Well I'll comment since I own one.
I have the 5000 model I believe. No bells and whistles just GPH and total gallons burned.
Bought in 1996.
Used on two different motors.
Very durable and scary accurate.
Will never own a boat without one that I use in any body of water other than my bathtub.
Sorry but I'm not familiar with all the new stuff they do but you really can't go wrong.
Good luck
