*Optional VMP-B Upgrade: The Predator 2 comes with Bühlmann ZHL-16C algorithm with Gradient Factors installed but you can upgrade it to  VPM-B with a special PIN, giving you the option of using the standard GF deco or switching to VPM-B. Once you select this option we will organised to the unlock code for your specific model and serial number. You will then need to update your firmware to the latest firmware before using the PIN code.

VPM or the Varying Permeability Model is a decompression algorithm that attempts to model the behavior of bubbles within the human body during decompression. The algorithm was initially developed by David Yount in laboratory testing and coded into Fortran by Erik Baker. Shearwater Research has implemented VPM-B according to the original Erik Baker Fortran specification. In addition to implementing the Baker model, Shearwater Research has added a new option. VPM-B dive profiles often have deep stops to control bubble formation with reduced time at shallow depths. The reduced shallow depth time can be quite aggressive with VPM-B so Shearwater Research has included a VPM-B Gradient Factor Surfacing (GFS) option. VPM-B/GFS allows VPM-B dives to be executed while ensuring that a gradient factor of 90% is never violated. Please Note: You can always purchase the VPM pin at a later date if you wish to do so. The computer already comes with the Bühlmann ZHL-16C algorithm with Gradient Factors - user adjustable conservatism.

FAQ:

How does the Petrel 2 compare to the Perdix? Why do divers buy the Petrel 2 instead of the Perdix?
Larger screen, higher profile, a more traditional 'bulkier' housing with a rugged, strong feel. EXT version also allows rebreather PP02 monitoring. You can compare the two computers by taking a look at this 2-page PDF Comparison Sheet.

Is Shearwater Research going to continue to release firmware upgrades for the Petrel 2?
Yes.  The original Petrel and Petrel 2 have the same firmware versions, and updates for either will continue to be posted in Shearwater's firmware downloads section.

What type of batteries can I use in my Petrel and what maintenance does it need?
This and other questions are answered directly by Shearwater Research in the online FAQ. Please click on Shearwater Online FAQ and select Petrel from the top menu. You can also download the current Petrel Manual. Feel free to contact us any day, we are open every day.
