Hi
@PerthPom
A slightly different take.
In the US, the Peregrine goes for $550, your price of about $500 is a small savings. The Peregrine TX alone goes for $700. The Swift transmitter goes for $400. The bundle of the Peregrine TX and Swift saves you $100 at $1000.
In the US, the bundle of the Geo Air and transmitter goes for $800, a $150 savings over the computer, $550 and the transmitter, $400 alone. The price you quote for the bundle of $500 is a very significant savings.
With the Geo Air, you would have an AI computer. The MH8A transmitter is compatible with all the Shearwater computers for a future upgrade. Oceanic/Huish will replace the transmitter for $120 no matter how far out of warranty it is. The computer runs DSAT, approximately a GF high of 95 and PZ+, approximately a GF high of 85. Both also have a conservative factor if desired. Neither the Geo Air nor the Peregrine have a compass.
Good luck in your computer purchase
