the ORCA EDGE
- as well in the 80's, from June 1983, there was box from ORCA Industries available: the EDGE
- EDGE means: Electronic Dive GuidE
- the housing was made of aluminium, you could beat a hammerhead shark away with it and drop the weight-belt ...
- as well there was a battery compartment (leaky) for a 9 V block
- normally, after each dive, you had to change the battery block
- the software used a modified U.S. Navy Model with
- 12 compartments and halftimes from 5 to 480 min., nevertheless:
- if you went beyond 63, your decompression data were not very healthy, because
- it did stop the algorithm at 63!
- and just displayed depth and time ...
- it featured a graphical display for the compartment saturation and the ceiling
- it was a real interesting cinema for Mr. Mouse ...
- have a look a this nice box (for size-comparison with my TAG/HEUER Super Professional):
- these times, the so called Multi Level diving was new, so this box has been extensively tested:
- 12 volunteers had to make 10 dives within 4 days.
- the dives with doppler-detectable bubbles was virtually zero.
- so in relatively short time, 5,000 boxes were sold.
- and here we have, from 02/2012, a historical Hi-Lite:
- (all pictures made in Tauchsportcenter Esslingen)
- after precisely 25 years of dormant stay in the virtual dive computer museum
- the re-animation with the help of a new 9 V Li-Block
- the display:
- the solid line represents the saturation limit of the compartments
- according to an adapted NDL table after the USN
- (these NDL have been slightly down-sized after doppler measurements)
- and here, in a direct comparison with topical mix gas computers:
- top right the EMC-20 H from Cochran, down the NHeO3 from VR-Technology
- shortly after switching ON you will see a nice Orca:
- and, immediately following, this nice little friendly hint:
- and here the complete BOOT SEQUENCE
- as a little Mini-Video, free hand, ca. 4 MB: . . .
made in the premises of the Tauchsportcenter Esslingen
- the 15 seconds music are from the Stuttgart Jazzrock Combo: TOPICAL TEST
- and here a very interesting compilation:
