my little virtual DIVECOMPUTER MUSEUM;
2015: Aladin ^[2], Aladin ^square

• i.e.: unpacking
• checking the error message
• switching on?
• ZAP! Nil !! nada !!! GAME OVER !!!!
• Real Quality is, when the customer returns, and not the products ....

• here we have the NDL ("No Decompression Limits") table of the Aladin [2] with L0 to L5:
• L0 up to L5 are the so-called "Micro Bubble" Levels (MB-Level)
• i.e. knobs for "conservativism", running from L0 = normal to L5 = very conservative, less micro bubbles
• so L0 is roughly comparable to the original Buehlmann ZH-86 air table (ZH for Zuerich, his home town and 86 is the year of issue)
• or the wide spread Hahn Deco2000 table
• and L5 with a many a lot more stop times (pls. cf. our notorious "TEST DIVE", further down)

• (*) is slightly varying according to ambient air pressure at sea level

• size comparison, relative: 3 generations of ALADIN

• size comparison, absolute: right COCHRAN; below POSEIDON 1000 meters

• as well you get:
• a solid wrist band, which you could lock with a thick 3-fingered-glove!
• a display protection foil
• a practical transportbox: robust and not to small:
• the back side, top down:
• battery compartment
• serial no.
• CE no.
• piezo (pressure sensor)
• contacts for the SHARC (USB cable)

• and here, the SHARC himself:
• very easy to attach,
• robust, and:
• illuminated during successful connection!

• the MENU tree is designed similar to the Aladin TEC
• as well the philosophy of operating the knob (LEFT <--> RIGHT):
• the display layout: tidy and clearly laid out

• Source: Front- and Back Side of the german Quick Reference Card UWATEC / Scubapro

• our notorious TEST DIVE (depth 42 m (i.e. 138 feet), 25 min bottom time), with:
• TTS = time-to-surface (sum of all stop times + ascent time);
• here as a small table: MB-Level first stop / time at first stop TTS --- m / min. [min.] *************************************************************** L0 9 2 40 L1 9 4 45 L2 12 2 50 L3 12 4 57 L4 15 3 65 L5 18 1 74
• so these new TTS are normally ca. 5 min longer as those from the
• ALADIN TEC 2 G
• i.e. the L_i (i = 1 --> 5) are one step beyond the old TTS!

• as well quite nice:
• the illuminated display with the big digits!
