It's a great computer, but it is definitely overkill for a rec diver, and I say that as a rec diver who has 2 Perdixes (Perdi?) in the house, one for me, one for Mr. OOO. Do you
need something that fancy and expensive? Probably not, but it is a great rec diving (and tech diving, if you ever go down that route) computer
if you decide that it is within your budget and you are okay spending that kind of money. You won't outgrow it.
I’m curious is their anything else close to it?Do you know if the Teric outperforms the perdrix ?
I wouldn't consider the price difference in the decision.
Something to keep in mind with the Teric vs the Perdix, apart from the different form factor/size, are charging and the running costs. You do need to remember to charge the Teric. Should the batteries on the Teric completely die, you will lose tissue data. As it is a lithium battery, after many charges and discharges, the useful life and capacity of the battery will decrease. After a number of years (Shearwater estimates about 5 under normal use), you will need to have it replaced and it is not user replaceable. It's about $100 CAD + shipping to do this.
For a Perdix, you don't need to worry about charging it and any AA form battery will work. You will get 40-80 hours of dive time (approximately) depending on which battery you use. All batteries are user replaceable. You will not lose tissue data when a new battery is being put in and it is also safe to do this during repetitive diving.
It is purely personal preference. Choose the one that works for you.
