Fair enough mate if your happy with it - stick with it, me I couldn't be stuffed mucking around doing all that, I need something that is portable and easy to put in my pack, as for the features the Fox Pro has - well there's isn't anything on the market today that even comes close.
I've seen em in action and I can tell you they definitely work and work very well.
Good luck with yours mate, I hope it works out ok for you - I guess if she doesn't you can always go the Fox Pro.
