Hi Janice,
At the start of the year, Decimator Design started using a completely new manufacturing facility with some of the most advanced manufacturing equipment available. This has vastly improved the manufacturing quality of the products and could potentially solve the issues you’re having with your older units. If you open a support case using the link in my previous post, we can have them back, test for issues and sort it out for you.
With regards to the power, the power protection was improved around 2 years ago, so it depends when you bought your unit. Although the Decimator 2 is a great application for the Steadicam, it wasn’t originally designed for that particular use, so it was designed for max 24V DC power.
The new Decimator products (MD-HX, MD-CROSS) all have a max tolerance of 32V DC. Any new products going forward will have the same power tolerance.
