May we strongly suggest that you review all of the information provided on our web site prior to giving us a phone call or sending an email. The response (information you are looking for) you will likely receive is (more than likely) already posted there in an easy to understand format. It will save you a significant amount of time doing research and it provides valuable information you may not have even known or considered. The website was developed based on the questions we received over the years on a daily basis. We are always adding new, beneficial, and unique questions and scenarios. Many have referred to it as a great free online resource (book). The Product pull-down menus are not just a sales tool. These sub-menus provide valuable information to aid you as you decide on a solution. The FAQs are a MUST READ - especially if this is your first time to the ZRD website. The FAQ section will greatly assist you with your endeavors. It provides clear details on what to do and what to avoid. If you glance over or skip any of these areas, you may miss an important piece of information that could be critical to a safe, reliable, and useful electrical system. To aid in your decision making, a number of myths and outdated technologies are exposed. FAQs-5 and Company pull-down menus provide information regarding ZRD that may be very helpful. The Links pull-down menu has many extremely valuable resources for you to use at no-cost. Our website is designed for what we would like to find when we are doing our research and investigations. It is for the thoughtful, analytic, consumer.

Similar extensive system designs have been provided to US and International customers located around the globe - Europe, South Africa, Australia, SE Asia, South America, Caribbean, & others.

Regarding pricing, review the Do Homework First link (under FAQs-5). We provide the most cost efficient pricing available; however, we truly desire to support our end users, unlike the vast majority out there. Discount outlets do not provide any. If all you desire is price, you will probably be on your own to succeed or fail with their lack of knowledge, expertise, and desire to provide support. We assist our customers according to their needs and desires. Experience has shown us that even the best require a small amount of support at some point. We are always there to provide whatever you may need.

TOOLS (under Links) should not be missed. There are many, often overlooked, items of significant importance to every sailor available.
