    PADI specialties: how to choose

    First off, look at specialties that are necessary to do that type of diving. I have Ice Diver and no reputable club or LDS will let you ice dive without it. Same for deep, nitrox and wreck. If you want these types of dives, get the specialty. Then look at types of dives that either allow you to...

    Perdix AI - transmitter activation

    Someone may have been looking at both units and they got mixed up in the boxes when put away. Someone got an AI for a non AI price.

    Math is Scary - Drowning is (probably) Scarier

    It doesn't task load my brain to look at a couple of numbers and do some simple arithmetic. It also does not task load my brain to breath. Both are very simple tasks.

    Holding a safety stop - the effect of breathing/weighting

    On a recent dive I was in a up current. During initial decent the particles in the water were going up, I could feel the flow of water and felt negative buoyant. I should have been descending about 15 m per minute. However the rocks were not moving. Good hovering practice is at the end of a...

    Mix and match agencies/certs?

    All dive certification agencies (There is not not just PADI, SSI etc but over 160 different agencies out there) all follow the guidelines laid out by the World Recreational Scuba Training Council Council. World Recreational Scuba Training Council - Wikipedia The minimum standards are the same...

    Math is Scary - Drowning is (probably) Scarier

    I track depth, time pressure and then mentally calculate my SAC/RMV rates during the dive. In part it is my self check to see if I am narked. I can usually get my overall SAC/RMV rates pretty close at the end of the dive. Now with 10 dives on my Perdix AI that gives my SAC rate, I can check my...

    How long before phone-based uw cases eat the low end computers?

    Heads Up Display, HUD in the mask? With the ability to track your eyes to switch functions, gas consumption, depth time, compass etc.? How about the ability to control our camera, lights, deploy DSMB? Automatic buoyancy compensating, or use eyes to control, inflate, deflate wing BCD? Control...

    How bad of a scuba gear hoarder are you?

    I got first born male child certified. Now all the gear is at his place-and I only have one complete set with me. Although looking at new reg set and BPW setup, will need new fins and booties to go with it and dive shorts and look at that nice light...

    Typhoon Goni Super Category 5 - Luzon Trajectory

    I am in Moalboal Cebu now, no significant rain just some wind but nothing to worry about. (as of 18:00 1 Nov ) Have been talking to friends in Manduluyong City and Makati. Their local cell towers are still functional and they are reporting heavy rains and some flooding, local news saying over...

    Replace Card?

    I go with the photos on a phone. My dive log app also lets me store copies on in my app. Everything backed up to the cloud and accessible for me on any computer if I need to get it. Just in case I also have a paper print out of the cards in my suitcase along with a print out of all my...

    More weight to move from a 3mm Shorty to a 3/2 Full Wetsuit?

    Fill a bucket with water, (or tub or barrel or rinse tank or go to the pool or lake or ocean) put the suit in it and get any air bubbles out of it. Subjectively access how much force you need to put on it to make it sink. Do the same with the other suit, compare the difference. You can drop...

    requesting a dive boat discount?

    Not asking is equal to them saying no. It is just business and anyone who was insulted by my asking is someone I am not likely to do business with. Anytime I am buying multiple units of anything, especially more than the usual number of units, I will ask about volume discounts. You can make a...

    Diver patch jacket

    I am a former Scout leader and have a camp fire blanket with scouting and related badges going back to the 60's. I added a diver flay to it as well. Does that count?

    Buoyancy changes from BCD to BPW

    I dropped one kg when I stopped wearing my 2 mil shorty as a point of comparison. A full 3 mil suit, twice that??

    Unboxing a Perdix

    I am not concerned about a battery leak, just the irony of them warning you about alkaline batteries when they ship with an alkaline battery in it and they really have no idea how long it will be on the shelf before someone buys it. Moral of the story, check for batteries as soon as you buy it...

    Unboxing a Perdix

    I got a new Perdix this week. ( See my post on most expensive dive regarding flooding old DC lol) It is everything you could want. I am still exploring its capabilities and operation. When opening it there was a card inside warning that alkaline batteries could leak and cause damage. I turned...

    Deep Diving 108 feet w/ a single AL 80 (Air.) No redundancy.

    I was 40 m on a single AL80 yesterday. I bounced to 40 m then back to 30 m and gradually reduced depth to the end of the dive. Surfaced with 90 bar after 57 minutes for a 8.6 l per minute rate. My remaining time never dropped below 2 minutes and was back to 99 by the time I got back to around 15...

    Scuba a Winter Sport?

    Ice Diving is generally near the end of the winter, temps are at 0C or above and while wearing a full drysuit, usually in dark colours, with fleece under it all sealed up, on a sunny day, heat is more of a problem than cold. You want to get in the water, especially after being the rescue diver...
