If your budget better fits the Hook2 series, it is a good unit and very nice for the money.
NOTE: Lowrance makes the HOOK2 7-Inch unit in a 7xTS model and a 7TS model. The 'X' indicates no lake mapping. You will have a blank screen to provide you GPS trails and Weigh-Points, but no mapping of the lake. If you don't need lake mapping the 7xTS is an awesome unit. For more info than you may want, the Hook TS models provide Downscan, Sidescan & Sonar. The Hook HDI models provide downscan & sonar (no side scan). Hope this helps.
Go for it, great units!
