Visitors to the Conklin & de Decker display (Booth No. 3323) during Heli-Expo’09 can receive a 20-percent discount on some of the company’s most popular products, including the Aircraft Cost Evaluator, the Aircraft Performance Comparator, Life Cycle Cost and the State Tax Guide for General Aviation. The Massachusetts-based company released the 2009 tax guide earlier this month.

Conklin & de Decker representatives are providing free demonstrations of the products. In addition, visitors have a chance to win a Garmin Nuvi 760 automotive GPS.
