I've been using a Fishing Buddy on my tube for about 4 years. It has worked great. The only problem I've had is it will double the actual depth it is reading. A few weeks ago in Tahoe the guide I took had a Bottom Line depth finder and he said that was usually due to bubbles on the "eye". It only happens rarely and is usually fixed instantly by turning the unit off and on. I've been using it in the ocean for over a year now with no problems. If you don't use the light the batteries last a long time.

The model I have was $180 when I bought it. When I bought it they had two models and mine was the more expensive one. I think it matches the middle-of-line model they have out right now.

I used it with the Fishin' Buddy Holster available at Cabela's (http://www.cabelas.com/texis/scripts/store/+/CatalogDisplay/displayPOD/CabFALL1998/CabFALL1998ACAm/IA533X). It worked okay but was kind of flimsy. I have since built a PVC holder for it that works much better. I now use the Holster as a cup holder.

I love the depth finder and would not like going out without it. Since I usually fish pretty shallow and for halibut it's not really a "fish finder" but more a "depth and structure finder". I also like instantly knowing what the water temperature is.
