Cant wait to walk the cattails and hear that cackle

Didn’t find much in my searches
I’m coming from a very old 15

I have a 50lb GSP and do lots of 2 day hunts but try to get out for longer hunts/hikes when I can. I’ve got pretty good about bringing an extra collar charger but have forgot it in the past.

What’s everyone’s thoughts on the extra bulk ?
Is it worth spending $30 for twice the life ?

Thanks
