Hi all, I'm new-ish to steadicam, done the bronze workshop and a few shoots with a hired rig. Recently I picked up my first rig, an ex-rental Zephyr. Generally the package is in good order. The monitor is a bit intermittent with the SDI signal, predominantly it just drops out briefly but sometimes the colour go a funky two tone. I've bypassed the post to eliminate that as a cause. Would be grateful for some advice on the following. Is it worth repairing the standard Zephyr monitor or do most people upgrade it eventually? If no, what monitor should I be considering? I have a Small HD 503 which I love but It's probably too small for the sled What other upgrades to the sled should I consider? got my eye on a monitor yoke and a 24v battery option. Many thanks
