I do deep saltwater stuff up to around 1000ft, bought the 998 humminbird thinking it would work in deep water, the specs state itll work with the stock transducer up 1500', could never get it to read in over 300' of water, so I figured Id buy the 1kw ducer from Airmar, the transom mount TM260 thinking I would get readings of up to 3000' like the specs stated. Went out in 750' of water and would barely get a bottom reading and it would lose bottom more than it would track it, I messed with every setting and nothing seemed to help. I dont know if humminbird is just full of crap with the specs or if there is something wrong with my unit, has anyone else had any deepwater experience with there unit, I spent a fortune on this setup thinking it would at least perform near the specs but its no where close. Very dissapointed!!!

I think these sonars are for more shallow depths. Without a homemade towfish it is hard to get anything useable below 100 feet. In fact for our use we stop HB at 60 feet and go to another brand. We do have a towfish with 60 feet of cable and that will help the 100 feet at times..although that is a lot of towfish to control..
Some of the guys here have made great fish and gets some better results. maybe they can add to this.
Also search this forum for towfish and look at what guys have posted..
