PM4 vs PM5 plus ipad

[Marly]

Hi all, Just bought a C2 with a PM4. I’m primarily a runner, not a rower, and I’m completely new to C2. My goal is to use the C2 for fitness/cross training during covid and beyond. I’d like to use apps like Regatta to make rowing more interesting during our upcoming winter. Wondering if I need to upgrade to a PM5 or if I’m okay with an iPad and a PM4. I will also wear a fitness tracker (garmin or Fitbit Or Apple Watch) that can record heart rate and such. I know the C2 community has a lot of avid rowers, and I could be convinced to get more serious re stats and such, but starting out as someone looking to have some fun while staying fit.

Congratulations on purchasing the best rowing machine
I used to have a static linked to PM3 and rowpro
Main difference is PM5 has ant and Bluetooth : latter allows ergdata to link wireless y to iphone/ipad/Android ergdata
Rowpro and computer require cable
There is a cable to link PM4 to phone for ergdata
Also PM5 uses flywheel energy to power screen when rowing so longer battery life
Personally I would save money and buy rowpro but others may differ
Best wishes Adrian

The cost of the lightning to USB-B cable will be more than selling the PM4 (on an auction site) and buying a PM5 (which connects with BTLE).
