I've been using Hydrowave for 2 years now..
The thing flat out works..I feel it puts the fish in a better mood..Yesterday it was on crayfish on gravel all day..I vary the delay & sound depending on wind..My livewell was full of crayfish at end of the day..I've used it on power pattern with great success during a recent night tx & we caught em good..In the winter I like deep bait sound when I'm fishing 40ft & the bait is balled up..
It's not gonna create miracles over night,but I feel it's been another great tool that I am really starting to figure out..
For the guys who been thinking about it,& have any questions about it,feel free to ask..I'm by no means a product pusher & would never promote something if I feel I haven't given it 100% trial first..its no gimmic.I promise you..
