Hey guys,
New to the forum so apologies if this isn't the right place to ask this. I'm having an odd issue with Mega Side and Down imaging. It works great up to about 30 ft deep where it will turn dark and basically unreadable. If I flip it over to the 455khz setting it will show normally again. Correct me if I'm wrong but I thought Mega was good to about 75ft deep and with an SI range of about 120ft on each side. I was not able to grab any screen shots but I will post them later if needed.
Thanks!
