I had a Bottom Line tournament 3310
with the first Sidefinder technology, and liked it a lot. I busted the transducer and had to wait nearly 6 months to get another and I paid $10 more than I did for the whole outfit. Bottom line was bought by Johnson Outdoors but never produced again, however you can order some parts. While in for service the transducer was busted again. I was telling my brother about it and he said, "I think those transducers for the Tournament series are all the same. I have one of those. ****, I'll send you the whole thing." He sent me this, a Bottom Line Tournament HR
A big step up from my 3310. Has anyone ever used (or using) one of these? It also has a flasher, but I'm not really sure what a flasher is supposed to do or what it's advantages/disadvantages are..
