I have an eagle silent sixty 2, the only difference is the sixty goes to 60ft and the sixty 2 goes to 120ft. I mark the tiniest jigs in 40ft of water.... One color is a little hard to tell the size of the fish but after a little time using it you can tell the bigger fish from the smaller ones. Staring at the screen long enough I can even tell the species that the orange mark is. It marks depth as well as any modern entry level unit but a little bit harder to tell bottom composition. Also my unit likes to fog up on the inside of the screen outside the hut in extreme cold temps. Plus be prepared there is no IR setting so if there is anybody within 40 ft of you, you will for sure have a hard time, but again after long hours using it, you will still be able to tell what is going on if your are fishing next to your buddies with vex's... One guy really hates me.... lol my silent 60 2 jacks up his lowrance open water sonar something fierce!!!!!
