timmy180883 Posted December 15, 2014 Share Posted December 15, 2014 Hi raiders, I just installed a Garmin echo map 70vd with down VU, I used it for the first time today and it worked well, it is a lot better then my old lowrance unit and was good value for money, but water splashes up when going over 10mph, when I go max speed for my quintrex which is 30mph the water streams over a 1.5m high, I tried lowering it and raising it as far as The screws let me when I installed it but same issue, did I install it too low or high ? I have have attached some pics, I would appreciate your feedback thanks Link to comment Share on other sites More sharing options...
NaClH2OK9 Posted December 15, 2014 Share Posted December 15, 2014 I'm no expert but would have thought you would have white water noise and needed to drop it a bit. If all else fails get a deflector. Link to comment Share on other sites More sharing options...
Geoff Posted December 15, 2014 Share Posted December 15, 2014 I may be way off course here but I think the actual size , in particular the length , which you cannot do anything about , is the problem & when on the plane the trailing edge "digs" in causing the spray to occure. At presant you have the transducer leval with the bottom of the boat which is the normal position. Perhaps try to raise the trailing edge slightly so it's leval with the water when on the plane rather than the bottom of the boat. With this change it will not be digging in so much.

a boat Posted December 15, 2014 Share Posted December 15, 2014 Fit a spray deflector and you would of thought the place you purchased it from would of mentioned that. Link to comment Share on other sites More sharing options...
locodave Posted December 16, 2014 Share Posted December 16, 2014 Hi mate, I have the same transducer. I will send you pics of mine if you want. I don't get a rooster tail like you. From what I see, it looks to far down. Mine is a lot higher, so that round curve on the transducer sits level with the boat. Also, unless it is the angle, the transducer doesn't look straight. Another point, I personally would of moved the transducer to the right as the bottom of the boat seems a little flatter there and you won't get much turbulance.

a boat Posted December 16, 2014 Share Posted December 16, 2014 A glass boat like yours Dave will allow the transducer to mount higher, if the OP raises the transducer to be equal with the bottom of the boat it will lose reading due to the fact that alloy boats are not very "clean" thru the water. If he is getting good readings up on the plane then I would fit the spray deflector and it will stop the rooster tail. Link to comment Share on other sites More sharing options...
locodave Posted December 16, 2014 Share Posted December 16, 2014 Good point What about moving it to the right a bit more? Link to comment Share on other sites More sharing options...
a boat Posted December 16, 2014 Share Posted December 16, 2014 It will be all trail and error-there is no way of knowing what it would achieve without trying it-could make it better could make it worse. Link to comment Share on other sites More sharing options...
timmy180883 Posted December 27, 2014 Author Share Posted December 27, 2014 Hi guys, sorry for late reply, thanks for all your input I think I will put a deflector on as I am getting good readings, thanks for all your help tim Link to comment Share on other sites More sharing options...
martoiscool Posted January 29, 2015 Share Posted January 29, 2015 Hey Timmy, How did u go with the spray deflector? I just fitted a new transducer and I'm having the same problem. Curious as to if it interferes with the transducers signal Link to comment Share on other sites More sharing options...
