The D4 is due for release in 2 weeks (beginning of Feb).

Don't worry - the D4's got a good 7 hours of water time of the weekend with multiple dives to various depths to 30m so got a very good workout.

The were pre-production and beta units so there were a couple of bugs on some of the units when testing but I must stress only a couple of the very early units.

The computer isn't just a freediving computer - it's designed to cater for both the freediving and scuba markets. The scuba side of things caters for air/nitrox deco diving.

Freediving wise it has a number of depth and time alarms including a surface interval alarm which was generally very well received by all.
