I just installed the ADM Dual GPDX saddle on my Explore Scientific Exos2GT Pmc8 mount. It’s a worthy upgrade for my mount my scope is much more secure than the stock saddle which has two bolts that press into the scope dovetail. The ADM Dual has a dovetail rail that grips the whole scope dovetail without scratching the paint. Installation was simple, the fit and finish are amazing.
