Hit 200 hours underwater last month and something felt off

I'm a inland commercial diver doing bridge and dam work mostly, and I hit 200 hours logged underwater last month. That number didn't mean much until I sat down and realized that's like 8 straight days of being submerged (you know, with no real sunlight). It hit me that my buddy Dave who's been at this 15 years has probably done over 5,000 hours down there. But here's what got my attention - my hands started feeling weird after long dives, like a tingling that wouldn't quit. Turns out my drysuit wrist seals were too tight and cutting off circulation over time. I've been loosening them up and it's way better now, but I never thought about that as a real problem until I hit that hour count. Has anyone else noticed weird body stuff after passing certain hour milestones? I'm curious about what else I might be missing.

Shoutout to the old timer who showed me the difference a good visor seal makes

Been doing salvage dives in Baltimore harbor for about 4 years now. Last month I was fighting with fogged up glass every 15 minutes, barely getting through a 30 minute bottom time. This 60 year old diver from the oil rig days just watched me struggle for a minute, then handed me a tub of anti-fog paste and showed me how to really work it in. Now I can do a full 90 minute rotation without wiping my visor once. Has anyone else had a small gear tip totally change their dive day?

Comms went dead on a 60-foot dive off the Jersey coast last spring

I was working a bridge inspection job in the Delaware River and my through-water comms unit just quit halfway through the bottom run. Had to fall back on rope pulls and hand signals with the tender. Anyone else have a backup system that actually works when your primary fails?

Rant: Kirby Morgan band mask vs Ocean Reef, found out the hard way

I spent my first 18 months diving with an Ocean Reef G-Diver because it was cheap and my supervisor said it was fine for inspection work. Last month on a job in Port Arthur, my regulator started free flowing at 50 feet and the mouthpiece kept slipping. My buddy let me borrow his Kirby Morgan 37 for the last two days and I couldn't believe the difference. The exhaust valve alone made breathing feel natural, and the communication system actually worked instead of crackling. Anyone else had a moment where you realized you were fighting your gear instead of the job?

Just realized I was tying my dive boots wrong for 3 years

Was on a job in Houma last month and this old timer looked at my boots and laughed. Said I was doing the criss cross lace method and it was cutting off circulation. He showed me the straight bar lace technique where you go across the tongue instead. My feet stopped going numb after 2 hours in the water. How long did it take you guys to figure out simple stuff like this?

Was skeptical about drysuit undergarments for 8 years

Finally tried a Fourth Element Arctic last month on a 42 degree wreck dive in Puget Sound. I was a thick wool long johns guy forever but this thing is like wearing a space heater. Anyone else resist upgrading gear for years then finally cave?

I finally compared Kirby Morgan vs. Ocean Reef masks in 40 feet of cold water off Port Townsend last week

Swapped from my usual Kirby Morgan 37 to a borrowed Ocean Reef Neptune on a 2-hour pipeline inspection. The Ocean Reef had way less fogging and the voice comms were clearer, but the purge valve felt flimsy. Anyone else find one brand holds up way better in real conditions than the other?

Overheard a dive supervisor yell 'stop breathing like a vacuum cleaner' today

I was on a job in Port Townsend last week, and this supervisor was training a new guy topside. The new guy was ripping through air, and the sup just lost it and screamed that line over the comms. It was funny but honestly, I realized I should check my own breathing too. Anyone else ever get called out for something dumb like that over the radio?

Why does nobody talk about how much current affects your welding underwater

I was working a job on a platform off the coast of Galveston last week, and the current was ripping at maybe 2 knots. I'm trying to do a wet weld on a crossbrace and my helmet kept getting pushed sideways, arc was all over the place. The vis was already poor from the silt, and with the current it was almost impossible to keep the rod stable. I spent like 20 minutes just repositioning myself to get a clean bead going. My buddy on the boat said to tie off a secondary line to anchor my body better, but I didn't have the rigging for it. Does anyone have a trick for controlling your position when the current is strong? I've heard guys use weights on their harness, but that seems risky if you gotta surface quick.

A salvage supervisor told me I was pulling too hard on lift bags and it was costing the company money

After a wreck removal in the Gulf last spring, he showed me my inflation numbers were 30% over spec and I was damaging soft patches. Has anyone else had to unlearn bad habits from dive school?

TIL I was flooding my own helmet because of a bad valve check

After 16 years of diving in the Gulf off Louisiana, I was doing a routine pipeline inspection and kept getting water in my helmet. I finally noticed the leak was coming from my own bailout valve - I had been checking the valve in the wrong position before every dive. What simple habit do you realize you had wrong for years?

