The Tri Hot series putter was a 3 model series released by Odyssey in 2001.  It should not be confused with Ti-Hot or Tri Force series of putters.  They are a great putter design made of milled carbon steel with a nickel plating finish.  

The insert was the White Hot elastomer, backed by a dense tungsten weight forming the bumper of the putter.  This concept located the center of gravity towards the rear of the putter, further behind the ball than most putters at the time.  The tungsten bumper is affixed in position with small dowels and bolts, with an elastic layer between the tungsten portion and main body of the putter.  They can be disassembled and modified into quite a unique prototype putter.

A great example of what can be done with a Tri Hot can be seen at this link (the excellent work of Chris Finch Golf):

Aftermarket inserts provide the following advantages:

-Crisp response after ball contact

-A resin solution reinforced with carbon fibers, that exactly matches your putter's stock swing or a milled metal version which can add a bit of weight

-An engineered solution that is not just a plastic.
