The short version
The A2 Pro is a generation behind, and at 14.90 W/Th it needs sub-$0.06 power to make sense as a long-hold. Where it does make sense is curtailment-heavy sites and flare-gas installations, where the machine sits idle often enough that efficiency matters less than the number on the invoice.
- Strongest capex-per-Th figure in the catalogue
- Suited to curtailment, flare-gas and behind-the-meter sites
- Refurbished stock available in quantity

Switching targets is a firmware and pool-config change, not a hardware change. Most operators point at the top line and let a profit switcher handle the rest.
