All in all it looks pretty close. Im gonna download the manual for it and compare to see what all the features are as far as setups. Im guessing there isnt an oversize battery that fits it. Is the rear screen removeable so you could trade it out for the larger batt pack? Dont really need a rear screen and 70 min wont cut it for the dives we do. Most are 90 to 180 min long w/ deco.Ive only had the gp go dead on 1 dive and that was pretty close to the end of the dive at about165 min or so. Thats using the wasabi extended batt pack. Like the wasabi batts alot better then the gp oem. Agree u really payin for a name but depending on the features u may also b payin fer better software also. Actually got a great deal on mine. Have a gp 3plus black. Got it bundled w a hispeed 64g card. 2 housings.6 back doors.remote.1 standard batt. 1 xtended batt. Usb cable. 4 sticky mounts.screws.ect. for 380 shipped around xmas. Was too good a deal to pass on. What software are you using?
