BiorowYes (and rent)Wireless Swivel (Gate) measures the strain of the sleeve against the back of the gate and the position/angle of the gate reletive to the boatAbout £5500 for a single, check price listXXXXXXXX (optional wireless force measurement for an extra £250 per blade)XX (£400 extra)XXProbably the most complete solution, possible to get sesnors to measure all parts of the strokeComlicated set up, some documents suggest it can take an hour to set up, so not a "attach and leave" solutionhttp://www.biorow.com/PS_tel_files/BioRowTel%20Quote.pdf

Cox/Coxless device inside the boat receives the data from the swivel and can display it real-time and record for later reviewLightweight and simple for the rower to useQuestion regaridng the reliabilty of the wireless connection/dropped connections?
10
Optional extra wiring for speakers/coach radioModular wireless system - So easy to buy what you can afford now and then add more at a later date
11
Speed measured using an impellerCan use different blades as you wish, not fixed to one set
12
PC Software for post outing analysisOarlocks have a wearplate which is replacable so no need to replace oarlock as often

Powerline Rowing InstrumentsYesWired Swivel (Gate) measures the strain of the sleeve against the back of the gate and the position/angle of the gate reletive to the boat£2595 plus VATX(X) (£900)XXXXXXCan use different blades as you wish, not fixed to one setRower is fixed with using one set of gates, cannot use manufacturer specific gates/Magik Gateshttp://www.peachinnovations.com/tourintro.htm
14
Speed measured using an impelllerWell established in the UK, used by many including GB and AUSOarlock will be worn during use, therefore at some point will need a costly replacement
15
Strethcer force measurement optional extraModular system - Buy what you can afford now and add more sensors laterComplicated to install due to wires, difficult to move between boats

Weba Power MeterYes (updated model in 2017)Essentially an updated wireless version of the Blade sensor model, but using an Android app as controlling device£400 + VAT + Postage from EUXX (Android app + phone accelerometer)X (Phone GPS)X (but overall arc angle only, no measuremnts relative to the pin like catch or finish angles)XX (through Android app + Bluetooth)only if the coach has the android phone/app, then the rower has no access to the dataXX (user hangs known weight on blade to calibrate)Needs two people to set up/calibrateBluetooth smart connection means 1:1 connection to a single smartphone, cant connect and compare multiple graphs livehttp://www.weba-sport.com/en/products/oar-power-meter-en
32
Sensors attached to the blade shaft close to the sleeve and measures strain through the blade Simple setup, just attach to blade, calibrate and fire up the android app - Can even pass blade around within a crew without needing recalibrationReview function post outing on app is limited, need to install and run PC softarwre
33
Data displayed live on android appNo direct wear on equipment in useLarge device that attaches to a single blade, not ideal in sculling
34
Calibrated by handing known weights from the blade after fittingRelatively inexpensive, particuarly if you already have an android phone
35
SmartOarYesSensors permanently attached to the blade shaft (either provide own blades or order and have blades posted to them for fitting). Sensor is attached close to the sleeve and measures strain through the blade £723 + VAT + Postage from USA (inclues price for shipping blades of choice)XXXX(X) (£4000)XXEasy to switch between boats (no wired attachments to boats), no de-rigging required or re-calibration. Rower is fixed to one set of blades, cannot switch to a different set without removing the SmartOar and sending it back to the manufacturers to re-attach/reclaibrate http://www.smartoar.com/
36
Optional extra coaches tablet for real time analysisIn crew boats, one pair of blades could be bought and quickly and easily switched between positions in a boat (i.e. from stroke to 2)When ordering blades must be bought/provided for initial installation, high costs for shipping outside the USA
37
PC Software for post outing analysisOther fittings are not affected (so you can use Magik gates/biorig shoes etc)To measure boat speed/rate rower will need to have their own solution (i.e. NK Speedcoach)
38
Device is not in contact/wears dring use, only the sleeve which is a nominal cost to replaceNo instant feedback screen for the rower unless you buy the expensive coaches tablet
39
No distractions for crew during outing

Nielsen Kellerman Wireless GateYesWireles gate for sweep/scull£599XX (From GPS2)X (from GPS2)XXX (from GPS2)(X) (unclear but looks to be planned with additional adapter)XNK have good history in rowing so expect good qualtiy equipmentBluetooth suggests only a 1:1 connection i.e. a gate could only talk to one GPS2 at a time so the whole crew woudlnt be able to see everyones curves simulatneously https://wordpress.com/read/post/feed/9207568/841075086
41
Connects to NK GPS2Working with BioRow so hopefully high quality data and analysisGate parts do not look replacable so issue of wear
42
Will display power, arc, curve etcWireless so easy set up on boat, and move between boats if requiredQuestion regaridng the reliabilty of the wireless connection/dropped connections?
43
Lightweight and simple for the rower to use
44
Can use different blades as you wish, not fixed to one set
