Hi All, Today we made a trip to a small pond to test the two sonar transmitter units i recived from David Bartsch. We found a ice hole and made one 58 paces from that one. Set up the two units just by lowering the hydrophones and transmitters a foot or two in the ice water, the ice was a foot thick. The hydrophones pick up super sound. The voice transmitting worked well but next test i;m going to mount the underwater parts to a poll so i can point the units at each other for better pickup and transmit. I'm happy, thanks David. Dave-thats $200 plus the four amp kits-$45 ($245 per unit).. I think the next test this week will prove more than 200 feet from one ice hole to another. I have been working on my sub at a shop where its warm,, working on the last window #12. The minkota motor thruster swivel thru hulls- cost $100 a set if anyone wants a set. Leslie Katschor |
