Maretron TFT-5H Ultrasonic Tank Sensor SAE Focus Tube

If your tank has an SAE fitting and the boat is either a planing powerboat or a sailboat that is likely to pitch and roll more than 6 degrees, you should install this hull focus tube. The tube will enable accurate readings to be made for pitch/roll angles up to 15 degrees. This tube can be cut to length to match the tank depth.

For use with the TLM100 and TLM150 tank sensors.
