The Redged RTH-1 Tilt Head is a simple, compact, and effective head that's ideal for monopods. Tilt is only in one dimension (forward & back), but when it's mounted on an easily rotated monopod, this is often as much versatility as you need or want.
The head allows you to position the camera for a 90° portrait orientation with the monopod in a proper upright stance – or tilt the camera forward or back without upsetting the weight balance by tilting the monopod itself.
The head's 1/4"-20 screw allows you to attach most cameras. The RTH-1 head weighs just 6.7 oz, and supports loads as heavy as 13.2 lb.
