Also, don't forget to look at the transducer on either pack. They can be different. Both packs are fine, but if you are looking at getting a soft case, the genz pack soft case is a lot better then the pro or ultra pack soft case. The main difference is like you stated, the tackle box and rod/pole holders. however you can get an adjustible transducer arm that works with pro pack &/or cup holder. (nice when hole hopping for your coffe/hot choclate) as for the depth reader it can be put on a genz pack.
