    Ideal diving conditions for new divers?

    - comfortable temperature - good visibility - slowly declining seabed - easy access for getting in and out - no, or little, current - good safety infrastructure, or easy access for emergency services .... Usually you can't have it all, but some places are better than others

    Wow, doubles really are easier to dive than singles

    Indeed for balance reasons (but also for total air supply) they are a definite improvement; how much depends however if you have been diving with a BCD or a BP/W before. If you are diving with a BCD and a single bottle all of your balance depends on how the jacket is adapted for the body; ie...

    Summer 2015 trip to Italy

    There are lots of nice places to visit. You might want to start with the Cinque Terre region, even so it is north of Florence. The villages (especially the more southern) are nice to visit as a tourist and might want offer the opportunity for a first dive (I dove about 4-5 years ago there in...

    What are the three biggest issues you have with diving?

    All the time that I am not in the water (driving to the site, driving to get a refill, etc.)

    Doubles with isolation open or closed Lesson Learned

    In your post (both initial and the one above) you mention TIME left, rather than usable gas. How do you estimate time (and time difference left), if not based on the remaining volume of gas and your current/standard air consumption (sac)? If you base your "time left" on the expected time left...

    Din or Yoke

    +1 for DIN When i started diving, yoke was the standard. So a number of my older first stages are still yoke. More recent regs are DIN, because it is safer and allows for 300bar Whenever I went abroad using either or was not an issue. Most of the time when using DIN, by having the inlets...

    Question About Online Gear Retailer

    I have ordered a few times gear at DiveInn and it always worked out smoothly. Never had an issue that an item which was not in stock, unless marked so. Thus I can recommend it. Obviously not all stuff should be bought through internetshops, but this is a more general comment. Living in...

    Why do we breathe more at depth?

    Hi Qasar, Yes, the regulators provide you with gaspressure equivalent to ambient pressure, otherwise your lungs wouldn't be able to take it in. A nice exercise that I do occasionally with my students is to give them an extended tuba (about 1.5m long), allowing them to use it at a depth of 1m...

    Diving Deutschland!

    Hey ladies & guys, I might want to join on your discussion and support the idea for a sub- forum for Germany. While I never dove in Germany, I know a number of places in Belgium, Luxemburg and the Netherlands (und spreche natürlich auch deutsch) In all of those countries you can also find an...

    UK light canon eled performance?

    I am using a dual GreenForce setup, which allows me to use both a HID150 and a TriStar (3 LEDs). The initial reasons for this choice were strong light (HID), temperature of the ligh (HID, and a bit in the LED), battery autonomy (both), heat issue outside of the water (LED), resistance to shock...

    How do you stay warm on a dive?

    Wetsuits: While being younger I dove with a 7mm neoprene wetsuit and 5mm hooded vest down to the low 40s F. Both in summer and winter I put a thin surfboard nylon dress - basically I bought it for easying to put on the wetsuit, but in winter it also helps for keeping the warmth, as water is...

    is there anything missing from the dive industry?

    Some things I could think about: - dive computer with GPS receiver. Won't obviously work in the water, but could record positions when starting dive (dive location, main purpose) and eventually when getting back to the surface (drift dive). - (cheap) boeys with sonar sound. Purpose for lakes...

    Petrel reading depth wrong?

    You state that it is set for saltwater. Does this only apply to the Petrel or also to the Oceanic (I am not familiar wit the possibilities of the settings for the Oceanic)? If the Oceanic is set for fresh water, then the different density of salt water would explain why the Petrel, when set to...

    Weighting with Backplate/Wings and Drysuit

    To make it short: since I am using a BP/w (ScubaPro with steel backplate) I am no longer a belt (and haven't added weights elsewhere) ... well not exactly, in the cold winter months I am adding 2kg for being able to add more air in the drysuit. So, to the OP: - when changing from a BCD to a...

    How do you bag your BP/w Dive equipment

    I am not sure that everybody is dismanteling the BP/w everytime they go to a diveplace. My reading is that most do it when going for air travel. Regarding the packing of my box/container: it is packed in the reverse order of putting the gear on (i.e. hood and gloves in the bottom, suit in the...

    How do you bag your BP/w Dive equipment

    I have one box with everything (wet or drysuit&undergarnment, hood, gloves, boots, regulators, mask, snorkel, ...) and a bag with the lamps&computers; the fins, the tank(s) and the BP/w are put extra. For transport by car/boat this brings the number of items down to something that can easily...

    Deco Cylinder for SM100 - What is your opinion?

    Regarding EAN testing, stick at minimum to the local regulations for testing ( LDS might refuse to refill cylinders that don't comply), but in any case have regular tests done.

    Question about gloves...

    Buy what gives you the best comfort and feel free to mix brands. Depending on the region you are diving, you will want the gloves and hood to offer better thermal protection. PS: if your wetsuit "offers" special features ( f.i. Semi-dry), then you might need to buy gloves/hood adapted to these...

    how much weight do I need?

    When I took my classes, everybody was to have their own weight belt (and weights) - and this still so. Considering the price of the two, I don't see a reason why not. The only mpents for me to rent wre when I take the plane to go on a trip. So, as to answer the question of the initial poster...
