So I just hooked up my Striker 4 today and took it out for a spin. Love the details and features but a couple things don't make sense.
1. I know the depth of the pond I'm scanning and at no point did it ever come close to reading that depth. From looking down and comparing with the graph, it thinks the tops of the hydrilla that covers the entire pond is the bottom and even shows red as a strong return. Why would vegetation be strong return and why can't it see the actual bottom. Changing the depth range doesn't show any obvious difference between the returns of the hydrilla and the returns of the bottom so I can't even tell where the bottom is on the screen and use the depth scale to measure it manually. What's the deal?
2. I noticed something new on this units graph that my previous Piranha Max 4 didn't have. From the depth of 0 to a varying depth of around 1-2ft all around the pond, there is red as if there is something there floating at the top of the water but I can see there is not. What is it picking up??
Update: I've fixed #2, found a setting I didn't see before to show/hide surface noise
