I've had my Mega 360 for a couple of months now and am still in learning mode with it. I'm using it for Striper Trolling so it's not really a "normal" use case but I'm finding it very effective.
One question I have at this point is how to interpret distance from the Mega 360 pod to a specific object. I've attached an image I captured with a couple of schools of small Hybrid Stripers in the water column and have added an arrow to the area I want to focus on.
You can see from the image that I'm trolling at 2.8 MPH and over a 37' bottom. I realize that the arrow is pointing at shadows being cast by the fish in the water column at about 11:00 but, for this discussion, assume those shadows are actual fish returns.
My specific question is, for the objects at the arrow on the 75' range ring, are they actually 75' from the Mega 360 Pod or would I need to subtract out the 37' water column "ring" to determine their real distance so they would actually be 38' from the pod? In general, I would like to have a group discussion on interpreting object distance with the Mega 360. Would love input from the experts who have been using the Mega 360 for a while.
FYI, my Mega 360 is mounted on a rail about 3/4 of the way back on the helm side of my 21' pontoon. My Downriggers are mounted on the front corners of the boat and, if you zoom in on the image, you can see my 2 downrigger balls, the right planer board (with wake), and the Mercury outboard lower unit with cavitation trail from the prop. The right downrigger ball is just to the right of the bow of the boat icon, the left downrigger ball about 10' to the left of the bow of the boat icon, and the motor is just to the left of the stern of the boat icon.
It's amazing the detail of what you can pick up with the Mega 360!
