Any lowrance is gonna be the exact same, all are 20 degree with mostly the same power output. I have found both by elite 7 ti and elite 4 chirp have been inadequate with small jigs over 20-24 feet, cant see em too easy. That being said, it picks up larger jigs, and spoons just fine. It works, but it becomes very easy to lose your jig when fish come in, due to the computer trying to eliminate small echos. That being said, that was more a problem with the elite 4, not the 7ti. What unit size specifically are you looking at?
