The integration of sonar, GPS and digital mapping is an untouchable trifecta of technologies that help anglers catch more fish. And today there are a lot of “good” units on the market that will do just that.
This perch was caught in Lake Webster in Indiana...summer of 2005! This is my biggest perch to date! Unfortunately, I didn't have a ruler so I grabbed the nearest object...my cigarette case which measures 7-1/2" long! Hoping for a bigger one next year!
