I have read where alot of people use a slow sweep speed with the MXT. Are we talking slow like using an explorer? Will the slow sweep speed have an effect on the depth vs a faster speed? I mostly use the Fisher F70 and you need to have a good sweep speed or you will lose depth. I would like to work some areas using a very slow speed because of the trash contents, would the MXT help me there as far as picking up targets are reasonable depths? Thanks for any info. HH John
