Here is the breakdown on the liquivision models coming out soon:
Liquivision F1 (0-160m): $395
Liquivision F2 (0-330m): $495
(The F1 includes the PC interface, and wall charger)
F1 Solar Charger: $50
Liquivision S1 (0-100m): $155-$175 (TBA)
(does not include a PC interface)
S1 PC Interface: $50
S1 Solar Charger: $50
The F1 has a 128x64 graphic OLED display (yellow pixels on black background), the S1 has a 8x2 character LCD, yellow characters on black background. The S1 is slightly bulkier.
Both show time/depth & current velocity, ascent/descent splits & peak velocity. The F1 has an extremely accurate temperature sensor (within 0.25C), and also a salinity sensor. So the depth measurement on the F1 is temperature and salinity compensated. The S1 depth measurement is not as accurate. Both watches have alarms of > 98dB, but the S1 alarms cannot be activated unless you have the computer interface.
Neither computer has a stopwatch, and neither computer has any buttons. This way you don't have to struggle to get buttons to work which never seem to work properly anyway.
These will be available on:

The F1 has user reprogrammable software. This means it can be used as a programmable 'dive slate,' to display various messages to you at set points on the dive. The F1 will come in an optional mask/head mount version, since it is so small. That way, it will always be visible. After the turn-around, you could program the watch to show 'Go Fred! Kick hard!' Then, nearing the halfway point of the ascent, you could have programmed it to say 'Fred, nearly halfway there, speed up!' etc...
Alternatively, a salvage scuba diver that has complicated tasks to do, could have the computer cycle through a reminder list of tasks, etc...
