Bushnell Golf- Phantom 2 GPS https://www.amazon.com/dp/B095J1RNXG/ref=cm_sw_r_apan_glt_fabc_T9GQTFP329AJ4CPNJJ79?psc=1
It gives you front middle back, hazards, bunkers, a yardage shot tracker, score tracker, etc, on the device. There's also the Bushnell companion app that syncs to your phone via Bluetooth and gives you visual layouts, score card, and some other stuff I don't use. Incredibly accurate to the inch.
I use an older version of the Bushnell phantom. Cheaper / less time consuming than a good range finder. Gives me a quick front middle back number. Helped me greatly. My only complaint is the battery seems to drain even when you turn it off so you have to be really on top of keeping it charged. I’m sure the newer versions have improved this.
