For orders that can ship complete from one warehouse, Today is extended to 1:30 PM for Oregon, 1:00 PM for New Mexico, and 11:30 AM for Utah. If you click the link to Show all four warehouse quantities, you can see exactly how many items can ship from each warehouse.
The Probe Unit was just a testing tool to see what kind of results I could get. My original plan might still work but it will take some effort to apply the calibration information (which could be done after the Nano Logger collects all the raw data).
Probes are always provided with the gun in the purchase price. 2. Collars - these are units that look and work just like the ones we use to fill our car's tires. They have collars which pull back and then attach to the male charging unit on the gun's air tank and lock in place when the collar is released.
