I'm here to help you find the hand control you're looking for regarding your OVHD setup! While I couldn't find a specific hand control for OVHD, I did find some great remote control options that might be useful for your setup. For instance, the Wireless Remote Control Water Level Automatic Control System could help if your task involves keeping things automated and tidy, priced at R1250. If you're looking for something more related to audio or TV, the Car Audio System with a 7-inch Dual Spindle LCD Touch Screen Stereo Radio is a fantastic choice for R894, giving you multimedia capabilities. If you're open to exploring different products, the Motorcycle Throttle Grip could be a fun addition for any vehicle control setup, available for just R54. If none of these hit the mark, I apologize as I might not have full access to the entire PriceCheck catalog just yet. Let me know if there's anything else you'd like to explore!
