Reviving an old thread, I have 0.02€ to drop here and probably a lot more in the chandlery
... My tacktick's bearing gave up, cups are stuck. The story costs me 2 trips to the mast, half day of fiddling and hopefully only a bearing to order. I am definitely not buying
an other tacktick even at half price
The ultrasonic calypso seems very interesting, no moving parts
, wireless and the pricing is also more realistic than the ~1000EUR pieces.
