WAIV XStream Installs in a minutes. Just stick it on. No wires to connect. WAIV XStream: Easy to Use by Design "Ease of installation, ease of use, and affordability are top priorities for WAIV," said Magnus Berggren, president at WAIV Technologies. The WAIV XStream is perfect for rental businesses that hire seasonal staff of various technical skill levels. With WAIV, staff do not need to be marine electricians. Improper electrical installation frequently causes battery short-circuiting that may strand renters at sea or make a boat unavailable to rent". We're also really excited to introduce two-way communication, giving renters the ability to request assistance, or request additional rental hours, providing upsell opportunities for rental companies."
