Hott-Rod™ Rods

The Hott-Rod™ Gun Barrel Depth Gage is one of ORC Forensics’ most unique and original products.  Using one of these, an investigator can accurately determine the barrel depths of nearly any firearm without causing obstruction to the weapon.  The Hott-Rod™ is a rod, with both Fractional and Metric graduations, which requires no assembly and slides down the barrel of a gun to measure the inside length of the tube.  Anyone can scrutinize a weapon by placing it near a ruler to judge its overall length.  It takes a special tool to like this to determine precisely what is going on in the inside. 

There are three sizes of Hott-Rod™ rods to choose from, the variety of which is useful for the different firearms one might encounter, Pistol, Rifle, and Heavy Duty.  They are made to fit loosely into the various barrels so that the minimum amount of contact is made.  The end that will hit the back of the chamber is built of a tough nylon tip.  The rod itself is a slender metal cylinder jacketed in a tight plastic sleeve.  A soft rubber finger grip is placed at the holding end of the Hott-Rod™. 

Hott-Rod™ Gun Barrel Depth Gages measure both Fractional (1/16” grads) and Metric (1mm grads) reading left-to-right. 

The three size options are:
A. Pistol Rod measuring up to 6”/15.2cm length for .22 cal and larger.
B. Rifle Rod measuring up to 24”/61cm length for .22 cal to .30 cal.
C. Heavy Duty Rod measuring up to 24”/61cm length for .30 cal and larger.

Ovaltyne™ Circle Guide
At ORC Forensics we design tools for you to measure everything at a crime scene, from automobiles to fingernail clippings.  On the small end of things, we have created this see-thru Ovaltyne™ Circle Guide to easily read the diameters of little round bits of evidence like blood drops and bullet holes.  Originally part of a forensic medical kit we developed that helps measure everything on an x-ray print, we now provide these guides as individual units, sold as singles or in packages.
The two different styles of the Ovaltyne™ Circles Guides is based on the unit of measure that is standard in your work environment, either Metric or Fractional.  The Metric guide is our most popular option, which reads circle diameters in 1-millimeter increments, from 1mm to 30mm, with 1/2mm intermediate circles from 1 1/2mm to 9 1/2mm.  A basic ruler design is also printed on the top and bottom edges.  On this unit, the ruler is 15cm (1mm grads) and one edge reads left-to-right and the other reads right-to-left.  The Fractional version of this guide is incredibly similar and its increments read in 1/32” graduations (circles range from 1/32” to 1 1/4”) with a 6” rule on the top and bottom edges. 
The Ovaltyne™ Circle Guide’s functionality comes from its ability to overlay the grid onto circular or oval objects, peer through the tool, and receive accurate measurements that will not cause interference with the crime scene.  Each guide is made of .03 thick unbreakable plastic that is optically clear and features green print, which makes the numbers stand out and be readable against most backdrops.  Overall size the Ovaltyne™ Circle Guides (H x W) is 9.2cm x 16.2cm (or 3 5/8” x 6 3/8”), which makes it practical for putting in a kit or to carry around in your pocket.
