I am new to PWC fishing and recently purchased the Fathom 4 to carry on the back of my Fish Pro Trophy. I had been trying to decide between Opah Gear or another manufacturer. After reading the reviews, the insulation thickness and the fact Opah is handmade, I was sold on Opah. When I received my Fathom 4 I was absolutely blown away at the quality. This is a very well made kill bag! Between the insulation, the drain plug, and the heavy duty carry handles this thing is an absolute beast. I am sure this bag will last me quite a while.
