Another "YES" from me. I initially got it for my Explorer with 12" Sunray and probe mounted....it's like swinging a bus. If you are either hunting a large area with few targets where you'll be swinging awhile between digs or you're swinging something with some weight,it absolutely helps a lot! Be aware,it is made in one size and if you are any bigger than about 6'2" and weigh any more than 250 lbs it's going to be snug. If you're under these requirements be sure to spend at least 15-30 minutes fine tuning the fit,that is the most important thing. If it doesn't fit correctly it will always feel funny. It won't go over a huge heavy coat....a medium thickness sweater or just a t-shirt works well. You can hang all kinds of stuff off it if you try hard enough. It's not a cure all but it's really nice for those long wide open hunts where you do a lot of swinging. Lastly,when you adjust the bungee DONT make it too short and have to press down on your detector to get the coil on the ground. The bungee should be just about neutral with the detector hanging off it. All you should have to do is tilt the machine into the hunting position and glide it back and forth.
For ME,it's money well spent,even though I only use it around 1/4 of the times I go hunting. Good luck with your decision...
