It's just a plastic ground sleeve.

Basic device but sufficient for my use in coastal. Used with probe glued to the hull without problems, drawback retraction wheel with incomplete blade. Fragility of the latter magnets degraded by corrosion.

The log is a proven, reliable and inexpensive product, which fulfills all conditions of sailing.

Question about delivery contents

Flag of English Dear Sirs, I'd like to ask, what is in the delivery package of NASA Target 2 LOG? The 2nd picture shows the sensor, the cable, the display, but the item description has no information about the contents. I have another question too: the paddlewheel speedsensor and the thrue_hull_fittings are knock-down? The picture shows an assembled part, and I don't know what kind of it is in effect. Sincerelly yours Zsolt

Hi Judith, Thank you for your answer about the package. I'd like to ask, as I've done in the original question: are the paddlewheel speedsensor and the thrue_hull_fittings knock-down? Last, not least, how long the connection cable included to the LOG2? Thank you Have a good day! Zsolt

Hi Zsolt, yes the transducer and the through-hull fitting are separately. The connection cable of the transducer is 7 meter long, in case it´s to short you can easily extend it by using the 7 meter extension cable (Art.: 93590).