Saw a guy using a 4-foot cheater bar on a 12-inch valve flange today

He torqued it down so hard we had to cut the bolts off during the morning bell. Why do people think brute force is better than using a proper torque wrench on underwater fittings?

Overheard a dive supervisor say 'just wing it' on a 60 foot repair

Last week in Port Fourchon I heard a guy tell his tender to wing it on a riser clamp install. 60 feet down with 2 knot current and we're winging it. I walked away. That's how you get bent or dead. Anyone else walk off jobs when safety gets ignored like that?

Used to tie off through the lifting bail on every small job down in Port Arthur

After a 65 foot fall last March when a cracked shackle let go on a mud barge inspection I switched to rigging a separate safety line straight to the bridle, has anyone else had a close call that made them change their whole setup?

Vent: almost had a bad day on a bridge job because of my harness

Was working on a bridge repair in Portland last month, 40 feet down in murky water. Halfway through my shift I noticed my harness D-ring was twisted under my weight belt. I had been hooking up like that for YEARS without thinking. A guy on the surface crew yelled down to check my gear and THATS when I saw it. Anyone else ever catch a bad habit like that before it turned into something serious?

Saw a guy skip his hot water pre-dive last week on a 45 minute bottom time job

Cold shock is no joke but some divers still think a quick surface interval is enough to warm back up, has anyone else seen this shortcut backfire on a deep wreck bell dive?

Hit 500 logged hours underwater last week and it hit me differently

I realized after checking my logbook that I've spent more time at 30 feet than most people spend on vacation, and now I'm wondering if that changes how I see this job long term.

Had a fish try to steal my wrench during a bridge inspection in Mobile

We were working on the underwater pilings last fall, and I set my 10-inch adjustable wrench on a ledge for a second. This big sheepshead fish, must have been 15 pounds, swam right up and grabbed it in its mouth like a toy. It started swimming off with my tool, and I had to chase the thing for like 20 feet before it finally dropped it. Has anyone else had a local wildlife crew try to 'borrow' your gear?

Wasted a whole dive day on a cheap hose clamp

I was doing a simple hull clean in Seattle last week and used a bargain clamp from a hardware store on my air hose. About twenty minutes in, it gave out and I had to surface. The boat had to pull me early, so we lost the whole job and about $800 in pay. I should have just used the proper stainless steel ones from the dive shop. Anyone have a go-to brand for underwater gear that won't quit on you?

Just realized the difference a proper pre-dive checklist makes after seeing our team's incident rate drop from 12 to 2 in a year.

Our new lead diver in Corpus Christi insisted on a printed checklist for every job, and now I won't suit up without running through it.

Spent a full shift in zero viz on the Fraser River, just feeling for bolts with my gloves.

I thought the old guy's trick for finding dropped tools was a joke

Working a job in the Gulf last year, I lost a brand new 3/4 inch socket wrench off my belt. This old diver, Frank, told me to just stop moving and hum a low note into my comms. I thought he was messing with me, but I was desperate. I floated still, hummed like he said, and felt a weird vibration through my suit. Followed it and found the wrench stuck in some silt about ten feet away. The sound waves from humming through the helmet actually bounced off the metal. I've used it three times since for small stuff. Has anyone else had a weird trick like that actually work?

TIL a lot of divers still think a flooded hat is just a minor inconvenience.

I was on a job in the Gulf last year, a simple hull clean, and the tender on deck kept telling me to 'just blow it clear' when I reported a slow leak in my hat seal. That's a fast track to an ear squeeze or worse if you're not at the right depth. I see this attitude too often, treating the helmet like a tool that can just get wet. It's your life support. A small leak means a seal is failing, and that failure point will only get bigger. I carry a full set of spare hat seals in my kit bag, not just the common ones. The ten minutes it takes to swap a seal on deck beats the two hours you'll spend in a chamber because you pushed it. How many of you actually do a full pressure check on your hat seals before every single dive, not just when it feels loose?

Had to pick between a 3mm and a 5mm wetsuit for a long harbor job in Seattle last month.

The job was a full week of underwater hull cleaning in 50 degree water. I went with the 5mm, thinking I'd need the warmth. After about two hours on the first day, I was overheating and moving felt like a real chore. I ended up switching to my old 3mm the next day and just dealt with the initial cold shock. It was way better for mobility and I could work longer without getting cooked. Anyone have a good middle ground for cold water jobs where you still need to move a lot?

My primary light went dark at 90 feet on a bridge inspection

It happened Tuesday morning in the Cooper River, and I had to finish the job with my backup. Anyone have a good brand for a super reliable canister light?
