1. Vemco This VR2AR Deployment Tips provides necessary information and tips to use when deploying a VR2AR Full details for all VR2AR procedures are found in the VR2AR User manual A We strongly recommend you study the full user manual before using this quick guide Weight Floatation For typical deployments we recommend using 36 68 kg 80 150 lbs weight with between 7 14 kg 15 30 Ib floatation Modifications may need to be made for deployment situations that are not typical A buoyancy of 7 14 kg is recommended to raise the VR2AR when no biofouling has occurred adjust this as needed for your deployment location conditions The floatation must be suitable for the depth at which it will be deployed In rougher conditions heavier weights and mooring Separate load lines are usually required bearing line During deployment always lift the weight section using a load bearing line separate from the VR2AR Never lift the weight in air by attaching to the VR2AR Never lift the weight in air by attaching to the VR2AR Always lift the weight using a separate Do not bump the VR2AR hydrophone or expose it to extreme temperature variations Doing so may damage the receiver and render it unable to detect transmitters load bearing line Mooring Attachment A common method used to attach a VR2AR transceiver to a mooring line is to thread the rope through one of the holes in the fl
