I will be sticking with my Shockwave. I went down the caller rabbit hole a few years ago. After trying multiple callers I discovered that it was more technique and experience than equipment that equated to success.
Tried the following:
Primos Alpha Dogg

ros best responding remote that worked without line of sight and cool functions, cons sound distortion at high volumes, cumbersome legs. Gifted to a friend (best overall for the money) should have kept this one and settled, hindsight is 20/20.
Fp wildfire: pros love the small size, cons short battery life, terrible remote.
Js Grimm speaker 2: Cheap and got the job done. Nothing exceptional. Gifted to a friend
Flextone flx500: new in box never used
Flextone flx50 handheld: good for roadside locating. Gifted to a friend
Fp Shockwave: pros: foxpro customer support, tx1000 baro sensor, moon phase, Great sound and uses same batteries in remote and caller. Cons: large size that is cumbersome to carry long distances and speaker angle has to be setup on each stand, floppy speakers that are noisey to put in transport position, line of sight remote that sometimes needs several attempts on buttons to get a response. Probably should have bought the fusion for smaller form factor?
A modified patriot with a tx1000 remote with non line of sight and twice the batteries would be my dream caller. Or possibly I could get a hellcat and grind/chop off all the sharp edges that will collect dirt and snow.
Maybe I should find an old Primos turbo Dogg? Try an icotec hellion+?
Basically what I am trying to say is no caller is perfect and you can spent fortunes chasing a dream. Find one that works and stick with it or clever marketing will get all of your money.
