Revolutionary March 1:10 Ratio Zooms Amaze Optics Experts
March pulled off a major coup at SHOT Show. The new March 1-10×35mm and 2.5-25×42mm zooms were the talk of the Show. This is the first time ANY major manufacturer has been able to achieve a 10 times zoom ratio. March’s booth was mobbed as engineers from other optics companies came to see how March “achieved the impossible”. And the optics guys had to fight past a line-up of military personnel — from the USA, Canada, Israel, and Germany. Lou Murdica was there and he reports: “Once word of these scopes hit the show’s Tactical area, March had more military and law enforcement people from the U.S. and other countries than you could imagine.”

Apparently, the U.S. Military has been asking domestic manufacturers to perfect a 1-10X zoom for years, and the response was always: “It can’t be done.” Well, starting from a blank page, the engineers at Japans’ DEON Optical Design Corp. (makers of the March), figured it out. For the military this is a HUGE technical breakthrough because a 1-power optic is ideal for close quarters combat (or house-clearing) while 10-power is a good setting for long-range sniper work. The two 1:10 ratio zooms both feature 1/4 MOA clicks, illuminated plex or MTR2 reticles, 30mm tubes, and a huge elevation range: 180 MOA for the 1-10×35 and 100 MOA for the 2.5-25×42. Both these scopes are slated for June 2009 deliveries. The 1-10×35 scope is expected to sell for $1500.00 while the 2.4-25×42 will cost about $2400.00
