Hello all!!! Ive got this friend who has takin me fishing on his boat for the last 5 years and refuse's to let me pay for gas or anything. Anyways he has this deterioration of the spine , so he just bought a top of the line Scotty downriggger to make things a bit easier on him. Problem is his fish finder sucks. 75% of the time it doesnt even work...it doesnt read bottom...In the 80's when i was rich and famous (now poor and infamous) i had a top of the line Lowrance fishfinder that did the same thing. Sup with that? Anyways...I want to buy this guy a fishfinder to show my gratitude...I dont want to spend more that $400 and would prefer to spend less. The key ingredients are
1. It works all the time
2.It has a depth alarm/warning
3. When it marks a fish it also has a number next to the fish that shows the depth
4. Its easy to use

Thats it. Dont need any other bells and whistles. Please help me out. Thanks in advance!!!!!!!!!!!
