We make the revolutionary PAS-Thru BoxTM

The Smart way to interface
all your marine electronics!

Interface electronics easily and professionally to keep your wiring organized yet always ready to accept new device wiring into the future!

Want an existing GPS interfaced to a new large-screen plotter and to a VHF for DSC distress calling and more? Significantly reduce installation time with the PAS-Thru Box™! Does your current setup look like a bundle of electrical tape and wire or something you never want to touch again for as long as you own your boat? Now you can get that new Chartplotter or VHF radio with Class D DSC or any other device you've been eyeing in the store and know that it can be easily interfaced to the rest of your equipment in just a few minutes!!

Available in two sizes plus internal system flexibility and expandability combine to provide a solution for virtually any low-voltage interfacing need. You can also easily upgrade to the larger model as needed!

The included Wire Planning Guide makes planning your complete interface solution easy and concise, plus you can plan your interfacing in the comfort of your home or shop and not behind a cramped helm. A spreadsheet template available on this website gives your project that extra level of organization and polish and, if you're in the installation business, makes your regular projects extremely easy to complete.

Take the completed Wire Planning Guide to the vessel and route the interface cables from each device to the PAS-Thru Box™, labeling each using the provided cable ID labels. Then, in just a fraction of the time needed for the old way of connecting all the wires, you will have completed all interface wiring professionally and reliably while maintaining full adaptability for future interfacing needs.
