Looks like a great idea for me.  

I bring a collapsible net like O_S does and yes it's plenty big, but I just HATE using it because of the hassle factor.  I'm very comfortable landing any big fish except a 15lb.+ pike by hand and if it gets away boatside (infrequent, but it happens) it's no big deal because I would have released it regardless.  I'm the opposite of some of you, almost the only time I do use my net is when I plan to invite a smaller fish to DINNER.  In that case, I'm taking no chances on losing the fish canoeside!!

This boga grip looks intriguing because I'd think if I owned one I could ditch the scale AND the hated net.  I'll still probably land a lot of fish by hand, but this should do nicely when I want a more secure option.
