Actually had our first hunt using a dialup for longer shots a couple years ago. My son, an Army Sniper just off active duty was the hunter/shooter. We were glassing country from 100 yards to 1500 yards away. When we spotted a buck I got on the LRF (we all have those now because I would be the last likely to buy such a gadget) and he got his rifle up. I lased the range and referred a drop card I made up the morning before before with a phone APP ( we all have phones too so all it cost was $20 or less for the Strelok Pro). I give him dial-ups and he tracks the buck and I tell him that the next opening is his best opportunity and I reconfirm range for his likely shot. Buck pauses in the opening, boom buck stagers down hill and drops. For long range shooting I believe a fellow hunter or dedicated spotter is essential. They can run a laser get range feed you the dial up and do it quickly and very precisely also a spotter is near a must have for after the shot. When you shoot with any caliber with umph you are not going to see your hit and the afterward. That and hiking 800 yards or so to where you think your quarry pilled up can be difficult with any kind of cover. Try crossing a drainage and heading uphill and realizing all the clumps of trees, brush or rock outcroppings you are sure your deer is under now all look the same. A spotter to guide you in is nice almost as nice as the range and dial-ups he gives you. Yes you can range with a MIL or even an MOA scope but LRF and current drops from an app are fast and precise.What is the angle of your intended target up or down from you ? I'm with Retiredsniper and Uncle yib get a good second focal plane scope with a mil retical, study on using it to range and hold for wind quartering , full force . It takes time in the field with the equipment you plan to use to get proficient with it . Once you have gotten proficient with this then you will have saved your money for all the other things that are nice to have .
