Oh boy, I have so much to say about this sight mostly good some bad. I owned one for awhile and returned it as it wasn't for me as i like to shoot from 20yds out to 140yds and I couldn't get it to work for me at those distances.
A lot of people complain about the setup on the sight, but to be honest i found it super easy once i read the instructions. All the setup videos are confusing, what i wish they had though was micro adjust on the rest for aligning the rf/aiming ports, that can be a pain in the butt, same as a non micro adjust on arrow rest.
Once set up (took me about 20 mins before I started calibrating), strongly suggest you measure your current height of your sight pins from an arrow/distance from riser etc, so you can pick the right mounting holes and where it should sit on your bow to be close. Calibration is super easy as well (its ideal to have a tuned bow fyi), you start plinking arrows at various ranges and adjusting the pin if it was high/low/left.right, it will ask and by how much. take your time here and get it right as it will affect your setup of the pins.
I was hoping to be able to get out to 120-130 yds with the sight and if I could have I would still have it. I practice from 20 -140 yds on the regular, so that was important to me. I probably could have but i like my arrows in the 500-600 grain range. believe my max range was 83 yds with the sight. I could get this to 96 by adjusting the stack(pins) up in the sight and recalibrating the aiming reticle to a further distance then 20 yds. but that made the short range pins high up in the sight which I am not a fan of as I found it hard to aim with a pin at the very top of the sight window.
The ability to store multiple arrow profiles i liked, but not sure I would use that feature again as i really only shoot one type of arrow at a time and my bow is tuned for that specific setup.
Aa for the cons, well besides the long range for me/cost, there was none that really stood out. I quite like the idea and concept and think Garmin hit it out of the park. Wish they were not so darn expensive to be honest. Loooking forward to where these sights go and the features that will come out on them.
Couple of items I would like to see them address:
-better angle compensation/cuts when shooting at steep grades
-ability to have the ability to flick btw two calibrated distances for the rg/reticle alignment. so then you could have pins for shorter and longer ranges on the same screen. say sub 50 you flick the switch to position one which is set at 20 yd alignment and you get your pines from 20-70, position two is set to like 60 yds and you get from 50-100/etc
