Thank you for your answers. I was able to down load a manual and additional info to improve the unit. I had no idea how much that unit could do. I sold it with the new manual on a disc and made enough to pay for my new color finder for the bow. Thanks again…TJ

Thanks for the quick reply. I removed the unit and installed a color unit for better visibility. Would upgrading the version make the unit better for whoever buys it. It works great ,it was just to hard for my old eyes to see.
