I have the elite 5 dsi gold model which maxs out with depth about 300 ft or so. I didn't realize that when I bought it. Other than that it's a great unit. GPS is good on it too. I did have it marking my dr balls, but I must've adjusted something too much. Will try tipping the ducer back some. If I could do it over again I would've gotten the HDS 5 or 7.
