I've been looking a GOOD bottom machine for 1500 or less.. the Si-Tex CVS-833C sounds pretty good 1kw output hi-def power mode etc.. Does anyone have one? What I'm looking for is good bottom definition. SI-TEX also offers a high performance thru hull transponder for this unit.... kind've pricey but I'm guessing that this is one of those "get what you pay for situations"
