This Kit is suitable for transporting your Nauticam or other housing with tray around either on the beach or underwater.
The longer clamps allows for more flexibility with your arm systems while the D-rings and lanyard allows for easy transport.
The Clamps are connected between 2 arms that are connected to the tray and the D-rings are connected by the lanyard.
You then carry the housing and armsystem in the lanyard. (Don't forget to tighten the clamps with D-rings when carry your system around).
Bonus - You can actually use this kit for when you are testing the buoyancy of your system - Just connect a baggage weight to the middle of the lanyard and submerse the system into water.
