sweet little unit The 688 DI is a great little unit. I have a 900 series at the console of my boat and I wanted another down imaging unit at my trolling motor. You cant beat this fishfinder for the money. It does everything I hoped it would and more. Once I find a spot I want to fish with my other unit I hop to the bow and start using my trolling motor. I love not having to run back to my console to mark waypoints anymore. DI is very good on this unit as is the gps. If you want a great fishfinder without breaking the bank this is what you need. If you want side imaging you can get that for just 200 more dollars. I really like the price points of the 2014 humminbirds too. March 1, 2014
DO NOT BUY! Keep Looking! Nothing but issues, frustration, and hassles! GPS WON'T stay locked on. Called Humminbird numerous times and finally told to return head unit for replacement to BPS. Still will not stay locked on. Past the 60 day Bass Pro refund even though we just received the new head unit. Should have returned it, got a refund, and been done instead. Now, Humminbird wants pics of the unit to help determine the cause. Humminbird needs to find a solution NOW or gives us a refund. DO NOT BUY. DO NOT BUY. DO NOT BUY. DO NOT BUY. DO NOT BUY. Keep looking to save yourself all the issues, frustration, and hassles. July 23, 2014
Excellent MidLevel Sonar/GPs I've had no issues with this unit and very satisfied with the performance. This unit can be customized to suite each user preferences. The GPS gains lock in the same amount of time as my handheld and vehicle Garmin units when powering up "cold". The number of screen display choices and color is very good. The detail of structure is excellent in all modes. When purchasing a Navionics map card be sure to check compatibility of the different map packs available. The unit is voltage sensitive, will shutdown when voltage is low. I had this happen a few times with incandescent type anchor, bow nav & gauge lights were turned on, the system voltage would drop. I switched my bow nav & anchor lights to LED to reduce current draw and haven't had any issues since the change. October 18, 2014
Good product for the price. I bought this to replace the cheap fish finder that came on my new boat. This is the first Humminbird that I have owned and now I will never go back to the other brand. The other reviews talk about the cold start, this is no different than a hand held gps. I turn mine on as I am preparing to launch and by the time I get to the water it is working fine. The images are great, it shows the bottom detail very well and there are so many screen choices that I can use the one that works best for the lake that I am on. I did not know about the different software that is availible until after I purchased the unit. The software will be an extra bonus for me in the future. The charting and down imaging work better than I had expected. Between all the different frequencies I can get all the detail I need to find fish and structure. I am very glad I bought this.

Details: 
Everything that I read about the Humminbird 688ci HD DI Combo is great, and I understand that it has the capablity of being used while ice fishing, but what additional accessories are needed to take it on the ice and ready to use? I'm getting geared up for a December ice fishing trip and I need the right equipment. This Humminbird 688 unit sounds like it will handle both ice and open water, which is what I am after.

Yes you can. I use navionics premium with mine. The 600 series is not compatible with the platinum cards from navionics though. Hot maps is another option for you with the 600 series from HB.

Yes. The standard transducer can be adapted to the trolling motor with the AD XTM 9 or your new unused transducer can be sent in for exchange to the Trolling Motor Transducer.

The Side Imaging and Down Imaging transducers can be adapted to the foot of the Trolling Motor. At this time, there are no plans to incorporate that type of sonar into the Trolling Motors.
