I have been using Scott Archery releases for several years now. I particularly like the Scott Rhino for hunting as it takes nothing but feel to hook it into the string loop. The trigger tension being adjustable, and the fact that you can adjust the length of the release is a big plus. mechanically they are totally solid and give a very comfortable feel during the release.
Releases are an individual preference. I tried several before I found one I like and I'm sure if I was to continue to try. I would probably find some others that work for me. As of now and for the last few years. I've been using a Tru fire Hurricane. It has an adjustable buckle and a very smooth caliper release.
I've been using the Trophy Hunter for years with good success. It's small and not as bulky as some others. As mentioned it's personal preference. Try before you buy. Some are more comfortable then others and some are better suited for hunting rather then just taget shooting.
Ive been using the Scott Mongoose for years. Never had a failure yet with it...Have hunted in temps as low as 40 below with no freezeups. Smooth...Adjustable trigger and head length for comfort. They have many design models. If its for hunting I wouldnt recommend the Back tension release styles untill you are VERY used to one. Stick to either the dual or single caliper style. As the others have said, its a choice of what fits you and your shooting style. Scott Release aids are top of the line and do cost a little more than some...But you get what you pay for and with them you are getting a High quality product with the Archer in mind
As I sit and glass, which is common for hunters out west, I have sort of quickly discovered something I never learned when I was younger.
In my youth I had enthusiasm and spirit. In my middle to advancing years I have creaky knees, arthritis, and I tire more easily than I used to. Where I used to sit on the cold hard ground I now look for that soft spot to sooth my tired muscles. That leads me to my tip.
Carry your soft spot with you!
In my pack I carry an air filled, ultralight, camping pad....
