Garmin echo 151dv
 

I have a Garmin 151dv and I know it's not the greatest thing in the whole world butt what are some easy pointers to help make it easier to understand how to Mark fish or look for certain spots and get more fish on the ChumBucket also I need to get with some people that can show me some easy techniques on trolling for rockfish this season

I dont have one but if you search your unit on YouTube there may be some good videos on using the unit for you. Best wishes
