bottom loss

Hi guys.

i have a bit of a dilemna. with my new sounder/transducer coombo i seem to be loosing bottom when fihsing in depth above 30m at anything above 4-5 knots.

i have a hds live 12, with the 3 in 1 transducer on a carribean reef runner. i have tried playing around with angles of the transducer and ping, scroll speeds etc, but nothing seems to make a diff.

strange thing is that when in about 20m or below seems to read well at up to 18knots.

almost seems liek not enough power?

any suggestions? most of the fishing im gogin to be doing will be in 30m and deepr, so trying to scout new ground will become very frustrating at 4 knots.

chgeers!

 Most of these 3 in 1 type transducers are only 100w.. Rated to about 50m in down scan mode.. A bit more if used in traditional mode but they are rated for fresh water.. From memory the reef runner is a bastard to get transom mount units to work, and not enough area in bilge behind the fuel tank to mount a in Hull unit

 I had the same problem on my Reefy as well. I have stick the total scan in reverse to the bottom of the hull and is working well. Now I can also get sidescan as well without the motor being in the way. I ran the cord into the drain hole as well so you hardly know its there

I am North of the River if you want to have a look

thanks mate. i have heard a couple of people talk about reversing the unit. something to do with where the crystals are. how did you fix it to the bottom?

any chance you could post a pic? i am also north of the river, so may take you up on that offer once this weather clears. much appreciated.

thanks heaps for the input!
