Hi, I'm looking to buy an OSTC dive computer but I'm undecided on which one.

What is the difference between the 2 and 3? What type of divers are they targeted at?

Thanks

The biggest difference is size / form factor, the OSTC3 has user replaceable battery and can connect to a rebreather to monitor the cells via the optical link cable.
