![]() ![]() The new Dives panel has 5 different tabs: Mac users will recognize the model that Dive Log DT uses to display your diving logbook information.You can create and view information about your Dives, Buddies, Locations, Types of Dives, Equipment, Personal Information and Certifications (including photos), Shops, and Trips. Really, it's so easy to do.ĭive Log DT is a completely new application. If you are in a place without public WiFi (like maybe on a boat in the ocean!), you can still sync by setting up a WiFi between your 2 devices. Later, when you have your MacOS machine available, you can use Dive Log DT to *merge* the additional dive computer information into the entries you have already created! Just transfer your logbook from the iOS device to the desktop, merge or add the new information in, and then transfer the logbook back to your mobile!. You can take your iDevice to the dive site with you, enter all the information about the dive including photos and GPS information and log the dive as much as you can while there and while the information is fresh and your buddy can sign your log. We designed Dive Log DT to work hand in hand with Dive Log for iOS. We also have a sample logbook file you can download and play around with to gather more information - take a look here to try it out! If you have any problems with the software, please contact More Mobile Software support directly and we will do our best to make you happy! Also check our forums for more information posted directly by our existing customers. Many new features were added for the current version 4.3.0! ![]() See our screen shots below for more information about it's features and visit the Mac App Store to purchase and download. You can then synchronize your log back to your mobile device using Dive Log on iOS. Dive Log DT extends the free Dive Log Manager application to allow editing directly on your desktop and to directly download selected dive computers (see below for the exact list). The purple and red bubbles each have a density that is lower than the surrounding water, so they float at the very top of the thermometer.Dive Log DT is a new desktop application found on the Mac App Store that is designed to allow you to edit and manage your digital scuba diving logbook. The blue and yellow bubbles (60 and 65 degrees, respectively) are calibrated so that they have higher densities than the water at this temperature, so they sink. ![]() Since the surrounding air is 70 degrees, we know the water inside the thermometer is also about 70 degrees. Now, let's say the temperature in the room is 70 degrees. The blue bubble (60 degrees) is the heaviest (densest) bubble, and each bubble thereafter is slightly lighter, with the red bubble being the lightest. Let's say there are five bubbles in the thermometer:Ī yellow bubble that represents 65 degreesĪ green bubble that represents 70 degreesĪ purple bubble that represents 75 degrees The bubble that sinks the most indicates the approximate current temperature. So, at any given density, some of the bubbles will float and others will sink. As the temperature of the water changes, it either expands or contracts, thereby changing its density. The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. It is the downward force of gravity that makes this thermometer work. If you have read this question, then you know that an object immersed in a fluid experiences two major forces: the downward pull of gravity and the upward push of buoyancy. So, after the weighted tags are attached to the bubbles,each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water. The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. Since the bubbles are all hand-blown glass, they aren't exactly the same size and shape. The weight of each tag is slightly different from the others. These metal tags are actually calibrated counterweights. A number and degree symbol are engraved in the tag. This liquid mixture may contain alcohol, or it might simply be water with food coloring.Īttached to each bubble is a little metal tag that indicates a temperature. The bubbles are glass spheres filled with a colored liquid mixture. The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles. A simple, fairly accurate thermometer, today it is mostly used as decoration. Based on a thermoscope invented by Galileo Galilei in the early 1600s, the thermometer on your co-worker's desk is called a Galileo thermometer.
