[gmc60]

Anyone know what wedge to use 2deg,4deg,6deg, on top of the arch for 10mph EST speed in fog?
I have 2- 454 and bravo 3 std boat (gen also) but i only see good targets at 2-5 mph its a Simrad 3g, changed it from a Raymarine .
And i new tower 8in high whats the dif if it leans forward or Backward ?
Thanks

Radar is line of sight, if the antenna front is tilted up when runn8ng the main bean will shot over targets. The farther from the target the higher the overshoot. Opposite if tilted down.

Radar should sit flat. What is the angle at 10kts?

10kts will more than likely have you bow high. What is the angle now?

It is flat OEM with 5 in tower i did not know if it already has a tilt or if anyone had tried a wedge already.

Also maybe i need a 8 inch tower too so it can see over canvas poles ? Its 5 inches now
