Profile: Gem Mfg. provides wireless boat lift control systems. We provide remote systems, remote control transmitters and upgrade kits. Our remotes are used to control systems with one, two and four motorized lifts. We develop only remote control system designs, specifically for boat and personal water craft lifts. We also offer a floating, water resistant miniature remote control transmitter. We offer auto-stop systems that require installation of one of three limit switches. These switches depend on the type of motors.
