I got really lucky this year. I've had a Perdix for a couple of years and love it. Right at the point where my tech training and diving was increasing, and I was considering a second tech computer to 'back up' the Perdix, two things happened: my company had a great year and shared that in a great bonus, and about one day later Shearwater announced the Teric. After one dive, the Perdix became the backup to the Teric.
