bringing a steel HP80 or HP100, but I saw mention on some older threads that in reality people were getting 3000 PSI fills.

Can anyone confirm whether I can expect to get a true HP fill on the Truth? I'm inclined to assume so, since it's what the website says, but would love to make sure.

you don't get 3500 unless you want to skip dives and wait for your tank to cool. they do pump to 3500 psi, but once it cools you get closer to 3100.

... I'm thinking about bringing a steel HP80 or HP100,....

I've just rented steel LP95's from that dock side shop that's 10 steps from the boat (at 11pm at night). The LP95 at 3100 psi is 122Cubic Feet of gas. Your HP100 at 3100 psi is only 88 cubic feet.
Get the LP95,,you'll need and enjoy that extra gas

Hmm...a HP80 at 3100 PSI would give me 72cf, which is still more than 64 I get from my LP72 at 2250psi. But yeah, a LP 85 or 95 might be a better bet. I'll see if my LDS rents them, but if not the dockside shop is probably the answer.

This is a beginner-oriented trip and most folks will probably have AL80s, according to the trip organizer, so I'm thinking a LP85 would be plenty.

What @runsongas said above. 3,000-3,100 is a more typical fill. Whichever tank you go with, get a steel one- you'll be happy to not have to carry as much lead weight around.

Hi folks - resurrecting this thread. I'm trying to decide between a LP85 and LP95 for this trip. All my dives so far have been shore dives with Steel 72s. Even with that "small" tank, I find the hike back up the stairs from the beach to be a slow and difficult slog but manageable. I'm a smallish guy, 5'8" and 145lbs. Once in the water of course the tank is no problem.

But I imagine for boat diving, the weight of the tank on land only matters for the few steps across the deck before giant-striding into the water.

Given that, I'm trying to decide if it's worth going for the larger LP95 over the LP85. Am I likely to regret the additional bulk and mass of the larger tank? As a wetsuit diver, will I be limited by cold rather than air? Will the extra size of the LP95 make it more annoying to swim with underwater as well?

Any advice is welcomed!

Are you planning on diving Farnsworth Banks?
Are you an air hog? If your answer is no to both those questions then maybe you don’t need more gas since a lot of the kelp forest dives are 45 to 60 feet with the occasional 80 thrown in.

But I’m a girl, I sip, my boyfriend had a steel 95 for those dives, I had a 72. Definitely go with steel.

It's a beginner-oriented trip to Santa Cruz & Anacapa, I think max depth will be 50 fsw for most dives. Seems like LP85 is probably the way to go.
