From RAWalker:

I’m not a fan of Sunnto. I’ve found them to be more conservative then necessary. I use wireless air integrated computers and I don’t like the way that Sunnto’s models sync.

On the other hand I do like the way Oceanic wireless computers require you to preprogram the transmitter’s serial number into the PDC. It eliminates the problems of the Sunnto system.

Most of Oceanic’s models have a conservative setting you can program if you should need it. This should be considered by those that a leaning towards the Sunnto because they have heard it is more conservative. I prefer not being required to be more conservative with Oceanic models it is my choice.

Cost and sales model should also be considered. I choose not the purchase from manufacturers that require a MARP sales agreement from their dealers. MARP requires dealers not to sell below the Manufacturer Approved Retail Price. Sunnto is a MARP company and as such if you purchase below the MARP price usually from an Unauthorized Dealer you may loose warranty coverage.

Oceanic is a MAP company. MAP requires dealers to not advertize prices below the MSRP but allows dealers to discount as they see fit. As long as you purchase from an authorized dealer you retain the factory warranty.

Between my wife and I we own 4 Oceanic PDC and they all work great. We have 2 Atom 2.0, a VT Pro and a VT3. I have also had Atom 1.0 models and except for short battery life no problem on those either.
