hey guys, finally get to use a sonar, borrowing a friends vex. are the buttons marked clearly on them to tun the gain, depth, and possible intereference? Ive never used a sonar before and wouldnt like to waste time on ice figuring it out, like help with the basics of operation. I know get the ducer at the bottom of the hole for optimum signal return already.
They are pretty simple to use and it shouldn’t take you long to learn how to use one. I would recommend watching a short instructional video and the link below should direct you to the page. After using one, it will be tough to go fishing without one! Good luck!
If it’s a Vex FL18 the IR buttont is the gain button pushed in up to 5X (keep pusing till no more IR), the dial with the 1X, 2X, 3X is used for depth, if you are fishing 5-20 FOW use the 1X setting, if you are fishing 20-40FOW use the 2X setting. Again, if it’s a 18 that you’ll be using the zoom feature is the middle dial which is best used on click to the right or turned to the zoom feature then you will be using the leftside of the Vex from the 0 to 6′ off the bottom.
Hope this helps
