Can we get a shooters bailout for this?
As to upgrading the older Kestrel 4000's, I think about $700 Billion would handle it. I could even send Pete a few bullets with that much.
Seriously, the older models, 250 data points set at 30 minutes, gives you about 5.2 days of data. I can shoot, go home, then analyze my data with the Kestrel records. If someone ever figures out a liner relationship, or any relationship, of atmospheric changes to tune changes, I'm all set!!
