Coldbore Program from Patagonia

Main Features:

It is made up of 5 (five) Modules, designed and programmed to be fully compliant with the guidelines of a Microsoft® Windows-based application.

1. ColdBore© Desktop edition allows the user to generate Reports ( Print / Preview ) or Export to MS Excel most of the generated output, according to each Module function. (Desktop edition only)

2. Several and inter mixable unit’s system. Choose between metric or English, or mix them, no problem!

3. Installation & User’s Manual in PDF format for easy access.

4. Share your data with others using our XPS and PDF-based reports or Excel outputs. Just print or send any created report by email using your browser built-in capability.

5. Data synch with Mobile device

Here are my thoughts so far, I am really impressed with how closely the program runs with the actual results I am seeing in the field. Here is what I think gives it an edge over some of the other programs that I have used before:

  • It links through Bluetooth to my Kestrel unit and streams live environmental conditions to your ballistic program
  • It stores your zeroing environmental data as a baseline
  • It has GPS functions which allow you to store target information on ranges you regularly shoot at (if the target stays in the same spot, it will also account for small deviations in your actual shooting position) This will be nice for shooting on “square ranges” where the targets are frequently in the same position and you may or may not be at a static firing line.
  • It has a built in camera
  • The Nomad runs a windows mobile software that can be synched with laptop, data entry can be done on a laptop or on the unit whichever is more convenient or possible at the time and then the two programs synched at a later time.
  • When using the laptop version it is easy to “pre-plan” for a hunting trip, for example if you have access to elevation and topos of the area you can print out range cards for multiple weapons if hunting as a group to add to your data book.
  • You can sit down once you reach your firing position (I often hunt this way, hike in and set up camp on a “high spot” and look for long range opportunities) Fire up the unit and check against the range cards you have prepared to see if the current conditions are making any significant changes in your predicted drops at known landmarks in the area.
  • It has a module with pictures of different target varieties that you can mark your impacts (including group sizes) It also allows for downloading actual pictures of targets, giving you the ability to keep your data very detailed and accessible in a compact unit.

The only fault that I have found up to this point is that once the program is started and information is streamed from my Kestrel 4500 to the unit/Coldbore program and system is utilized. If I exit out of the program, the only way I am able to reconnect to the Kestrel is to do a “Hard Reboot” on the Nomad in order to reconnect to the Kestrel. It is not very field expedient in that manner, though I will say that although I see this as a fault, most times that I am using the unit, I enter the program and retrieve the data that I need and then shut the Nomad down until I need it again, so though it would be more user friendly if you could enter and exit the program at will, it does not appear to be a major hindrance in my normal use of the system.

I am anxious to test the unit in a variety of different environmental conditions and see how well it tracks as far as giving you the best prediction for a “cold bore” impact at distance. Up to this point I am very impressed and excited about the possibilities that this unit provides. This along with my Vectronix Terrapin, and .375 Cheytac, I hope will prove to be a very deadly combination in the mountains in Nevada and Montana this fall!
