[CA] [CA11] e7D Fishfinder Upgrade Questions- New User

[MB19565]

This summer I purchased a 2013 Center Console boat equipped with a Raymarine e7d and a P58 Transom Mounted Transducer. Overall I found the unit to be user friendly and easily upgraded to the newest version of software.

I Live in Coastal NH and fish for striped bass. Fishing depths range from 4-60 feet. I feel that the fishfinding functionality of the e7d has been good- but I would not classify it as great. I would like to see more definition and a greater ability to differentiate fish form bottom debris. I was never really able to get that signature curved marking of fish that you see on many units. Full disclosure this could be my inexperience with fishfinders and might be a setting issue? See attached picture- in this case I couldn't tell if these were fish or debris in the water. I have not played with the TVQ or Gain Settings. Would that make a differnce?

My Question is if there are any possible upgrades that I could make without replacing the whole unit? Really looking for more powerful and useful fishfinding. Would adding a down vision unit like the CP100 make a huge difference?

Thanks so much for your input!
