The warmer is being used in a variety of ways.  For daily breeding:  loading guns in one location and walking to the cows, one guy straps it to his four wheeler, some work with it out of their truck or golf cart. It's being used in mobile (trailer) chutes.

It has also been used for breeding a herd of synchronized cows:  using two warmers, one guy was thawing and loading guns into a warmer, while another guy was breeding out of the other warmer.That way, when the breeder ran out of loaded guns he could swap warmers with the loader.

Some people, rather than loading a bunch of guns, are putting empty sheaths in the warmer, then dropping a thawed straw into each sheath, then putting the gun into the sheath over the straw.  This way they can carry just one gun.  We are told this technique works well as long as the straw is cut square on the bottom.

A microprocessor continuously monitors the temperature inside the unit and activates the heater as required.  The temperature is maintained at 95 degrees F, plus or minus 3 degrees (92 - 98 degF) and is very stable.  The unit does not require adjustment or calibration.  Tight tolerance components are used in the product to accomplish this.
