Where did you solo dive today?

[34109411]

Rothsay wreck Prescott Ontario : water temp 70 air about the same. Two dive of about 45 min msx depth 30 feet. Viz was maybe 5-10 feet at the most 15.

Dive one

Following the line to the rothsay from shore it s about 300 yard out. Didn't reach the wreck but doesn't matter was very fun. I swam for about 15
min and than turn around and practice skills, mask removal and swim, swap to pony regulator, dsmb deployment.

Dive two was about the same but for some reason a sip a fair amount of water while inflating the dsmb so start coughing down there, took about 30 sec and i was ok to catch my breath.

I dove on steel 100 i just needed 4 pounds of led.

Overall a great day, because it was my first time alone on that site i dove very conservatively i finish both dive with more than 2000 psi.

Next day of diving will be next friday.

Be safe.

Poor Knights Island New Zealand. Two solo nitrox dives off Calypso with Dive Tutukaka. First dive to 21.1M for 50 minutes, second dive to 26.6M for 49 minutes. Water temperature was 17 degrees. Very clear water.

What a nice day of diving today ! Water temp 21 C. Air temp 30 C. First dive 45 min. Second dive about 35 min. Max depth 30 Ft. Lots of fish cause water is warming up. Viz was as usual 5-15 feet depend.

Had some kind of leak on my poney nothing to worry about LDS fix it for me for and even fill it for free.

I met another solo diver down there we share greetings and went our separate ways.

Next of diving will be next friday !

Brockville Ontario. Centeen Park.

Cane Bay Wall. 2 dives. Enjoy how the world simply vanishes into the abyss. Still enjoy the variety cruising at 45'. Surface swim to the mooring ball, then dropped in. Found the Carousell horse both dives. Several Grouper, Southern Sting ray, Turtles. Nice large Green Moray at 125'. Delicious Tuna served by Wynn at The Landing between dives.

Not today, but yesterday I dived Yellow Brick Road in Hollywood. My buddies bailed at the last minute which led me to change plans from diving in Ft. Lauderdale, to staying local. (not that Ft. Lauderdale is that far away). YBR is my favoritist dive site and I've been diving it since I got certified back in "93. Log books keep me honest, and yesterday was dive #196 there. If you asked me, my guess would be at least 100 more.
There is a fish there. Stumpy. I first photographed him in 2021 with a raw pedunckle and no tail. Then I saw him again. And again. For over a year I saw Stumpy. Then he disappeared. Gone. Or so I thought. A year later, I see him! He is bigger, bolder. I see him off an on for a few months, then gone again. Last time I saw him was last fall. And then yesterday. Bigger. Bolder. Boss.
Vis wasn't too good. Lots of particulate in the water. I like this photo cause it looks like bling! Stumpy is a star!

Nice this morning! first dive about 50 min second dive about 40 min. We got that tail from that hurricane rain was pooring for the last 2 days. Visibility was 0 ! Could not see more than a foot in front of me but i like it ! Practice lots of drill during the first dive. Calculate my sac rate at 26 psi per minute does it make sense ? Need to double check.

I had a problem with my compass i was getting deeper and deeper to get back to shore ? The problem is always the compass right ??? For somes reasons was kind of going around and around at 40 feet ish, i finally get the bearing i was looking for and make it right on at my exit point.

Next friday we do it again !

Brockville, Ontario

... Calculate my sac rate at 26 psi per minute does it make sense ? Need to double check. ...

We need to know your cylinder. For example, 26 psig/minute using an Al 80 yields a different SAC rate than, say, 26 psig/minute using an old-school PST 72.

ETA:

1. For the Al 80, solve 77.4/3,000 = x/26 to get your SAC rate x in cubic feet per minute (cfm).
2. For the 72, solve 71.2/2,475 = x/26 to get your SAC rate x in cfm.
3. For my HP 100, solve 102/3,500 = x/26 to get your SAC rate x in cfm.
4. For my HP 120, solve 122/3,500 = x/26 to get your SAC rate x in cfm.
5. Etc.

80 AL

 

[34109411]

starting pressure 2584
ending pressure 2029
dive time 10 min
depth 30 feet

2584-2089/10 = 55.5

33/33+1= 2 ATA

55.5/2 ATA= 27.75 psi per minute

So using the 1/3 rules if i am planning a dive at 30 feet using and Al 80 i will have 72 min of gas :

3000/3= 1000 psi

3000-1000=2000 psi usuable gas

2000/27.75 psi per per minute = 72 min dive time

Are my calculations are ok i am not an expert please feel free to chip in.
