Depth Finder Accuracy / Flashing

[tatoweb]

I also had the depth flashing problem and it was the lid of the canister falling apart. I tried multiple times and ways to close and secure it but nothing worked. My last resort to secure it was using duck tape. Then no more issues with depth readings.

So it looks like we will be taking delivery of a brand new R23 sooner than expected and I hadn't even thought about the type of transducer installed on the boat until this discussion. I've always had transom mounted transducers on our C-Dory and don't know a lot about In Hull transducers. Our new boat will have an Airmar P79 installed. I know this is a 600 watt traditional transducer, not CHIRP.

My question: For those of you who fish on their Tug, does the P79 provide adequate fish finding capabilities? If I wanted to change out the transducer, how difficult would that be? I've never owned a boat with the level of fit and finish that these boats have so I would be a bit reluctant to start changing things around. The CD was basically a blank canvas.

Thru hull transducers are better than surface mounted, but I have never had an issue identifying fish with mine. When they are there I see them. If they are biting is a different story.

When we took delivery of our 26 Cutwater we had the same problem. It worked good on delivery while running on the river. We then went for a cruise on the lake (Michigan) 2' waves and it started acting erratic. I found that some some of the propylene glycol had liked out. I lifted the transducer off, got some more fluid,toppped it off, worked great! Until the next choppy day on the lake. Two things were wrong 1) There wasn't an o-ring installed on the housing to seal the fluid from leaking out.2) There are two tabs on the lid that is attached to the transducer one was broken off. The broken tab is not that obvious unless you are looking for it. Being the boat was new I wasn't looking for it and assumed the missing o-ring was the culprit. When I installed it (push down and turn the lid to lock it) the lid seemed secure and locked. It would come loose again ,and with further inspection found a tab (small tab) was broke off. Richard from Ranger parts assisting me with retaining the new lid and no problems since.

So I finally got back down to the boat and checked things out again. It doesn’t appear to have leaked much out, but I definitely don’t have an o-ring either. It’s just the plastic transducer twist locked onto the plastic container, which appears glued to the hull... wonder if figuring out how to get an o-ring will help solve my problems.

It will fix the problem. When mine was missing the o-ring it didn't leak until I went out in a chop and then it would leak and start malfunctioning. Did you check the tabs also? Call Richard at Ranger he will set you up with the right o-ring.

Have had the same problem on our 2016 30CB gets pretty aggravating and then where it's located is a bear to get to it. Need some sort of hatch for us bigger guys with big arms and sausage fingers. Last time we went out flashed 22'6 most of the trip.Decided to reboot then showed absolutely nothing. First timer on tugnuts. So much great info. Wifes been complaining about shower pulsing and the aft wash does same thing. Great info on theses technical discussions. Thank you for all the great info.
